Bevel Gear Backlash Procedure
(MAG Side Crankcase)
Use the following course of calculation to deter-
mine the theoretical thickness
D of thrust washer
no. 35 on MAG side crankcase:
D = B - C - A
B = Distance between the thrust surface of bevel
gear and the theoretical center of its taper.
This is defined by manufacturer and written
on the bevel gear shaft.
NOTE: Bevel gear reference number is a value
between - 10 and + 10.

A = 2 mm (.0787 in) nominal thickness of axial
needle bearing no. 36 .
When all the measurements are taken, calculate
the theoretical thickness
D of thrust washer using
the formula ( D = B - C - A ).
Take the obtained theoretical thrust washer thick-
ness
D and choose the proper thrust washer num-
ber E according to the following table.

Example
Take the reference number on the bevel gear
shaft: - 3.
B = (- 3/100) + 37.8
B = 37.77
