SHIM SELECTION
(EXCEPT FOR USA AND CANADA)
NOTE:
●
Use a minimum number of shims to
obtain the thickness equal or nearly equal
to the calculation.
●
Install the shims with the thicker one on
the outer side.
Forward gear shim
1. Find forward gear shim thickness ( T1 )
by selecting shims until the specified
measurement (
M ) with the special tool
is obtained.
2. Using a digital caliper at the specified
measurement ( M ) established above,
measure the bearing height.
3. F is the deviation of the lower case
dimension from standard. It is stamped
on the trim tab mounting surface of the
lower case in 0.01 mm units. If the
F
mark is missing or unreadable, assume
an
F mark of “0” and check the backlash
when the unit is assembled.
Example:
If M is “23.90 mm” F is “+5”, then
T1 = 24.50 + 5/100 – 23.90 = 0.65
Shim thickness (T1)=
50 hp:
22.70 mm + F/100 mm – M
60 ~ 90 hp:
24.50 mm + F/100 mm – M
