Open-Drive Compressors

Step 1

— Lubricate the shaft and the neoprene

bellows where it comes in contact with the shaft.
Slide the seal assembly, as it is shipped from the

factory, onto the shaft until the neoprene just
starts to grasp the shaft.

Step

3 — Using the seal cover plate, push the

seal assembly into its proper location on theshaft.

DO NOT use cover plate bolts to push seal into
position. The spring guide should be tight against

the shaft shoulder as shown by the pencil. Re­

move the cover plate, being careful not to damage

the carbon washer. GRASP THE SEAL NOSE
ASSEMBLY AND TURN IT UNTIL THE LUGS
ON THE DRIVING BAND DROP BACK INTO
THE SLOTS IN THE RETAINER SHELL.

Step 2

— Holding the sleeve and spring assem­

bly, pull forward on the seal nose assembly at the

same time, turning it so that the lugs on the driv-.

ing band are out of the slots in the retainer shell
and rest on the surface of the retainer shell as
shown by the pencil.

Step 4

— Lubricate the carbon seal washer and

seal seat. Reinstall the seal cover plate, drawing
the bolts down evenly to prevent damage to the
carbon seal nose. This view shows the lugs of the
driving band properly positioned in the center of
the slots in the seal retainer shell. This is the

correct position during operation. This prevents
the seal from being used as a thrust washer under
all operating conditions.

NOTE The seal may leak slightly immediately after installation, but a short period of operation will correct the condition.
