5. Select Washer D
When replacing left crankcase forward gear,
reverse gear, rear cover and output shaft, washer
of output shaft needed to be adjusled.
D
1) Calculate the washer thickness of output shaft
by following formula
Washer thickness of output gear:
d + j - e - B-k-1-0.25
D
=
d
is the value engraved on left crandcase
j
is the value engraved on rear cover
e
is the bearing (at output gear) thickness
¡°1 3 . 0 0 ¡±
¡° k¡±is the value engraved on forward gear
¡° l¡±is the value engraved on output shaft
2) For example:
¡¤ If¡°0.97¡±is engraved on rear cover
¡¤ ¡ °110.05¡±is engraved on left crankcase
¡¤ ¡ °14.4¡±is engraved on forward gear
¡¤ ¡ °80.45¡±is engraved on output shaft
¡¤ So the washer thickness is:
D =110.05-0.97-13.00-0.50-14.4-80.45-
0.25=2.42mm
