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) =
1.00 + P/100 mm
Å Except for B115
ı For B115
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.
• If the "P" mark is negative (–), then sub-
tract the "P" value from the measure-
ment.
Example:
If "P" is "+5", then
M0 = 1.00 + (+5)/100 mm
= 1.00 + 0.05 mm
= 1.05 mm
If "P" is "–3", then
M0 = 1.00 + (–3)/100 mm
= 1.00 – 0.03 mm
= 0.97 mm
