SELECTING THE PINION SHIMS
NOTE:
Find the shim thickness (T3) by selecting
shims until the specified value (M0) is
obtained with the special tool.
1. Measure:
•
Specified measurement (M)
Out of specified value (M0) →
Adjust.
Specified value (M0) =
0.3 + P/100 mm
Measuring steps
(1) Calculate the specified value (M0).
NOTE:
• "P" is the deviation of the lower case
dimension from standard. It is stamped
on the trim tab mounting surface of the
lower case in 0.01mm units. If the "P"
mark is missing or unreadable, assume
a "P" value of "0", and check the back-
lash when the unit is assembled.
• If the "P" mark is negative (-), then sub-
tract the "P" value from the measure-
ment.
Example:
If "P" is "+5", then:
M = 0.3 + (+5)/100 mm
= 0.3 + 0.05 mm
= 0.35 mm (0.014 in)
If "P" is "-3", then:
M = 0.3 + (-3)/100 mm
= 0.3 - 0.03 mm
= 0.27 mm (0.011 in)
