Since final drive gear shims can
only
be
selected
in
0.10
mm
(0.003 in) increments,
round
off
the hundredths
digit
and select
the
appropriate shim(s).

In the example above, the calculated final
drive gear shim thickness is
0.51
mm
(0.02
in).
The chart instructs you to round
off
the 1 to
O.
Thus you should use a
0.50
mm
(0.02
in) final
drive gear shim.
• To
find
the ring gear shim thickness
"B",
use
the
following
formula.
Ring gear
shim
thickness:
B=© + @ -
(@

Where:
© = a numeral on the final gear case
(Le.45.55)
<C)
a numeral on the bearing housing (I.e.
1.35)
® a numeral (usually a decimalnumber)
on
the inside
of
the ring gear either added
to
or
subtracted from "35.40".
CD
= the ring gear bearing thickness (consid-
ered constant).
Ring gear bearing thickness
CD:

mm
(0.43 in)
Example:
If
the
final
gear case is marked
"55"
©
is
45.55
<C)
is 1.35
If
the
ring
gear
is
marked
11-05"
..........®
is
35.35
CD
is 11.00
"B"
= 45.55 + 1.35 - (35.35 + 11.00)
= 46.9 - (46.35)
=0.55
