(A) Pinion height adjusting shim
(2) Measure the clearance N between the end
of ST2 and end surface of ST1 by using a thick-
ness gauge.
NOTE:
Make sure there is no clearance between the case
and ST2.

(3) Obtain the thickness of pinion height adjust-
ing shim to be inserted from the following formu-
la, and replace the temporarily installed shim
with this one.
T = To + N − (H x 0.01) − 0.20 mm (0.0079 in)
NOTE:
Use copies of this page.
T Thickness of shim temporarily inserted
mm (in)
To Thickness of pinion height adjusting
shim mm (in)
N Reading of thickness gauge mm (in)
H Figure marked on drive pinion head

(Example of calculation)
To = 2.20 + 1.20 = 3.40 mm
N = 0.23 mm H = + 1,
T = 3.40 + 0.23 − 0.01 − 0.20 = 3.42
Result: Thickness = 3.42 mm
