Procedure

Equipment

Not Ready/

Available If:

•

Use the proper lubricant

to purge all four bearing

seals of each universal

joint. This flushes

abrasive contaminants

from each bearing and

assures all four bearings

are filled properly. Pop

the seals, these seals are

made to be popped.

•

If any seals fail to purge,

move propeller shaft from

side-to-side while

applying gun pressure.

This allows greater

clearance on thrust end of

bearing that is not

purging. If seals still do

not purge, rock vehicle by

releasing the parking

brake, start engine, put

transmission in D (drive)

or R (reverse), and allow

vehicle to roll. This

removes the windup in

the drive line and allows

for a greater clearance on

the thrust end of the

universal joint.

•

Because of the design of

the universal joint seal,

there will occasionally be

one or more bearing

seals of a joint that may

not purge. If this occurs,

notify field level

maintenance.
