Repair - MS2 reverse gear and upper gear housing, sailboat drive
77. Assume that the marking on the gear wheel =
65.00 mm. Only 00 is stamped on the gear wheel.
Put the outer bearing race on and measure the depth
of the gear wheel and the small roller bearing, as
shown in the illustration. For example, 37.10 mm.
The marking on the gear wheel is 65.00 mm and we
have measured the gear wheel + bearing to 37.10
mm. This gives us 65.00–37.10 = 27.90 mm.
Since D–E = 27.52 mm, this gives the shim thickness
27.90–27.52 = 0.38 mm.
78. Press the large ball bearing onto the slipping
clutch. Use tool no. 884732 and tool no. 884733 under
the small gear wheel .
Use the original shims when only new ball bearings
have been installed. In other cases, the shim thick-
ness must be calculated as in items 76–77.
79. Place the shims, as calculated, in the housing. In
this case, they are 0.40 mm.
80. Press the small bearing race into the housing. Use
tool no. 884732 .
