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.

If the seal plate was removed, install the seal plate

To prevent damaging the shaft sleeve O-ring (24)
on the shaft threads, stretch the O-ring over a piece
of tubing 1-9/16-inch I.D. x 1-13/16-inch O.D. x 2-in-

over the shaft threads, then slide the O-ring off the
tube and onto the shaft. Remove the tube, and
