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
