(4) Calculate the pinion shim thickness
(T3).
Pinion shim thickness (T3) =
12.00 – M3 – P/100
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 "11.70 mm" and P is "+8", then
T3 = 12.00 – 11.70 – (+8)/100 mm
= 0.30 – 0.08 mm
= 0.22 mm
If M3 is "11.70 mm" and P is "–3", then
T3 = 12.00 – 11.70 – (–3)/100 mm
= 0.30 + 0.03 mm
= 0.33 mm
(5) Select the pinion shim(s) (T3).
