carbon ring.
In
some cases it may be bonded to the
retainer.
Remove the seal assembly from the shaft
by
prying
behind the drive ring which is
that
portion
of
the seal
assembly farthest back on the shaft. When prying
the seal assembly from the shaft, do not scratch the
crankshaft
or
the sealing housing face on the
crankcase.
All parts should
be
cleaned prior to re-assembly.
INSTALLATION
Check the front face
of
the crankshaft front bearing
journal
in
the seal housing, to make certain
that
the
two seal drive pins are in place. These two drive pins
are located l
B0°
apart
on the front bearing journal
face.
Wash all portions
of
the seal assembly in clean
refrigerant oil.
Push the seal assembly, less the carbon ring,
if
it
is
free, over the end
of
the shaft, with the carbon ring
retainer facing out. Move the assembly along the
shaft a
few
times to ensure a good seal between the
neoprene ring and the shaft. Push the seal assembly
all the
way
on the shaft making sure the slots in the
seal drive ring engage the drive pins on the shaft
bearing journal face.
If
the carbon ring is separate, place it in the ring
retainer
so
that
the polished surface is facing out.
The carbon ring must engage the driving lugs and be
fully seated in the ring retainer.
Place a very light film
of
clean refrigerant oil on
the matching metal foccs where the seal plate gasket
is
to be placed. Place the seal plate gasket, dry, in
position on the seal housing face.

Position
Place the seal face plate in position with the polished
portion facing the carbon ring and insert the cap-
screws with the washers.
Turn
in the capscrews
evenly while rotating the shaft, making sure there
is
even clearance between the shaft
and
shaft hole in
the face plate.
If
clearance is not the same all
around the shaft, gently tap the seal face plate into
position until there is equal clearance. After equal
cleo.ro.nce
is obtained, tighten all the capscrews
by
tightening diagonally opposite capscrews evenly to
the required
90
lb. in. torque.
