22. Reinstall the shaft seal
following the procedure for
your type of seal.
a. Lubricate O-ring seal of
rotating seal. Then install
rotating seal with seal puller.
Ensure rotating seal O-ring is
placed inside the rotating seal
before assembly onto the
output drive shaft.
b. Lubricate O-ring seal of
stationary seal subassembly.
Then install stationary seal
subassembly.
c. Using a No. 5 or No. 7
retaining ring pliers, install
retaining ring (beveled side
of ring out).
For best sealing results,
clean the metal-to-metal
seal surfaces. The cleaner
must evaporate and not
leave any residue, and
must be compatible
with Viton.
Do not touch these
surfaces. Coat with
clean, filtered oil
before reassembly.
Note: There are two types
of shaft seals.
Depending on the date
of manufacture, either
type of seal may have
been used. A unit
MUST be serviced with
the same type of seal
as was originally
installed. The seals are
not interchangeable.
