23) Removal of Drive Shaft
1.
Remove the bevel gear B nut 1 , and remove the bevel
gear B 2 and drive shaft.
• Degrease the bevel gear B nut completely so
that the nut wrench does not slip on the nut.
• Loosen the nut by rotating the bevel gear B nut
socket 3 in a counterclockwise direction with
a wrench. Cover the bevel gear B nut wrench
4 with a rag or the like to prevent it from hitting
the gear case directly.
• This work can be made easier when the
opening of the gear case on the propeller shaft
side is faced upward and fixed horizontally with
a vice or other holder.
