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 (24) into the bearing
cap (26) with the lip positioned as shown in Figure
2. Replace the bearing cap gasket (13), and secure
the bearing cap with the hardware (14 and 15). Be
careful
not to damage the oil seal lip on the shaft
keyway.

Lubricate the bearing housing as indicated in LU­
BRICATION
.

Seal Installation

(Figures 2 and 4)

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.

Handle the seal parts with extreme care to prevent
damage. Be careful not to contaminate precision
finished faces; even fingerprints on the faces can
shorten seal life. If necessary, clean the faces with a
non‐oil based solvent and a clean, lint‐free tissue.
Wipe lightly in a concentric pattern to avoid
scratching the faces.

If a replacement seal is being used, remove it from
the container and inspect the precision finished
faces to ensure that they are free of any foreign
matter.

To ease installation of the seal, lubricate the O‐
rings and seal sleeve with water or a very small
amount of oil, and apply a drop of light lubricating
oil on the finished faces. Assemble the seal as fol­
lows (see Figure 4).
