Title: A potential fix for speedo cable oil leak! Post by Ben on 05/13/12 at 17:33:14 Ok so here goes... Last year I had my '87 Savage get a new gasket set and piston rings. However, even after allowing time for break in and re-torquing engine bolts periodically, I noticed an oil leak. Wouldn't you know it. The speedometer cable was the culprit. So after a quick look on this wonderful resource known as suzukisavage.com, I promptly put on an o-ring of adequate size and composition as described by so many others here. This seemed to fix the problem, at least temporarily. I ride about 120 miles a day, round trip to work and back home. Eventually the dang o-rings gave out. So i replaced them. One and then another and another. The whole time I have been on a mission to find the OEM seal. This is not possible, it seems, without ordering a whole new speedometer cable. Well, I decided, if that was the case, that I would order one of the RYCA speedo cables and setup a mini speedo. After some correspondence with RYCA, however, I was told that there speedo cable does not include a seal. Puzzling, I thought. Not one to be easily put off track, I decided to give my local hardware stores a try. After some quick searches here, I located an image of the OEM seal. http://img338.imageshack.us/img338/317/oemspeedoseal.th.jpg (http://imageshack.us/photo/my-images/338/oemspeedoseal.jpg/) Armed with this image and a plastic spacer (that I had modified to be the size that was required), I headed off to hunt. After a long day of browsing I came home with quite a few hopefuls. http://img27.imageshack.us/img27/6308/everythingicouldfind.jpg (http://imageshack.us/photo/my-images/27/everythingicouldfind.jpg/) Total cost for everything was less that $5. One item in particular stood out from the rest. A Bonded Sealing Washer 1/4" radius. http://img685.imageshack.us/img685/5484/bondedsealingwasherpack.jpg (http://imageshack.us/photo/my-images/685/bondedsealingwasherpack.jpg/) This little guy has a conical galvanized metal washer that is bonded to and NEOPRENE seal. The seal's inner diameter is just slightly less than the metal washer's. http://img690.imageshack.us/img690/8826/bondedsealingwasher.jpg (http://imageshack.us/photo/my-images/690/bondedsealingwasher.jpg/) I unscrewed the speedo cable. Then removed inner cabling and slid the washer down the whole thing metal side down. This allowed the metal to go around the larger diamter of the part that inserts into the transmission. and also allowed the neoprene seal to snug against the inner speedo cabling. It fits perfectly (pics to come in the next few days. So now I am running it this way. After a few days I will inspect the seal to check for wear and tear. BTW for anyone who wants to try this. You can pick up the same one I have at Home Depot. Check the pic for the part number, but its in the hardware aisle. |

Title: Re: Permanent fix for speedo cable oil leak! Post by Sarge on 05/14/12 at 09:03:17 :)Someone else on this forum suggested using some yellow teflon tape (oil resistant) on the threads in addition to the o ring seal. I tried it 3 years ago and no leaks since. |

Title: Re: Permanent fix for speedo cable oil leak! Post by WD on 05/14/12 at 18:19:17 I just deleted the cable. End of leak. As in, not a drop out that hole without a cable in it. Cable acts as a wick. Haven't run a speedometer on the bike for about 6 years. No tickets, speeding or equipment violation. |

Title: Re: Permanent fix for speedo cable oil leak! Post by Ben aka ubergeek on 05/19/12 at 21:08:27 Update: I've ridden about 600 miles since I put the bonded washer on. No leaks at all. I will be posting a few more pictures soon (hopefully). As soon as I get the time. I also just finished my dyna muffler change. OMG. I cannot believe how much of a difference it makes. |

I have heard the same and have tried those as well. But it is not a permanent fix. I was going through o-rings about once a month. I have access to a wide variety of o-rings of different composition. None of them lasted very long. What I am trying to accomplish is a replacement for the oem oil seal. I have actually located the exact seal. However I would have to order $150 worth of seals in order to acquire one. This bonded washer is working so good though. After a few more weeks of running and some examination under magnification, I am just about ready to rewrite this topic and request it be made a sticky in the technical section. I am surprised every time I get off the bike and there is not oil leaking down my engine. I really think that this may be a better solution than the o-rings. And with this items availability, anyone who has an LS650 should be able to pick one up. |

Title: Re: Permanent fix for speedo cable oil leak! Post by Savage_Rob on 05/24/12 at 07:56:07 I like the idea of the bonded washer, as long as the rubber is something like nitrile, which is petroleum resistant. A lot of other types will break down too quickly. I'm interested to see how well it works for you. |

Title: Re: Permanent fix for speedo cable oil leak! Post by Savage_Rob on 05/24/12 at 14:53:53 I'm pretty sure WD doesn't use the stock tank. |

Title: Re: Permanent fix for speedo cable oil leak! Post by Ben aka ubergeek on 05/25/12 at 09:16:28 Not sure about wd or tank? Maybe posted in wrong thread. However I made a tiny discovery today. The seal is neoprene, not epdm like I had thought. I was trying to find a replacement for the epdm and low and behold google search hit on a neoprene bonded sealing washer. It was the exact part # that I had grabbed. I'm not sure how oil resistant neoprene is, but I think it might explain why there had been no breakdown of the seal so far. I plan on taking the pictures this weekend. I have Monday off so I should be able to get them done. I wonder how many people have had this oil leak problem... |

Nope. Jay313 asked what WD did with the hole created by removing the speedo. I responded that I thought WD did not use the stock fuel tank (in which the speedo is mounted), hence no gaping hole to consider. |

Title: Re: Permanent fix for speedo cable oil leak! Post by WD on 05/25/12 at 15:30:33 Correct, I run a dirt track race tank of unknown date/manufacture. Nowhere to run a speedometer so need need for a cable. I deleted the cable long before I swapped tanks, got sick of the gunk. Savages are a knock-off of an old British single (part Matchless, part AJS, part BSA) so oil leaks are expected. But NOT soaking into a water buffalo hide solo seat. Boofer... I run a glasspack, 15" apes, no turn signals, FLH rear fender and low beam only 7" headlight. I get pulled over out of curiosity. And the bike regularly saw 100+ mph on the coast and around Millington NAS... |

Title: Re: Permanent fix for speedo cable oil leak! Post by Ben aka ubergeek on 05/28/12 at 10:03:00 Here's the pics and some updates. I've been sick since I put this to test. So I only rode about 1000 miles. But as you can see, no leaks. http://img401.imageshack.us/img401/1042/imag0083rs.jpg (http://imageshack.us/photo/my-images/401/imag0083rs.jpg/) http://img823.imageshack.us/img823/6190/imag0085ri.jpg (http://imageshack.us/photo/my-images/823/imag0085ri.jpg/) http://img607.imageshack.us/img607/6775/imag0086r.jpg (http://imageshack.us/photo/my-images/607/imag0086r.jpg/) http://img41.imageshack.us/img41/4315/imag0087ld.jpg (http://imageshack.us/photo/my-images/41/imag0087ld.jpg/) This didn't look good at first but upon closer examination I realized that the problem was that my 25 year old speedo cable was not smooth. More pitted and corroded. This caused it to tear the neoprene seal as it spins. http://img13.imageshack.us/img13/661/imag0088ri.jpg (http://imageshack.us/photo/my-images/13/imag0088ri.jpg/) http://img137.imageshack.us/img137/3520/imag0089r.jpg (http://imageshack.us/photo/my-images/137/imag0089r.jpg/) http://img515.imageshack.us/img515/9836/imag0090r.jpg (http://imageshack.us/photo/my-images/515/imag0090r.jpg/) http://img37.imageshack.us/img37/7527/imag0091rd.jpg (http://imageshack.us/photo/my-images/37/imag0091rd.jpg/) I put the whole thing in a drill and used some sandpaper and steel wool to smooth it out. Nice and clean. Let's try this again. I also put some lithium grease on it where the seal sets. http://img96.imageshack.us/img96/2782/imag0092lb.jpg (http://imageshack.us/photo/my-images/96/imag0092lb.jpg/) http://img818.imageshack.us/img818/4963/imag0093l.jpg (http://imageshack.us/photo/my-images/818/imag0093l.jpg/) http://img685.imageshack.us/img685/338/imag0094vo.jpg (http://imageshack.us/photo/my-images/685/imag0094vo.jpg/) I cleaned this part as well. http://img845.imageshack.us/img845/8554/imag0096sw.jpg (http://imageshack.us/photo/my-images/845/imag0096sw.jpg/) See how nice it fits. Almost like it was meant to be there. http://img707.imageshack.us/img707/2689/imag0097z.jpg (http://imageshack.us/photo/my-images/707/imag0097z.jpg/) All back together. I'll give it another 1000 miles before I check it again. http://img99.imageshack.us/img99/2117/imag0100v.jpg (http://imageshack.us/photo/my-images/99/imag0100v.jpg/) If anyone else has tried this. Let me know. My bike is an 87 so my speedo was really rough on the seal. I'd be interested to know how it fares on a newer bike. |

Title: Re: A potential fix for speedo cable oil leak! Post by HondaLavis on 08/17/12 at 00:59:15 After removing my tank and disconnecting my speedo, my seal went awol ::) so I'm trying this method. However, I installed with the metallic side on top, bonded neoprene on the bottom. I'll update in a month or so after I've got 1,000 miles on it. |

Title: Re: A potential fix for speedo cable oil leak! Post by lacon on 08/22/12 at 07:16:58 I tried an O-ring (freebie) & it did not last long. It was 1/2" O.D. x 3/8" I.D. which made it only 1/16" dia. thick. I believe a 1/2" x 1/4" might well work, but did not have one to try. I just put in a 1/2" x 1/4" x 1/16" thick neoprene flat washer. (At Home Depot in the same drawer with the bonded washers) If this goes, my next trys will be to double the flat washers to get 1/8" thickness, or the bonded washer with a flat neoprene washer on the metal side (sandwich the metal washer), or look for a 1/2" x 1/4" O-ring. I guess I'm a little leary of just the bonded washer because one side is still a metal to metal seat - (although that seat is concentrated to a knife edged ring because of the cone shape). |

Title: Re: A potential fix for speedo cable oil leak! Post by LouSiana on 08/22/12 at 08:57:49 You might try this OEM number from Suzuki: 34943-11030 This ist the perfect sealing ring which is used on other speedo cables and tachs by Suzuki. :o)) btw: if this seling gets lost, it sometimes hides under the starter motor if you don't find it on the road or garage floor. A quick take out of the starter may save lots of time. |

Title: Re: A potential fix for speedo cable oil leak! Post by Oldfeller on 08/22/12 at 17:59:16 Part number is good, someone needs to order one and verify it works. http://www.bikebandit.com/search?q=34943-11030 |

Title: Re: A potential fix for speedo cable oil leak! Post by Oldfeller on 08/22/12 at 18:16:51 LouSiana searched through lots of other 'zuki cable sets and discovered the correct stock OEM Suzuki seal running under part number 34943-11030 for $2.74 plus shipping. This ring lip seal has eluded us for years but it is now found and identified. http://img338.imageshack.us/img338/317/oemspeedoseal.th.jpg Part number 34943-11030 ring lip seal for $2.74 http://www.bikebandit.com/search?q=34943-11030 |

Title: Re: A potential fix for speedo cable oil leak! Post by Digger on 08/22/12 at 19:42:17 It will be interesting to see what luck people have with the OEM seal. Mine started leaking not long after I got the bike (I bought it used with 70 miles on it back in 2001 - see signature block for specifics on the bike). I replaced the OEM seal with an o-ring when the bike had about 600 miles on it. A few years back, that o-ring started to leak, so I swapped out the old o-ring for a new one. The bike now has 12,500 miles on it....and the second o-ring is still hanging in there. I'm guessing that a well-chosen o-ring will last longer than that OEM seal will. Like I say, I'm lookin' forward to hearing about folks' real world experiences..... |

Title: Re: A potential fix for speedo cable oil leak! Post by Cavi Mike on 08/22/12 at 20:10:58 "TACH CABLE OIL" Is that the right part? I don't see an image. |

Title: Re: A potential fix for speedo cable oil leak! Post by Oldfeller on 08/23/12 at 06:41:16 Digger, Just playing the numbers game, over the years there have been 10,000's of speedo cables using that sort of seal on our model alone -- and lots of other models that use the same sort of cable set up off the transmission -- that don't leak for their owners. Just playing the numbers "as seen" if you have a smooth surface on your inner cable it should work well for you for a lot of miles. When these seals do leak, generally there is a reason behind it. Wear is the simplest, and a little bit of roughness on the inner cable shaft can certainly make that happen. So can a badly formed cable square end, which would make for an oscillation in the seal shank as the thing spins. ========================= Cavi, Both Ron Eyers and Bike Bandit are saying "TACH CABLE OIL" as the description of that part number. My goodness, I have searched for this seal before and saw this "oil" being offered up many times, and I ignored it because I wanted the seal that Suzuki wouldn't sell us not some stupid heavy gear oil that I had by the quart already. So, egg on my face too -- right along with all of the rest of us who have been seal searching before. This "TACH CABLE OIL" is apparently some sort of Nipponese/Engrish shorthand for "Tachometer Cable Oil Seal" as the part looks like this: |

Title: Re: A potential fix for speedo cable oil leak! Post by LouSiana on 08/23/12 at 08:53:03 Hiho and thanks for your replies! I don't think it's a matter of luck getting rid of oil marks that way. All the proposals may work as well (O-Ring, rubber coated washer), but if the original seal doesn't work what it is for, you should not blame that ring seal. As Oldfeller pointed out, the reason of leaking and destroying the lip of the seal may be roughness, corrosion or radial play, he called it oscillation. Which might be as well as de-centered action, maybe from unexact make. There are many S40 or Savage's that do not leak, even if there's nothing like an O-Ring or the "Simmerring" as it is called here in Germany. My Engine in the sidecar-Savage does not and my "Solo" doesn't, too. Just like others I know of and also know, they have no seal mounted. Others wonder and complain about remarkable amounts of oil leaking down from the cylinder head cover. Panic!! Mostly then the oil crawled up in the speedo cable and does not know where to go then with reason. If the speedo is oil stained from the underside and one remarks oil reflow flom the speedo cable it's easy to explain. This little a**hole :O)) goes away and often got lost every second attempt to take off the fuel tank. Maybe it's a difference in the clearing of the speedo-shaft in the engine case if it will leak or not without sealing and maybe there are differences how the oil gets out of the gear shaft bearings. The lubrication of the speedo drive shaft is more random from oil drops flying around in the case and not fed from the oil gallery. Hope you get me right, I'm not a native speaker of the english language. So I beg your pardon! Regards, Lou |

Title: Re: A potential fix for speedo cable oil leak! Post by Oldfeller on 08/23/12 at 09:46:05 Hey, you can struggle with our awkward language all you want, any time you want -- we are so durn good at at our English language we never even LOOKED at the picture for the "TACH CABLE OIL" that was sitting in front of us for all these years. It took a German who didn't trust his English to find what the Japanese translators had hidden in plain sight for all those years .... Lou, what does the part number 34943-11030 part description say in your German parts lists ???? Ours says it is "oil for the tach cable" which is a very poor job translating "oil seal" from Japanese into English. Did they do any better translating it to German? In any case, you have our thanks for finding our mysterious lost seal. |

Title: Re: A potential fix for speedo cable oil leak! Post by LouSiana on 08/23/12 at 11:12:27 Hihi thanks in advance! ;) Most of the parts I need I get from Netherlands, CMSL or another fellow friend, who made up one of our german Savage-forum. There, I must confess, I got that hint to this item. (As we say here, it's not grown on my own dung heap...) This sealing ring is used in many other bikes, that way the number seems odd compared to the "24B0xxx" numbers for the S40 or Savage. Anyway, if it does what it is made for, I don't complain! By CMSL it is called "Oil seal" (they have their shop in english, too) but usually it is called "Simmering" here (that's Jargon, the right description would be "Shaft Sealing" = Wellendichtring). You even may get such sealings here in some shops dealing with ball bearings and other machine parts like hydraulic assemblies and so on. It's easier here because we have all that stuff in metric measures (and don't we both may get crazy if we ecounter things in the respectively "wrong" measure? Inch based tools and bolts and so on are here something like a challenge, maybe metric stuff is the same at your site. Sure you got the Idea!) and those things have their defined and standardized measure. Inner diameter, outer diameter, thickness. There may be other outer diameter measures for 7mm shafts for example, but they often compare with measures from ball bearings, saving machining time. I believe, that won't be new to you, hm? ;o)) Anyway: If Suzuki refuses that sealing in their part listings for the S40 and Savage, you know to beat them now! |

Title: Re: A potential fix for speedo cable oil leak! Post by Oldfeller on 08/23/12 at 11:25:14 Oh, they sell it all right, now that we know it isn't a little packet of cable oil and we have a correct part number for it !!! ;D |

Title: Re: A potential fix for speedo cable oil leak! Post by LouSiana on 08/23/12 at 14:07:50 Oh-um... I think I get you right now. This part is listed in your 'fiches' but the name is corrupted. Aaargh! hihi Who ever needed 'Cable Oi'l if in case the cable is oil-soaked. That's different here: The seal is not listed, not shown. Just looked in the Motofiches (french-german copies of spare parts) and on CMSL. Not in the tach section, not in the engine case section and also not in the section showing the transmission parts. Lost in translation there, left out here. |

Title: Re: A potential fix for speedo cable oil leak! Post by Savage_Rob on 08/23/12 at 15:34:40 Yeah, I might just have to pick up a spare next time I order something else (because shipping is 3x the cost of the part, more at some sites). I am using my original one and it's 14 years old now. Thanks a lot for identifying this. |

Title: Re: A potential fix for speedo cable oil leak! Post by Oldfeller on 08/23/12 at 16:05:54 I have lost mine twice (taking the tank off to adjust the valves mostly) and had to keep looking way way past $3 worth to find it -- I too will get a spare one as soon as I have an order for something more substantial to cover the shipping charges. |

Title: Re: A potential fix for speedo cable oil leak! Post by greenmonster on 08/24/12 at 15:10:55 Went into the stealership today and ordered it up. I'll let you guys know how it goes. |

Title: Re: A potential fix for speedo cable oil leak! Post by lacon on 08/29/12 at 10:18:52 Also stopped by my local Suzuki dealer today. Not in stock, but no extra charge to have them order one for me. $2.49 + tax. Will be in next week. No rush to install as my rubber washer is holding, but wanted to have the correct seal on hand. |
|
Title: Re: A potential fix for speedo cable oil leak! Post by LouSiana on 08/29/12 at 13:26:44 I have about a dozen Savage-riders in my area, so I added three seals at my last order. Most of the riders I see monthly on our regular's table. Last weekend we had a bigger meeting 80 miles from here. It was overwhelming to see far more than 40 (!!) Savage's on one place, coming from all sides of Germany and two people even from Belgium. Most of the bikes got a bit customized but I still do like that bike when it is all stock equipped. Only very few had complaints about that sealing and I gave them the number which I now know by heart. As I mentioned before, I have not the slightest issue without that sealing in any way. Not a single drop of oil coming out of that port, even when I go on a ride with the speedo cable disconnected, just for testing. But I sure know, some have remarkable leaking problems. I still wonder why... Maybe everyone who has an issue with it should prove the bleeding hose from the cylinder head is not bent or blocked in any way. With a bent hose, blow-by gasses and rising temperatures might press out engine oil wherever it can be done. |

Title: Re: A potential fix for speedo cable oil leak! Post by dcubansavage on 08/03/13 at 10:42:22 Hey Ben I just bought the bonded sealing washer u recommend. Quick question??? Does the metal side of the washer go down against the engine or the rubber side? Tx. |

Title: Re: A potential fix for speedo cable oil leak! Post by Oldfeller on 08/03/13 at 19:45:15 Dude, nobody is using the flat washer trick since we found the correct part number for the rubber lip seal and it only costs $3. But hey, you can use whatever you like, it's your bike. There is an issue with that flat washer trick getting a little bit off center and the steel washer part eating up the shaft, then you got other issues to deal with as no seal is going to seat & seal on an eaten up shaft. Read back over the last page or so, it's all in there. |

Title: Re: A potential fix for speedo cable oil leak! Post by Oldfeller on 08/05/13 at 01:01:59 Many have used the $.89 plain "O" ring trick and had no problems (no shaft damage).

Using steel backed rubber washers CAN do steel on steel damage to the inner flex shaft, after which there is no fixing it other than a new cable. You pick, it's your bike. |

Title: Re: A potential fix for speedo cable oil leak! Post by Jeff71 on 07/25/14 at 09:21:50 What if you remove the cable completely?

Title: Re: A potential fix for speedo cable oil leak! Post by Digger on 08/06/14 at 20:40:04 Well, I guess that the OEM seal just does not work for me (specifics on my Savage are in my signature block). I put a new on on there about 500 miles ago. Just noticed this oil leak: http://i235.photobucket.com/albums/ee201/Digger109/LS650/SpeedoCableLeak-2E.jpeg http://i235.photobucket.com/albums/ee201/Digger109/LS650/SpeedoCableLeak-1E.jpeg Looks like it's back to the o-ring kludge (http://suzukisavage.com/cgi-bin/YaBB.pl?num=1268286763) for me. I'll try to update the above "kludge" thread with specific information (sizing, material) of the o-ring I end up going with. And I had such high hopes.... |

Title: Re: A potential fix for speedo cable oil leak! Post by Dave on 08/07/14 at 03:27:54 It could also be the O-ring on the part that is mounted in the engine block. Mine started leaking earlier this summer. I had a strange once in a while issue with a fine oil drops on the right side of the engine, and it would also get on top of the fuel tank. I could ride for weeks with nothing....and then it would show up - but I could not find the source. Then one day I had a spotless bike and was headed to a show and group ride. I stopped on the way and noticed the oil spray, and I found the speedo drive nut had oil on it....and suddenly I figured out the scenario. When I got on the highway that morning I did a full throttle run through the first 3 gears....and evidently when the crankcase pressure builds under full throttle and high rpms - it can force oil out the speedometer drive. Mine no longer has the cable and is blocked off - but the oil was coming past the O-ring on the piece that holds the drive gear into the case. I fixed that....and now I no longer have a leak. Dave |

Hi Dave, Actually, an oil seal, not an o-ring, is utilized by the factory where the speedometer cable housing screws in to the top of the engine block via the knurled fitting (unless you know of an o-ring below this area that I'm unfamiliar with). Said oil seal is discussed earlier in this thread. My personal history with this seal is detailed here (this is a quote from an earlier post to this current thread): 052826262433410 wrote:
Odd that you mention an o-ring, however, as that is how I generally seal this area (see here (http://suzukisavage.com/cgi-bin/YaBB.pl?num=1268286763)) Jus' clearin' up the terminology...... |

Title: Re: A potential fix for speedo cable oil leak! Post by Dave on 08/07/14 at 09:20:07 Not sure how well this page will show up - but the O-ring is part number 43, and it fits onto the tube #42 that goes into the case to hold the speedometer drive gear. Mine was leaking at this O-ring when the engine was asked to use all 30 HP for a few gears. Dave |

Dave, Thanks for pointing that out....I learned something new! It seems to me that the oil seal mentioned above in this thread would most likely be incapable of stopping a pressurized leak of motor oil past the o-ring (that you pointed out) and onto the exterior of the engine. And, it also seems to me that, even if the o-ring you pointed out was leaking badly, the o-ring that I like to substitute for said oil seal (seen here: http://suzukisavage.com/cgi-bin/YaBB.pl?num=1268286763) WOULD stop any oil from escaping past the knurled fitting at the bottom of the speedometer cable. That being said, I will most likely try to source a suitable o-ring for my kludgy fix tomorrow.....will report. |

Title: Re: A potential fix for speedo cable oil leak! Post by Dave on 08/08/14 at 03:14:07 Digger: I wonder if the cable housing is mostly sealed on both ends, and actuallly becomes slightly pressurized during operation? The seal might just be there to try and keep most the oil down in the crankcase. My speedometer drive is sealed on the top with the knurled nut as I have an electronic speedo. I made a stainless insert to cap off the drive and it is sealed tight with an O-ring....and the oil leak I was experiencing was the #43 O-ring down in the case. It only leaked when I had the engine at full song! Dave |

I saw a previous post where they cut the old cable in order to get the stock "nut" free to use with a rubber stopper. I was looking to do the same as you since I went electrical and by dumb luck I threw a spare axle nut on there and it seems to be a match, M16 if I read correctly elsewhere. Not sure if this is relevant to you anymore but in case anyone else goes looking there you have it. I can't seem to find a reasonably priced acorn nut of that size however. Nathan |

Old thread, first time poster, but could be relevant to someone else. Can anyone answer this? I just bought the OEM part but not sure if the metal side goes up or down against the case. Thanks! |

Title: Re: A potential fix for speedo cable oil leak! Post by batman on 07/01/19 at 19:43:47 Not many have ever though of a copper washer, I use these for the speedo cable and oil drain plug , I anneal the copper washers ,which allows them to be used over and over again. copper being softer than the speedo cable can never damage it. The use of a copper washer on the oil drain plug means it will never be frozen ,it will always be removable even if you torque it down hard ,and it won't leak. |
