1) Calculate the washer thickness of forward
gear by following formula.
Washer thickness of forward gear:
d - c - e - f
B
=

forward gear adds value engraved on for-
ward gear.
For example:
If¡°d=110.08¡±is engraved on left
crankcase, ¡° c=59.02¡±
If¡°+0.02¡± is engraved on the for-
ward gear,
=37.5+0.02=37.52

So the washer thickness is :
B
=110.08-59.02-13.00-37.52=0.54mm
