Mark Propeller Shaft; Grease Zerks; Other Inspections; Removal - PREVOST H3-41 Maintenance Manual

• Visually inspect
retainers, loose bearing retainer bolts, loose
companion flange, bolts and nuts, loose or
missing spring tabs or spring tab bolts, damaged
tangs on end fittings, damaged or missing
rotating bearing cups. If any of these situations
are evident, replacement of the component is
necessary.
• Check all input and output end fittings for
looseness. Take hold of the end fitting with both
hands. Try to move it vertically and horizontally to
feel any looseness.
FIGURE 6: CHECK FOR LOOSENESS
There should be less than .006" movement
•
in the u-joint relative to the end yoke. If
looseness is greater than .006", the u-joint
should be replaced.
Check for the presence of all grease zerk
•
fittings. Damaged zerks should be replaced.
Loose zerks should be tightened.
4.3 MARK PROPELLER SHAFT (PHASING
MARKS)

PROPELLER SHAFT REMOVAL

1. Mark propeller shaft (phasing marks). It
is imperative to mark all the mating
components of
illustrated below. Mark the propeller shaft
with a marking stick, paint marker or other
legible marking device. In addition, be sure
to mark all bearing positions, spline positions
and shaft locations. This assures proper
reassembly of the propeller shaft into the
vehicle, in its original position.
