Rear Sprocket Movement

Post by mxj560 » Tue Aug 24, 2010 7:50 pm

Hi guys

My L2 recently developed a strange knocking noise coming from the front sprocket.

I have replaced the clip that sits on top of the front sprocket, cleaned everything up, including the chain, checked for wear and tight spots etc. The only issue remainign is that thre is movement in the rear sprocket.

First off, should the rear sprocket move at all? If so, roughly how much. At the moment mine can move both clockwise and anti-clockwise about 2-3 mm, and generally feels lose.

Secondly, will chaging the cushdrive fix this if it's not normal?

Am hoping that i can stop the knocking by just giving the final drive a bit of TLC.

Thanks for the help

Sorry to pick up on an old thread but dont waste your money, superglue some old bike innertube to the cushdrive if there is only a couple of mm play

It will as a temporary fix, I did it with mine. Ideally u replace the lot because the cush drive doesn't wear, it get compacted by the constant acceleration on deceleration. I did buy a new one once but I forget how much it was.

Easy

Wheel out
remove sprocket carrier from wheel....it just pulls off

replace cush drive rubbers with new ones

refit sprocket carrier

refit wheel

The sprocket carrier might be a tight fit in the new rubbers.................A little spray with polish........I used Mister Sheen................maybe a silicon based spary polish would be good too and the carrier slips in nicely
