Pete.M Posted July 14, 2011 Report Share Posted July 14, 2011 I've recently fitted a chain tensioner but the chain still occasionally jumps. Is it possible to put the chain under too much tension? Everything seems aligned ok. Cheers. Quote Link to comment Share on other sites More sharing options...
Mark W Posted July 14, 2011 Report Share Posted July 14, 2011 Photos would definitely help. Is it a single wheeled tensioner, or a double wheeled tensioner? If it's a single wheeled one then it's most likely to be a lack of chain-wrap around your rear sprocket, so when you get the power down it'll just jump over the teeth of your rear sprocket.

I can get pictures up tomorrow, but you could well be right there. I bought a double wheeled tensioner that is probably too long for my size of sprocket but it still provides half decent chain-wrap. I regret buying that tensioner, it was a bugger to fit in the first place. Cheers. Quote Link to comment Share on other sites More sharing options...
BradJohnson Posted July 15, 2011 Report Share Posted July 15, 2011 I had the same problem, the tensioner wasn't giving enough tension. Quote Link to comment Share on other sites More sharing options...
Pete.M Posted July 15, 2011 Author Report Share Posted July 15, 2011 Sorry for the bad picture, too lazy to take my bike outside. There certainly isn't an ideal amount of chain-wrap, and I clearly bought the wrong size of tensioner. What a dummy. Is the skipping going to cause damage? Because right now I think i'd rather continue like this than spend more money. Cheers. I had the same problem, the tensioner wasn't giving enough tension. Interesting, mine is under a lot of tension at the moment but it might be worth a try. Quote Link to comment Share on other sites More sharing options...
ezgonzo Posted July 15, 2011 Report Share Posted July 15, 2011 i'm guessing your sprocket is a 16t if so then your tensioner is fine, like other's have mentioned you need to adjust the tensioner so there's more chain wrap and a bit more tension aswell, you may need to shorten your chain aswell. i've edited your pic to show what i mean, as shown in the pic you want to have the arm as close to the drop out as possible while @ the same time pulling the pulley's near level with the arm aswell in order to increase the tension, hope that helps and makes sense .

Pete.M Posted July 15, 2011 Author Report Share Posted July 15, 2011 (edited) Cheers. That is what I thought needed doing. Only thing is I can't move the arm upwards because it has some restricting post thing. Is this something that other people have managed to remove? Here it is: Edited July 15, 2011 by Pete.M Quote Link to comment Share on other sites More sharing options...
ogre Posted July 16, 2011 Report Share Posted July 16, 2011 you'll want to remove the limiting pin (the one that stops the tensioner swinging past a certain point on the hanger) mole grips are your friend... then you can ride it up and have awesome tension...

No dont do that just take 2 links out of the chain, if you take the pin out the spring wont work. Quote Link to comment Share on other sites More sharing options...
Pete.M Posted July 17, 2011 Author Report Share Posted July 17, 2011 But then I couldn't achieve more chain wrap? It seems to be working fine at the moment without the pin as the spring is still under tension. Quote Link to comment Share on other sites More sharing options...
