Preparation for New Seal Installation
• Inspect the compressor shaft for burrs
or deep scratches at the wear sleeve
area. Using a 00 grit emery cloth,
lightly sand horizontally any rust or
Loctite on the shaft. Using a fine file
™
or emery cloth, deburr the key area of
the rotor shaft. Cover the keyway with
masking tape to prevent damage to the
new seal during installation.
• Clean the seal adapter with fast drying
solvent. Assure that the scavenge drain
in the seal adapter is clean and open.
Place the outer face of the seal adapter
on a flat, hard surface.
• Remove the new triple lip seal from the
package and inspect for damage or
imperfections on the seal lips.
• Apply a thin coat of Loctite
outer steel case of the seal and position
the seal in the seal adapter bore.
• Insert the proper seal driver over the
seal. Insert the proper wear sleeve
driver in the seal driver and tap the new
seal into the bore with a medium sized
hammer.
• Preheat the wear sleeve (in a small
oven) to 350°F. Do not preheat in
warm oil.
• Apply a thin film of Loctite
inner diameter of the wear sleeve and
immediately install on the compressor
shaft using the proper wear sleeve
driver. Drive the wear sleeve on the
shaft until the driver bottoms on the
shaft shoulder.

Apply a thin coat of compressor fluid to
the outer face of the wear sleeve and
seal lip.

Slide the proper seal installation sleeve
against the wear sleeve with the taper
toward the end of the rotor shaft.
•
Install a new o-ring on the seal adapter
and lubricate with compressor fluid.
•
Install a new o-ring around the
scavenge port (use petroleum jelly to
hold the o-ring on the seal adapter face
during installation).
•
Carefully slide the seal adapter with the
new seal installed over the end of the
rotor shaft and up against the adapter
bore.
•
Using care not to damage the o-ring,
290 to the
™
evenly draw the adapter into the bore,
install the four retaining bolts and
tighten to the specified torque.
•
Remove the installation sleeve.
•
Apply a thin film of compressor fluid to
the o-ring and seal lip of the outer fluid
slinger.
•
Install the outer slinger over the end
of the rotor shaft and push into the
scavenge bore using both thumbs.
