See Fig. 72-43.
There are two important toothed shaft connections in the gearbox.
– crankshaft to drive gear
– propeller shaft to clutch hub of the overload clutch
Carry out a visual inspection of all toothed shaft profiles for damage
and wear.
To check the toothed shaft profiles, the tooth width at the head of
the respective inner and outer gear-tooth system must be mea-
sured. The lowest value is decisive in each case.
