SHIMMING
(4) Calculate the pinion gear shim thick-
ness (T3).
Pinion gear shim thickness (T3) =
M - 27 mm - P/100 mm
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 0.01 mm 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 add
the "P" value to the measurement.
Example:
If M is "28.30 mm" and "P" is "+5", then:
T3 = 28.30 mm - 27 mm - (+5)/100 mm
= 1.3 mm - 0.05 mm
= 1.25 mm (0.049 in)
If M is "28.24 mm" and "P" is "-3", then:
T3 = 28.24 mm - 27 mm - (-3)/100 mm
= 1.24 mm + 0.03 mm
= 1.27 mm (0.05 in)
(5) Select the pinion gear shim(s) (T3).
