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) =
0.30 + 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 0.01-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 "P" is "+8", then
M0 = 0.30 + (+8)/100 mm
= 0.30 + 0.08 mm
= 0.38 mm
If "P" is "–3", then
M0 = 0.30 + (–3)/100 mm
= 0.30 – 0.03 mm
= 0.27 mm
