5. Remove the carbon seal ring
and seal housing assembly from the
crankshaft. A disassembled view of
the crankshaft seal assembly is in-
cluded in Fig. 24.
6. Clean all old gasket material
from the seal plate and the com-
pressor. Make certain that the shaft,
the seal plate and the compressor
gasket surfaces are completely clean.
7. Check the face of the crank-
shaft front bearing journal in the
seal housing to make certain that
there are no nicks or
burrs.
Check the
crankshaft surface to be sure it is not
damaged. Check all parts of the seal
assembly to be sure that they are not
damaged.
8. Inspect the compressor internal
components for damage.
Installation
1.
Wash the new seal assembly
components in clean refrigeration
oil.
2. Position the seal over the end
of the shaft with the carbon ring
retainer facing out. Move the seal in
and out on the shaft a few times to
insure a good seal between the seal
and the
shaft.
3. Push the seal all-the-way on
the
shaft.
Be sure that the seal drive
ring slots engage the drive pins on the
shaft bearing journal face.
4. Place the carbon ring (Fig. 24)
over the shaft and in the seal ring
retainer. The polished surface of the
carbon ring must face out and the
lugs must engage the ring retainer and
be fully seated.
5. Apply a light film of clean re-
frigeration oil on the matching faces
of the crankcase and seal cover plate.
Then, place the gasket in position
on the crankcase face.
6. Place the seal cover plate
in
position (Fig. 24), with the polished
side facing the carbon ring.
Then,
install the cap screws. Tighten the
cap screws evenly while turning
the
crankshaft. Be sure that
the·
clearance
between the crankshaft and the hole
in the seal cover plate is even all
around the shaft. ·If the clearance
is
not equal all around the shaft, gently
tap the seal face into position until
the clearance is equal. Then, tighten
diagonally opposite cover plate
cap
screws evenly to 7-13 ft-lbs.
7. Make certain that there are no
burrs or dirt on the compressor
shaft.
Install the key and magnetic clutch
on the shaft.
8. Install the belt and adjust the
tension to specification.
9. Check the compressor oil level
(Section
3).
