5. Calculate the lower case standard(P/100).
S69j6555
NOTE:
• "P" A stamped on the trim tab mounting face
refers to the deviation of the lower case di-
mension from the standard. The numeral is
in 1/100mm.
• If the numeral is unknown, assume that “P”
is zero, and check the backlash when the unit
is assembled. Readjustment shall be wade
if the measured backlash is out of specifica-
tion.
6. Calculate the pinion shim thickness.
S69j6565
Calculation formula:
Pinion shim thickness
(T3) = 80.00 + P/100 - M3 - M4
Example:
If "M3"= 46.85, "M4"= 32.52, and "P"= –5,
then :
T3 = 80.00 + (–5/100) – 46.85 – 32.52
= 80.00 – 0.05 – 46.85 – 32.52
= 0.58
7. Select the pinion shim(s) as follows.
Example:
If "T3" is 0.58mm, then the pinion shim is
0.55 mm.
If "T3" is 0.70mm, then the pinion shim is
0.68 mm.
Selecting the reverse gear shims
NOTE:
Obtain the reverse gear shim thickness (T1)
by using the specified measurement(s) and the
calculation formula.
Calculation formula:
Reverse gear shim thickness
(T1) = 29.10 + F/100 - M1
1. Measure the roller bearing 1 and the thrust
bearing 2 height (M1).
