Measure shim on MAG side:
NOTE: Clean mating surface of crankcase before
measurement. Refer to crankcase assembly pro-
cedure.
• A = 2 mm (.0787 in) nominal thickness of axial
needle bearing no. 20 .
• B = Distance between butting face and theoret-
ical center of bevel gear taper. K is defined by
manufacturer and written on surface of bevel
gear PTO end.
Use following course of calculation to find out val-
ue
B .
B = (K/100) + 37.8
NOTE: Value K is a number between - 10 and + 10
and equals the (±) deviation to the nominal value
of 37.8 mm (1.488 in) in hundreth of a millimeter.
For example, number K = - 3 equals - 0.03 mm
(- 0.0012 in) to the nominal value of 37.8 mm.
B = (-3/100) + 37.8 = 37.77
1. Bevel gear
2. Area of written number K to find out value
B
• C = Distance between butting face (MAG side)
to mating surface of crankcase MAG.
1. Depth gauge — measurement C
2. Butting face inside of crankcase MAG
• D = Theoretical shim thickness.
• E = Shim selected in accordance with D .
Use following course of calculation to get the the-
oretical thickness
D for washer no. 19 .
D = B - C - A
NOTE: Take theoretical value D and choose shim
E (MAG side shim) from the below table.
NOTE: For example, if the measured thickness is
1.53 mm (.0602 in), choose the shim 150. The shim
number 150 represents a value equal at 1.50 mm
(.0591 in).
