SHAFT SEAL
REPLACEMENT
A lip type shaft seal is used in the Series 45 open circuit variable pumps. This seal can be
replaced without major disassembly of the unit. Replacement of the shaft seal requires
removal of the pump from the machine.
CAUTION
Premature bearing failure
can result if the shaft seal
contacts the shaft bearing.
Press the seal into the
housing only far enough
to clear the retaining ring
groove.
Removal
1. Using the appropriate snap-ring
pliers, remove the retaining ring
(K010) from the housing.
2. Remove the shaft seal (K020) from
the bore in the pump housing and
discard. Avoid damaging the pump
housing or shaft.
Puncture the face of the seal with
a packing hook, or use a slide-hammer
type puller to remove the seal.
Installation
3. Inspect the pump housing and new
Shaft seal and retaining ring
seal for damage. Inspect the sealing area on the shaft for rust, wear, or contamination.
Polish the sealing area on the shaft if necessary.
4. Lubricate the lip of the new shaft seal with clean hydraulic fluid. Place a protective
sleeve over the shaft end to prevent damage to the seal during installation.
5. Keeping the seal perpindicular to the shaft, press the new seal into the housing just
far enough to clear the retaining ring groove.
Install seal with the cupped side
toward the shaft bearing. Do not damage the seal during installation.
6. Using the appropriate snap ring pliers, install the seal retaining ring.
7. Remove the installation sleeve.
