Title: Cam chain/tensioner data point Post by youzguyz on 09/23/07 at 16:04:35 2002 Savage at 9000 miles. Tensioner 15mm out. Still room before the 18mm "max" point. Ruler is hard to see.. sorry. http://w2.bikepics.com/pics/2007%5C09%5C23%5Cbikepics-1033883-800.jpg VerSlavy in place. Barely got it in using the 2nd hole, but now I have full range of the tensioner. http://w2.bikepics.com/pics/2007%5C09%5C23%5Cbikepics-1033886-800.jpg For those of you using the old gasket, here are some pictures of a new gasket to show you were the sealant goes. (I couldn't save my old gasket, so I'm glad I had a new one) http://w2.bikepics.com/pics/2007%5C09%5C23%5Cbikepics-1033888-800.jpg http://w2.bikepics.com/pics/2007%5C09%5C23%5Cbikepics-1033887-800.jpg |

Title: Re: Cam chain/tensioner data point Post by verslagen1 on 09/23/07 at 17:40:32 Thanks for the pict's YG I'd recommend the stock hole. You may prefer not to be in here for another 10k miles but I think you're going to get accelerated wear. With the stock hole it may go another 10k before you have an issue. I'm thinking that stock extention brand new will be somewhere between 8 and 10mm out. So at 15mm, you have used a little more than half your life on the chain. And this is with the higher spring tension at it's most compressed state. I'd expect that your plunger will need a reset at 15k miles. But, resetting it now, you may need to replace the guides and chain at 18k. Your call, but I'd put it in the stock hole and check it in 5k. Or wait for it to get noisey. Remember, you don't have to worry about blowing up on you. It will bottom out, the chain will get loose and noisey. Even bottomed out it will last a long time before the chain will be loose enough to skip a tooth if you can stand the noise that long. ;D |

Title: Re: Cam chain/tensioner data point Post by youzguyz on 09/24/07 at 07:29:32 oh crud. I didn't even think about what it would be after someone did a cam chain change out. From what you said, and from looking around, it is 8 to 10mm. Any other thoughts by any other guru's or those with more Savage Savy then myself? Is the extra spring compression going to put sufficient extra strain on the guides and/or cam chain to justify going back in and moving it back to the stock hole? |

More like "chicken little". :D Me thinks I will take the old tensioner and do some measurements of spring tension over the range then try to decide based on that. Will still be a wild guess, but one with info behind it. Which assumes that the spring in the old tensioner is that same as the one in the new one, etc, etc. After that I will be sending the old tensioner to verslagen1 to be modified for the next member in need. |

Title: Re: Cam chain/tensioner data point Post by verslagen1 on 09/24/07 at 14:29:17 Brand new install, verslavy with old style spring and new rear 'tensioner' guide, my plunger extended 5mm. 1k later, it was 6mm. 2k later, it was 6.7mm further reports to follow... toot squeak, or whatever the he77 hamsters say ;D My advice, 1st hole until you need it to give you the most out of you system. |

Title: Re: Cam chain/tensioner data point Post by justin_o_guy2 on 09/24/07 at 15:35:11 Will still be a wild guess, but one with info behind it. I call that the S.W.A.G. method. That's the Scientific Wild ANALytical? Guess... |

Title: Re: Cam chain/tensioner data point Post by youzguyz on 09/25/07 at 06:05:42 After doing as good as I could with a spring scale, marks on the tensioner, and shaky hands, here are the results: (eye on scale and measure right before it "clicked" and landed at the mm mark indicated) 0 mm = 7 1/4 pounds 5 mm = 6 1/4 pounds 10 mm = 4 3/4 pounds 15 mm = 3 1/4 pounds It looks like I'll be opening it up to put it back in the 1st hole again. At least I know what to expect now, and the gasket should still be fairly flexible and easy to save. |

Title: Re: Cam chain/tensioner data point Post by Savage_Rob on 09/25/07 at 09:37:42 Mine only had less than 2mm before the keeper pin would hit it's stop at the end of the slot, which is why I reset it and used the 2nd hole. I'll just keep it the way it is now, get one of the new special run chains and set it aside for the eventual change. FYI on the new chains: For those of you who don't look at the Marketplace very often, go check it out and place your orders now. |
