(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.
Example:
If M3 is “46.85 mm”, M4 is “15.12 mm” and
P is “–5”, then
T3 = 62.5 + (–5)/100 – 46.85 – 15.12 mm
= 62.5 – 0.05 – 46.85 – 15.12 mm
= 0.48 mm
(6) Select the pinion shim(s) (T3).
Pinion shim thickness (T3) =
62.5 + P/100 – M3 – M4
