Chain Tensioner

Featured Replies

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

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)

what he said :icon_salut:

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.

The spring should keep it up, requires a bit of effort, but not hernia inducing.

OK, mine sounds OK... just need to replace the spring.
