Repair - MS2 reverse gear and upper gear housing, sailboat drive
11. Put the gear shift mechanism in a position be-
tween forwards and neutral. The pin should rest in one
of the “notches”.
12. NOTE ! During assembly, the dog must be aligned
as shown in the illustration. The gear shift mechanism
will not work if the dog is turned the other way round.
13. Undo screw (1) about 2 turns and install the gear
shift mechanism in the housing. Check the position of
the dog. The screw must be displaced backwards, i.e.
to the right in the illustration.
Disassemble the screw, remove the shim and re-tight-
en the screw. It will now be impossible to turn the out-
put shaft round.
Install one shim at a time until the shaft can be turned
without resistance.
After adjustment, apply sealant with Volvo Penta part
no. 1141570-0 to the shims and screw, then tighten
the screw.
10. Put a new O-ring (1) on the gear shift mechanism.
Install the spring (2) and dog (2).
