FINAL DRIVE GEAR AND DRIVE SHAFT
*********************************
Shim selection steps:
To find ring gear shim thickness “B”, use
the following formula.
c= The stamped number on the final gear
case is either added to or subtracted
from “42”.
d= The stamped number on outside of ring
gear bearing housing and added to “2”.
e= The stamped number on inside of ring
gear either added to or subtracted from
“33”.
f= Bearing thickness (considered con-
stant) “11.00 mm”.
Example:
1) If the “53” is stamped on the final gear
case,
c = 42 + 0.53 = 42.53
2) If the “06” is stamped on the ring gear
bearing housing,
d = 2 + 0.06 = 2.06 mm
3) If the “–05” is stamped on the ring gear,
e = 33 - 0.05 = 32.95 mm
4) f = is 11.00.
5) Therefore, shim thickness “B” is,
“B” = 42.53 + 2.06 – (32.95 + 11.00)
= 44.59 – 43.95 = 0.64 mm
6) Round off hundredths digit and select
appropriate shim(s).
In the example above, the calculated num-
ber is 0.64. The chart instructs you to
round off the 4 to 5 at the hundredth place.
Thus, the shim thickness is 0.65 mm.
Shim sizes are supplied in the following
thickness.
