SHIMMING

Forward gear shim

NOTE:

Find forward gear shim thickness (T1) by

selecting shims until the specified measure-

ment (M) is obtained with the special tool.

1. Measure:

● Measurement (M)

NOTE:

Measure the length between the shimming

plate and the bearing outer race after turn-

ing the outer race 2 to 3 times.

2. Calculate:

● Forward gear shim thickness (T1)

NOTE:

● F is the deviation of the lower case dimen-

sion 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.

● If the F value is negative (–), then subtract

the F value from the measurement.

Example:

If M is “22.30 mm” and F mark is “+5”,

then T1 = 22.75 mm + (+5)/100 – 22.30

= 0.45 + 0.05 mm

= 0.50 mm

If M is “22.30 mm” and F mark is “–5”,

then T1 = 22.75 mm + (–5)/100 – 22.30

= 0.45 – 0.05 mm

= 0.40 mm
