Quincy Compressor-QSI

Preparation for New Seal Installation

• Inspect the compressor shaft for burrs or deep

scratches at the wear sleeve area. Using a 100-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™ 290 to the 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 ham-

mer.

• Preheat the wear sleeve (in a small oven) to 350°F.

Do not preheat in warm oil.

• Apply a thin film of Loctite™ to the 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.

Seal Installation

•

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 in-

stalled over the end of the rotor shaft and up against

the adapter bore.

•

Using care not to damage the o-ring, 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.

•

Reinstall drive motor, and coupling.

•

Reinstall the coupling guards before starting the

compressor.

Air and Fluid Tubing

Flareless tubing is used in the air piping to eliminate pipe

joints and provide a cleaner appearance. Replacement

tubing and fittings are available; however, special instal

lation procedures must be followed. Your authorized

distributor has the necessary instructions and experience

to perform these repairs.

WARNING!

Failure to install flareless tubing or fittings cor

rectly may result in the tubing coming apart

under pressure. Serious injury and property

damage may result.
