¡¤ When changing the crankcase or output gear,
adjust output gear washer
1) Calculate the washer thickness of output gear
hy following formula¡°A¡± :
Washer thickness of output gear:
A= a - b
a
=Theory installing distance 42 of output gear
adds the value engraved on the output gear.
b is the value engraved on crankcase.
Caution
All the unit about the value is mm.
2) For example:
If¡°+0.02¡± is engraved on the output gear.
a
that is : =42+0.02=42.02
If¡° 41.45¡± is engraved on the left crankcase
So the washer thickness is :
A=42.02-41.45=0.57mm
