Shift rod push arm: 90890-06052
Available shim thickness:
0.10, 0.12, 0.15, 0.18, 0.30, 0.40, 0.50
Calculated numeral

3,4,5 2
6,7,8 5
9,10 8
Example:
If "T2" is 1.16mm, then the reverse gear
shim is 1.15 mm.
If "T2" is 1.20mm, then the reverse gear
shims is 1.18 mm.
2. Calculate the lower case standard(R/100).

NOTE:
• "R" A stamped on the trim tab mounting face
refers to the deviation of the lower case di-
mension from the standard. The numeral is
in 1/100mm.
• If the numeral is unknown, assume that "R"
is zero, and check the backlash when the unit
is assembled. Readjustment shall be made
if the backlash is out of specification.
3. Calculate the reverse gear shim thickness.
Calculation formula:
Reverse gear shim thickness
(T2) = M2 - 29.00 - R/100
Example:
If "M2"= 30.50, and "R"= –5, then :
T2 = 30.50 – 29.00 – (–5/100)
= 30.50 – 29.00 + 0.05
= 1.45
4. Select the reverse gear shim(s) as follows.

NOTE:
• Measure the backlash before installing the
water pump.
• Set the gear shift in neutral position for the
measurement.
• Measure the backlash for both forward and
reverse gears.
Measuring the forward and reverse
gear backlash
1. Set the gear shift in neutral.

2. Secure the propeller shaft by pressing it by
the special tool.
