Propeller Shaft Installation - PREVOST H3-41 Maintenance Manual

2. After all traces of grease and cutting
solvent have been removed from the yoke
shaft and spline sleeve, apply half of the
grease provided to the yoke shaft splines
and the other half to the spline sleeve, cover
the entire splined surface.

3. Measure and place a mark 2.25 inches
(55-60mm) from yoke shaft shoulder with a
marking stick, paint marker or other legible
marking device.

4. Position a clamp on each end of the new
boot. Slide the boot onto the grease-free
yoke shaft shoulder.
5. Collapse the boot and insert the yoke
shaft into the splined sleeve, making sure
phasing marks are in line. Position the end
of the boot at the 2.25 inches (55-60mm)
mark made on the yoke shaft shoulder and
tighten boot clamps to the specified torque.
Yoke shaft shoulder must be clean, dry and
grease free.
Failure to properly install and tighten boot
clamps could allow
contaminants and can cause driveline failure,
which can result in separation of the
driveline from the vehicle.
6.
Before the propeller shaft is completely
installed in the vehicle, slowly collapse and
extend the propeller shaft to make sure the
boot clamps are stationary. If the clamps are

PROPELLER SHAFT INSTALLATION

1. Before installing the propeller shaft,
inspect the yoke surface for burrs and
damage. Mating surfaces should be clear of
rust, contamination and grease.
2. With safety straps in place, align the
phasing marks between the yoke and
propeller shaft.

THE YOKE AND PROPELLER SHAFT
3. Align the bearing cups with the yoke
ears making sure that the cups are evenly
spaced between the tabs (ears) of the yoke.
A soft faced hammer can be used to fully
seat the bearing cups into the yoke.
FIGURE 26: YOKE TAB (EAR)
Note: Bearing cups must be fully seated
between the yoke tabs (ears). Failure to
seat the cups properly will result in a
premature failure.
4. Install bearing retainers and lock bolts.
5. It is important that the bearing retainer
bolts are torqued in the correct sequence.
