(5) Calculate the pinion shim thickness
(T3).
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 backlash
when the unit is assembled.
• If the “P” mark is negative (–), then add
the “P” value to the measurement.
Example:
If M3 is “46.85 mm”, M4 is “32.52 mm” and
P is “-5”, then
T3 = 80.0 + (–5)/100 – 46.85 – 32.52 mm
= 80.0 – 0.05 – 46.85 – 32.52 mm
= 0.58 mm
(6) Select the pinion shim(s) (T3).
Pinion shim thickness (T3) =
80.0 + P/100 – M3 – M4
