1) Measure length "H", which is from transmission
case and oil pump cover mating surface to ball
bearing edge.
(A) Transmission case
(B) Ball bearing
(C) Driven gear assembly
2) Using the following equation, calculate the
washer thickness of driven gear assembly.
T=H – {5.8 ± 0.05 mm (0.23 ± 0.002 in)} – {0.1 to
0.3 mm (0.0039 to 0.0118 in)}
t Thickness of washer
H Length from transmission case and
oil pump cover mating surface to ball
bearing edge
5.8 ± 0.05 mm Thickness of collar
(0.23 ± 0.002 in)
0.1 to 0.3 mm Backlash specification at axial direc-
(0.0039 to 0.0118 in) tion of driven gear assembly
3) Select 0 to 3 washers from the following table to
adjust backlash closest to specification.
Backlash specification at axial direction of driv-
en gear assembly:
