New Holland CX720 Repair Manual page 2512

Pump Shaft - Remove (C.20.F.20.18 - F.10.A.10)
NOTE: The same procedures for the replacement of the shaft seal apply to the pump and the motor (pump shown).
1. Remove the pump/motor in accordance with their ap-
propriate sections.
Remove cap screws (1) holding the seal cover and
the seal retainer (2).
2. After removal of the cap screws, the seal cover may
move out of its bore by approximately 6 mm (0.25
in). An outward spring force on the shaft will tend
to overcome the friction from the O ring on the seal
cover outside diameter. If the seal cover does not
move from its bore upon removal of the cap screws,
then gently pry it from the bore as shown.
3. Place the seal cover and seal in an arbor press and
remove the old seal.
Inspect the seal cover, the new seal, and the O ring
for any damage or nicks.
NOTE: After the seal cover is removed, the shaft is free and
can be removed or may fall out of the unit. Do not remove
shaft.
