MAINTENANCE AND ADJUSTMENT
j
•
Tighten both chain adjuster locknuts.
•
Torque the axle nut to the specified torque.
Rear Axle Nut Tightening Torque
79 N·m (8.1 kgf·m, 58 ft·lb)
•
Rotate the wheel, measure the chain slack again
at the tightest position, and readjust it if necessary.
•
Install a new cotter pin through the axle, and
spread its ends.
WARNING
A loose axle nut can lead to an accident re-
sulting in serious injury or death.
Tighten
the axle nut to the proper torque and install
a new cotter pin.
•
Check the rear brake effect.
Chain Wear Inspection
When the chain has reached its wear limit (i.e.,
when it has stretched by 2% of its original length),
it is no longer safe for use and should be replaced.
Since it is impractical to measure the entire length of
the chain, determine the degree of wear by measur-
ing a 20-link section of the chain.
•
Tighten the chain either by using the chain ad-
justers or by hanging a 10 kg (20 lb) weight on the
chain.
•
Measure the 20-link section on a straight part of
the chain from the center of the 1st pin to the cen-
ter of the 21st pin. If the length exceeds the ser-
vice limit, the chain should be replaced.
Since
overworn sprockets will cause a new chain to wear
faster, inspect both the engine and rear sprockets
whenever the chain is replaced, and replace them
if necessary.
