upinthehills Posted February 7, 2012 Share Posted February 7, 2012 I have a 4RT and the bike and trialing are new to me. I have noted that the chain tensioner on the left swinging arm has alot of play. Would anyone be able to tell me the correct description for this and what I need to order to sort the problem. The arm itself seems fine, it just the bush/bearing which seems to have failed. cheers ali Quote Link to comment Share on other sites More sharing options...
clay Posted February 7, 2012 Share Posted February 7, 2012 Pretty sure it the same as a 315r, remove tensioner give the two bushs a good soaking with wd40, Gently tap them out with a slightly bigger socket, replace with new,, check tensioner shaft for wear, and replace if worn,, (that should remove all side play) Quote Link to comment Share on other sites More sharing options...

sharkbait Posted February 7, 2012 Share Posted February 7, 2012 what he said Guys how easy to move should the tensioner be? Just noticed mine has lost its spring but the tensioner (which is fairly new) doesn't move that easily - certainly doesn't drop down on it's own without the spring.

b40rt Posted February 7, 2012 Share Posted February 7, 2012 The spring should keep it up, requires a bit of effort, but not hernia inducing. Quote Link to comment Share on other sites More sharing options...
