Title: Loosen pulley bolt? Post by RobSchneider on 06/20/13 at 13:46:25 Finally time to remove the engine from the frame to place the helicoils in the cilinderhead. Have all the mountingbolts out, but now I'm stuck with the beltpulley. There is no movement at all, and the rearwheel is keep pushing forward. Also I thought the tension uou apply on the pulley when loosenng thebolt is bad for the belt itself? The'tooth' can break off or something? I already thought of taking the sidecover on the beltside off, butI guess there is oil behind it? Since it doesn't run I wasn't able to take out the oil... Anybody can confirm that here is oil behind it? Otherwise I can remove it, leave the beltpulley and slide the belt off(it now can't get between the pulley and cover) Thanks in advance for reactions! |

Title: Re: Loosen pulley bolt? Post by RobSchneider on 06/20/13 at 14:21:24 I meant the small pulley next to the engine, not the big one at the rear wheel. Can't seem to get any tension on it, since the wheel is moving forward when trying to losen the bolt... |

Title: Re: Loosen pulley bolt? Post by paulmarshall on 06/20/13 at 14:30:24 so do I. For whatever reason either no leverage or just too tight I needed to use a air ratchet to loosen it. At my local bike shop. Try applying rear break when doing it. Put it in gear. |

Title: Re: Loosen pulley bolt? Post by verslagen1 on 06/20/13 at 15:03:05 now the fun begins front wheel against a wall in a big gear apply the rear brake and a brick in front of the tire you'll either break it loose or spit the brick out the back the slick garage floor offerred no traction so I added a strap around the tire to the frame. another way is to put a socket between the pulley and belt and let it rotate to hit the engine casing. the socket should have straight sides and be small enough to nest in the pulley teeth. Around a 1/4" drive, 9mm socket. I don't have an impact driver, and in this case wouldn't use it. BTW, unless you're transferring the belt to anouther engine, leave it be. The engine will come out with it on. |

Title: Re: Loosen pulley bolt? Post by shovelbum87 on 06/20/13 at 15:08:12 If you put a ratched on it with a long pipe you can get it loose while standing on the right side with your foot on the brake pedal. Ive done it a couple times now, I use a load bar from a flat bed tractor trailer its a 4 foot long hollow pipe. Im not a very big girl but I can do it with no help at all. |

Title: Re: Loosen pulley bolt? Post by gizzo on 06/20/13 at 15:16:53 This is a trick I've used loads of times: If you have a side cover off and can see some gears (starter gears maybe) you can stuff a rag between two of the gears and then try the nut. The rag is usually enough to jam the engine and doesn't damage the gears. Occasionally the nut can be tight enough to drag the rag through but it works surprisingly often. You'll have to decide for yourself whether you think this will put too much load on the engine cases. But like I said, It's worked for me many times, including on motorcycles. A nut gun would be a better option though. My 2c, YMMV etc. s |

Title: Re: Loosen pulley bolt? Post by RobSchneider on 06/20/13 at 22:32:07 Thank you for the answers guys, the rearbrake is not an option because the pedal is already off the bike. I'm not getting it in gear either, looks like it's stuk (or do I need to push more? |

Title: Re: Loosen pulley bolt? Post by Serowbot on 06/20/13 at 23:20:51 I strapped the rear wheel to a post with a ratchet tiedown... I used to... I got an impact wrench now... :-?... |

Title: Re: Loosen pulley bolt? Post by RobSchneider on 06/21/13 at 11:47:54 Tried it again, but it is too tight! I had the torquewrench on 180 (!) and it still doesn't come of, every time I give more power the backwheel slips, no matter whats in the way of it... Is there any other way to take it off or does anyone has a better idea to do it? |

Title: Re: Loosen pulley bolt? Post by Serowbot on 06/21/13 at 12:16:25 You really need an impact wrench... if you can get it to a tire shop, or anywhere with one,... they'll have it off in a second... (probably no charge, or very little)... (bring your socket with you) .. or, you can get a cheapy, electric impact wrench from Harbor Freight for $50 or $60... |

Have tried two impactwrenches, both without result... Tried to heaten op the bolt and screw it off, but no movement at all... Guess I have to keep trying until it comes loose......... |

Title: Re: Loosen pulley bolt? Post by Digger on 06/24/13 at 21:15:31 I'll mention this just to fill a square: Ain't there a bent washer holding that nut on there? |

Title: Re: Loosen pulley bolt? Post by WD on 06/24/13 at 21:20:39 Is that one reverse threaded by any chance? Never pulled one on a Savage, but several of my left side drive bikes have the crank nut and front sprocket assembly held on with reverse threads... |

Yep, hope he found it. Quote:
pretty sure we've established it has regular threads. sitting in seat, push forward to loosen, pull back to tighten. |

Title: Re: Loosen pulley bolt? Post by Serowbot on 06/24/13 at 22:07:15 It's righty tighty/lefty loosy for sure... Put an impact wrench on there, and just let it hammer away.... (nothing is gonna' do any better)... it'll come loose in a minute... I just had a CV axle nut on a car, with one of those hammer over nuts, that was so tight I couldn't get a chisel in there to pry it out... about 30 seconds with an electric impact wrench broke it loose... (had to buy a new nut...Lol)... I just kept hitting it with 10 second bursts 'till it let go... |

Well, I didn't found it, but I did looked for it cause the manual says it's there. The screw itself looks damaged on one side, I'll make a photo when I can. Cannot imagine that the 'damaging' is the bend washer... |

Title: Re: Loosen pulley bolt? Post by justin_o_guy2 on 06/25/13 at 14:03:19 youll have a time gettin a sochet all the way down if that washer is on there. one side is supposed to be bent out & folded up on one of the flats of the nut to lock it in place. |

Title: Re: Loosen pulley bolt? Post by RobSchneider on 06/26/13 at 01:04:23 I feel like such an idiot... You guys are absolutely right, there is a bend washer there. I thought it was a bolt like this: http://www.japparts.nl/images/kawaspecial/b_5032.jpg Indeed there is one side folded (see photo) I tried to bend it back yesterday, but so far no luck with loosen the bolt. Am trying again tonight or tomorrow... hope it works! by the way the socket fits over the bolt, thats no problem. Can anybody explain why the bend washer is capable of holding it all tight? |

The inside of the washer is notched and locks onto the splines on the shaft, and that keeps the washer from turning. The bend along the side of the nut then locks the nut in place. |

Title: Re: Loosen pulley bolt? Post by RobSchneider on 06/28/13 at 13:41:35 YIIHHAAAAAAA! Got it! had heaten it up, and impact wrenched it a couple times the past days, and today finally result! |

Title: Re: Loosen pulley bolt? Post by RobSchneider on 07/03/13 at 01:18:07 Ok, got the engine out of the frame, and the side cover + topcover off. I want to line up the small grooves on the camshaft with the cilinder, but the chain is not moving, how can I arrange that before I take the chain off. |

You need to rotate the crank slightly to move the chain. More importantly you want to place the crank so the piston is at top dead center.....then take note of where that small groove/notch is. On mine the cam notch did not line up perfectly......so before you take your apart see how it lines up and put it back there when you put it together again. |

So how do I move the crank, which one is that? (sorry dutch is my normal language, so some things are not very clear to me in English) Do you perhaps have a photo somewhere? |

Title: Re: Loosen pulley bolt? Post by Serowbot on 07/03/13 at 08:34:26 Remove the spark plug, to make turning easy... Then use a 17mm wrench on the nut under the timing inspection cover... left side engine case.... (crank counter-clockwise to reach TDC.... http://suzukisavage.com/cgi-bin/YaBB.pl?num=1278347767 |

Huh? I already took off the topcover from the engine... |

Title: Re: Loosen pulley bolt? Post by Dave on 07/03/13 at 11:17:54 I think maybe there is some confusion. The crankshaft is the part of the engine that rotates and has an offset pin and bearing in the center porton that the rod and piston are connected to. The head cover (top cover) bolts on top of the cylinder head, and it also has the rocker arms installed in it and it acts as the upper bearing surface for the camshaft. The Cylinder head bolts on top of the cylinder and has the valves, intake and exhaust ports cast into it. The cylinder head has the spark plug threaded into it. If you remove the spark plug from the cylinder head, it is easier to turn the crankshaft with a 17mm socket on the left side of the crank. If you have the clutch cover off, you can also use the right side of the crankshaft to rotate the crankshaft which will move the cam chain and camshaft. Do you have a workshop manual? What are you up to? We started at the belt pulley in this thread, and now the engine is out and the head cover is off! |

Thank you for the explanation, I do have a workshop manual, but it wasn't clear how to do it. I'm taking the cilinderhead off to place helicoils in the threads underneath. The previous owner put too much tension on those threads and damaged them. As a result I had some big oil leakage when I started the bike. (I did the plug-cap sealant before, didn't help) So thats why I had to take of the belt pulley, since I have to take the engine out for the placement of the helicoils. I'm going to read this again tomorrow, and trying to fully understand what I have to do. |
