MAINTENANCE & REPAIR PAGE E - 10
When installing the shaft and bearings into
the bearing bore, push against the outer
race. Never hit the balls or ball cage.
Press the outboard oil seal (18) into the bearing
cap (12) with the lip positioned as shown in Figure
2. Replace the bearing cap gasket (11), and secure
the bearing cap with the hardware (13 and 14). Be
careful not to damage the oil seal lip on the shaft
keyway.
Install the bearing housing O‐ring (30).
Lubricate the bearing housing as indicated in LU­
BRICATION.
Seal Installation
(Figures 2, 5, 6 and 7)
Most cleaning solvents are toxic and
flammable. Use them only in a well ven­
tilated area free from excessive heat,
sparks, and flame. Read and follow all
precautions printed on solvent contain­
ers.
Clean the seal cavity and shaft with a cloth soaked
in fresh cleaning solvent. Inspect the stationary
seat bore in the seal plate for dirt, nicks and burrs,
and remove any that exist. The stationary seat bore
must be completely clean before installing the
seal.
A new seal assembly should be installed
any time the old seal is removed from the
pump. Wear patterns on the finished faces
cannot be realigned during reassembly.
Reusing an old seal could result in prema­
ture failure.
To ease installation of the seal, lubricate the shaft
sleeve O‐ring and the external stationary seat O‐
ring with a very small amount of light lubricating oil.
See Figure 5 for seal part identification.
