Measure shim on PTO side:
NOTE:
Clean mating surfaces of crankcase before
measurement. Refer to crankcase assembly pro-
cedure.
•
F
= Distance between mating surface (crank-
case PTO) to ball bearing inner race.
1. Ball bearing inner race
2. Mating surface of crankcase PTO
3. Depth gauge
•
G
= Distance between mating surface of crank-
case MAG and butting face.
1. Butting surface
•
H
= Distance between butting faces of bevel gear
shaft.
•
I
= Theoretical shim thickness.
•
J
= Shim selected in accordance with
I
.
Use following course of calculation to get the the-
oretical thickness I for washer
no. 27
.
I = F + G - H - A - E
NOTE:
Take theoretical value
I
and choose shim
J
(PTO side shim) from the below table
.
NOTE:
For example, if the measured thickness is
1.53 mm (.0602 in), choose the shim 150.
NOTE:
Bevel gear axial clearance of 0.02 to 0.11 mm
(.00079 to .00433 in) is included in the above table.
