Propeller Shaft Alignment

Description

The front and rear propeller shafts have non-constant velocity "Hooks" type universal joints, with needle belt bearings. The bearing cups are pre-packed with lubricant on assembly and a grease nipple is installed for servicing as specified, in maintenance section.

Both shafts have Rilsan coated sliding splines to accommodate the variation in distance between the axles and transmission. The splines are pre-packed with lubricant and sealed.

Drive Shaft, Front:

Front Shaft

The front shaft is a solid bar, which is shorter than the rear, with the joints "phased" et each end, A and B mis-aligned. The phasing is necessary on the front shaft only to allow for greater variation in angular changes.

Drive (Propeller) Shaft:

Rear Shaft

The rear shaft is a tube installed with a conventional joint at gearbox end and the sliding joint sealed with a rubber boot.
