Measure drive chain slack
It is imperative to replace the drive chain when the chain stretch exceeds 5% of its original length.
The best way to measure the chain is by measuring the length of 20 links and comparing this value to a reference.
1.
Tighten the
chain adjusters
to move the rear axle rearward until the
drive chain
is
tight
(no slack).
2.
Measure the length of 20 links from the 1
st
pin of the first link to the second pin of the 20
th
link. On the straight
part of the chain from pin center of the first pin to pin center of the 21
st
pin. If your measurement exceeds the
service limit indicated in the table below, then it is time to replace the chain!
Control of parts associated with the chain
1.
Examine the front and rear sprockets spacing as well. If the chain is worn out, then replace the
sprockets as well.
2.
Rotate the rear wheel to also inspect the drive chain for damaged rollers for wear. If there is any
irregularity, replace the drive chain.
3.
Lubricate the chain thoroughly using the recommended
MOTUL
CHAIN OFF-ROAD grease.
