Reducer gear to pump drive shaft repair is limited to replacement of universal joints.

assembly including the universal joints.

Mark slip joint (1) position before separating to
ensure alinement of components during
assembly.

Unscrew dust cap (3) from slip joint (1) and
separate slip joint (1) from tight end (2).
(3)
Remove the cork washer (5), steel washer (4),
and dust cap (3) from the tight end (2).
(4)
Wipe excess grease from tight end (2), and
slip joint (1), and inspect splines for damage
such as wear, pitting, rolling, peening and
fatigue cracks.

Evidence of damage of any kind is cause for
rejection. Replace complete drive shaft
assembly. If no damage is found, continue
with step 6.

Remove grease fittings (6) from cross (7).

removal the following procedure will be carried out twice.
