Since final drive gear shims can only be se-
lected in 0.10 mm increments, round off the
hundredths digit and select the appropriate
shim(s).
Hundredths
Rounded value
0, 1, 2, 3, 4 0
5, 6, 7, 8, 9 10
In the example above, the calculated final drive
gear shim thickness is 0.51 mm. The chart
instructs you to round off the 1 to 0. Thus you
should use a 0.50 mm final drive gear shim.
D To find the ring gear shim thickness “B”, use
the following formula.
Ring gear shim thickness:
B = + – ( + )
Where:
c
= a numeral on the final gear case (i.e.45.55)
d
= a numeral on the bearing housing (i.e.1.35)
e
= a numeral (usually a decimalnumber) on
the inside of the ring gear either added to or sub-
tracted from “35.40”.
f
= the ring gear bearing thickness (consid-
ered constant).
Ring gear bearing thickness
f
:
11 mm
Example:
If the final gear case is marked
“55”
c
is 45.55. . . . .
d
is 1.35
If the ring gear is marked “–05”
e
. . . . . . .
is 35.35
f
is 11.00
“B” = 45.55 + 1.35 – (35.35 + 11.00)
= 46.9 – (46.35)
= 0.55
