M4' M4
M4 = M4' – 10 mm
NOTE:
• Select the shim thickness (T2) by using the
specified measurement(s) and the calcula-
tion formula.
• Measure the height from the ball bearing at
4 points to find the height average.
4. Calculate the reverse gear shim thick-
ness.
Calculate formula:
Reverse gear shim thickness (T2) =
58.05 – (M3 – M4)
5. Select the reverse gear shim(s) (T2) as
follows.
Calculated number
0.00–0.10
0.11–0.20
0.21–0.30
0.31–0.32
Available shim thicknesses:
0.1, 0.2, and 0.3 mm

gear backlash
NOTE:
• Remove the water pump assembly before
measuring the backlash.
• Secure the drive shaft housing to the lower
case using 6 bolts (M8 × 25 mm).
1. Install the lower unit onto a repair stand.
2. Set the shift rod to the N position at the
