Checking Wheel Alignment
●Check whether the position of the concave scale line
[B] on the right chain adjuster [A] on the rear swing
arm [C] is the same as that of concave scale line on the
left chain adjuster.
★
If they are not aligned, adjust the slackness of drive
chain and align the wheel alignment (see “Adjusting
Slackness of Drive Chain”).
○Check whether the wheel alignment is accurate
with the ruler or rope.
If the wheels are not aligned, the wheels will
be worn out abnormally and dangers may be
caused during riding.
Checking Wear of Drive Chain
●Remove the chain guard (see “Disassembling Drive
Chain” in “Final Drive Mechanism” chapter).
●Rotate the rear wheel and check whether there are
damaged rollers, loose cotter pins and chain meshes.
★
If any abnormal situation is found, replace the drive
chain.
★If the drive chain looks dry, add the lubricant.
●Hang a 6kg
weight on the drive chain to tighten the
drive chain.
●Measure the length of the 20 links [B] (from the
center of the first cotter pin to the center of the 21
st
cotter pin) of the drive chain of the straight part [C]. As
the drive chain is
worn unevenly, the measurement
shall be carried out in several different parts.
★
If any measured value exceeds the use limit, the
drive chain needs to be replaced. Replace the front and
rear sprockets simultaneously.
Length of 20 chain meshes of drive chain
Standard: 254 -254.7 mm
Use limit: 259.5 mm
If the wear of drive chain exceeds the use limit,
the drive chain must be replaced, otherwise
dangers may be caused during riding. If the drive
chain is broken or falls off from the sprocket, the
spr
ocket of engine will be tripped or the rear
wheel will be locked, which will cause serious
damage to the motorcycle and make it be out of
control.
To ensure safety, the standard drive chain
must be used. The standard drive chain is a chain
without meshes w
hich cannot be cut off during
installation.
Standard Drive Chain
Model: 428HG
Number of chain meshes: 116
