4.1 Preparatory Data

Precautions on operation

Do not contaminate braking shoe ad brake disc with oil.

Basic preparatory data

Item	Standard ValueЈЁmmЈ©	Service LimitЈЁmmЈ©
Rear wheel Shimmy	Longitudinal		2.0
Transversal		2.0

 

Tightening torque

Rear shat locknut 100 - 113 NЎ¤m

Rear shock absorber top nut 37 - 44 NЎ¤m

Rear shock absorber bottom nut 37 - 44 NЎ¤m

4.2 Fault Diagnosis

4.2.1 Shimmy Rear Wheel

l Distorted wheel rim

l Worn rear bearing

l Troubled tyre

l Worn or injured swing arm pivot bush

l Improper adjustment of drive chain adjuster

l Unbalance of tyre and wheel

l Tyre pressure is too low

l Bent frame or swing arm

4.2.2 Inflexible Wheel Rotation

l Flexible rear liquid brake plate

l Worn rear bearing

l Too tight drive chain

4.2.3 Soft suspension

l Insecure damping spring with shock

l Incorrect front suspending regulator

l Oil leakage of shock absorber

l Tyre pressure is too low

4.2.4 Hard suspension

l Damage of assembly axle on shock absorber

l Bending shock absorber pipe

l Damage of rear rocking arm pivot bearing

l Bending rear rocking arm pivot bearing

l Incorrect suspending regulator

l Tyre pressure is too high

4.2.5 Operation with one side only or not taking straight line

l Bending rear axle

l Arrangement of axle of both sides/incompetent chain regulator

Rear wheel

4.3.1 Disassembly

Loosen rear axle nut

Disassemble rear axle nut and take down chain from chain wheel seat

Disassemble rear axle

Disassemble rear wheel

 

4.3.2 Inspection

4.3.2.1 Check the bending of axle

Put axle on V-style seat and measure its eccentricity ratio with dial indicator

Use limits: change over 0.2mm

4.3.2.2 Wheel Shimmy Inspection

Rotate the wheel by hands and measure its eccentricity with a dial gauge.

Service limit:

Longitudinal: Replace it when the measured value exceeds 2.0mm.

Transversal: Replace it when the measured value exceeds 2.0mm.

When rear wheel shimmy exceeds service limit, rear wheel bearing is loosened, which results in wobbly rear wheel. Check and replace rear wheel bearing.

 

4.3.3 Installation

Install the rear wheel in the reverse order of removal and tighten the nut.

Rear wheel shaft locknut

Tightening torque: 100-113NЎ¤m

4.4 Rear Shock Absorber

4.4.1 Disassemble rear shock absorber

Disassemble body guard board

Disassemble rear splash guard

Disassemble tool box

Disassemble air filter

Disassemble rear wheel shock absorber fixed bolt

Take down rear shock absorber

 

4.4.2 Rear Shock Absorber Inspection

Visual inspection of shock absorber to check whether there is damage

 

Check the following items:

ЎЄbending or damage of shock absorber pipe

ЎЄout of shape or oil leakage of shock absorber

ЎЄabrasive wear or damage of block rubber

ЎЄdamage of spring

 

Check damage or abrasive wear of other parts

Replace shock absorber if necessary

 

4.4.3 Install Rear Shock Absorber

Install the rear shock absorber in the reverse order of removal.

Install upper locknut and lower mounting bolt on the rear shock absorber

Tighten them to specified torque.

 

Torsion force:

Upper hold-down nut: 37-44NЎ¤m

Bottom hold-down nut: 37-44NЎ¤m

4.5 Rear Swing Arm

4.5.1 Remove Rear Swing Arm

Disassemble chain guard board

Disassemble chain tension wheel and rear axle

Disassemble rear wheel and rear shock absorber

Disassemble rear swing arm installment axle

Take down rear swing arm weld assembly

 

4.5.2 Rear Swing Arm Inspection

Check rear swing arm installation shaft. Rotate the shaft on a flat surface or measure it with a dial gauge. If it is bent, replace it.

* Attention

DonЎЇt attempt to straighten bent shaft.

 

 

Wash in solvent the components for rear swing arm installation shaft.

Check sleeve assembly and intermediate sleeve of rear swing arm.

If they are damaged, replace them.

 

4.6 Drive Chain

4.6.1Ј® Disassembly

Lay motorcycle on the flat ground and fasten

Disassemble shift lever swing arm, left rear cover and drive chain

Disassemble rear wheelЎўchain shield and drive chain

 

4.5.2Ј® Inspection

Wash drive chain and put it into kerosene. Brush dust and then take it out from kerosene and dry it out.

 

Check rattleer1and side panel2. replace drive chain when damaged or abrased.

 

Lubricate drive chain. Buy it from store

Check drive chain. Wash, lubricate and replace it if it is hard.

 

 

 

 

Check drive chain and driven chain wheel. Replace chain wheel when 1/4 gear teeth are worn. Replace it when gear teeth is bending.

 

Check wheel axle. Replace when there is bearing gap in hub or unbalance of rotation. Check oil seal and replace when there is abrasive wear or damage.
