Repair - MS2 reverse gear and upper gear housing, sailboat drive
Final assembly
107. Put a needle roller bearing (1) on the vertical
shaft.
Then put on the measured spacer washer (2), the
three domed small washers (3), the large domed
washer (4) and the lock washer (5).
104. If the marking pattern resembles B, the shim
thickness in the input bearing housing should be re-
duced. If the gear flank clearance becomes too small,
the gear wheels must be disassembled.
Remove the shims from the gear wheels to the same
extent, and re-install the gear wheels.
Apply marking dye to the gears again, turn them round
and check the contact patches.
105. If the marking pattern is similar to C, move the
input gear housing and gear wheel in the opposite di-
rections to what was specified in item 104.
When the correct flank clearance and marking pattern
have been obtained, the input gear housing and upper
gear housing should be disassembled, and all marking
dye washed off.
NOTE! Keep the reverse gear upside down when the
lower gear wheel is washed clean, to prevent the dye
from finding its way into the bearing.
106. Measure distance (A) between the bearing and
gear wheel hub. This distance should be between 3.4
and 3.8 mm (0.13 and 0.15").
If the distance is 4.10 mm (0.161"), for example, a
spacer washer must be inserted.
If the distance exceeds 4.20 mm (0.165"), two spacer
washers must be inserted.
