Propeller Shaft Maintenance Directive - PREVOST H3-41 Maintenance Manual

SECTION 09: PROPELLER SHAFT
Furthermore, a slip joint on the propeller shaft
compensates for variations in distance between the
transmission and the differential, or between the
output retarder (optional
transmission) and differential.
The rise and fall of the drive axle bring about
these variations as the vehicle passes over
uneven surfaces. The slip joint also eases
removal of the transmission or the drive axle.

WARNING
DO NOT reuse bearing retainer bolts.

DIRECTIVE
Before removing the driveshaft from
•
vehicle, inspect all components (universal
joints, slip joints,
deterioration (rust or corrosion) or excessive
play. If all components pass inspection,
grease universal joints until they are properly
lubricated (fresh grease showing at all u-joint
end caps). If any component does not
accept grease, it must be replaced.
Replace splined slip joint if seal is
•
damaged or if welch plug (cap) is missing
(when applicable).
• Unless the slip section (joint) is being

an assembly. The driveshaft must be
completely disconnected from the differential
and transmission yokes only; the slip
section must not be disconnected unless it is
being replaced.
