p_ruskin Posted February 2, 2011 Report Share Posted February 2, 2011 I have some TNN clamps on my Echo, they don't have cylinder washers. Every time I set up my pads the cylinders slowly push themselves outwards so the lever comes closer and closer to the bar. The clamps are tightened fully but they wont stay put, every 5 mins light riding they manage to move out 4-5mm. Any ideas on why they wont clamp properly?

Sam T Posted February 2, 2011 Report Share Posted February 2, 2011 Can be down to your bolts being too long if your running a booster. Quote Link to comment Share on other sites More sharing options...
p_ruskin Posted February 2, 2011 Author Report Share Posted February 2, 2011 Ahh! could be the problem! don't know how I would go about fixing this though as I need a booster but cant fit it with shorter bolts. Quote Link to comment Share on other sites More sharing options...

To make the bolt shorter you can use the washer out of a chain take apart the chain like in the pic If it's not the bolts then get a can cut a strip off and put it around the cylinder should do the trick!

Jon Alty Posted February 2, 2011 Report Share Posted February 2, 2011 I thought TNN clamps used no washers, just clamped straight onto the cyclinders? Sorry if im wrong Quote Link to comment Share on other sites More sharing options...
j-bonham@hotmail.com Posted February 2, 2011 Report Share Posted February 2, 2011 Defo misundestood something there mate... They do not have cylinder washers, but his are not clamping the cylinder enough. so could be down to bolts being too long. So a washer on the bolt would make it shorter.

Even read like twice to make sure i wasnt being a retard, read again after u posted and blatently says hes not using washers :$. I would personally use a washer and see if it sorts it, then if it does, instead of keeping the washers, use a hacksaw and chop a bit off each bolt.

Shaun H Posted February 3, 2011 Report Share Posted February 3, 2011 I have to overtighten mine and actually deform them to get them to work. To this day I still don't understand how they are supposed to clamp effectively. Quote Link to comment Share on other sites More sharing options...
Luke Dunstan Posted February 3, 2011 Report Share Posted February 3, 2011 I'm using the same frame and bolts as you, and put a trialtech 2-bolt booster on this morning, used 2 little washers and it fits perfectly. Hope this helps bud. Quote Link to comment Share on other sites More sharing options...
