REAR CONSTANT VELOCITY JOINT/FINAL DRIVE GEAR
AND DRIVE SHAFT
h =bearing thickness (considered constant)
Bearing thickness h:
14.00 mm
Example:
1) If "98" is stamped on the final drive gear
case,
e = 50 + 0.98 = 50.98
2) If "55" is stamped on the ring gear bear-
ing housing,
f = 1 + 0.55
= 1.55
3) If "–05" is stamped on the ring gear,
g = 35 – 0.05
= 34.95
4) h = 14.00
5) Therefore, shim thickness "B" is 0.48.
"B"= 50.98 – 1.55 – (34.95 + 14.00)
= 49.43 – 48.95
= 0.48
6) Round off the hundredth digit and select
the appropriate shim(s).
In the example above, the calculated
number is 0.48. The chart instructs you
to round off 8 to 10 at the hundredth
place.
Thus, the shim thickness is 0.50 mm.
Hundredths
0, 1, 2
3, 4, 5, 6, 7

nesses.
