6. Drain oil from seal cavity by removing drain screw (Ref. No.
23) and seal (Ref. no. 22) from seal plate (Ref. No. 21). Then
tip components upright overtop of a catch pan until oil is
drained.
7. Remove three fasteners (Ref. No. 25) and pry out seal plate
with screwdriver. Slinger washer (Ref. No. 24) will come free
at this time.
8. Use a press or gear puller to remove shaft and bearings from
lower end bell. Shaft seal head will now be free.
IMPORTANT: Shaft seal head (with spring) has unique ends, and two
seal seats are different from one another also. Be sure to note size and
color of each before disassembly so that new parts are installed in
proper orientation.
9. Remove upper seal seat (Ref. No. 17) from lower end bell by
using a screwdriver or dowel to press on seal from rear. Do
the same for lower seal seat (Ref. No. 19) in seal plate.

11. Carefully wipe polished surface of new seal seats with a clean
cloth.
12. Wet outside of rubber portion of seal seats with a light coating
of soapy water.
13. Press each new seal seat squarely into cavity in both seal
plate and lower end bell. If seal seat does not press squarely
into cavity, it can be adjusted into place by pushing on it
carefully with a piece of pipe or dowel. Always use a piece of
cardboard between pipe and seal seat to avoid scratching
seal seat. (This is a lapped surface and must be handled very
carefully.)
14. After each seal seat is in place, insure that it is clean and has
not been marred.
15. Using a clean cloth, wipe shaft and make certain that it is
perfectly clean.
16. Carefully guide motor shaft through seal seat and use a press
to seat bearing back into lower end bell.
17. Apply a light coating of soapy water to inside rubber portion of
seal head and slide onto shaft (be sure to start correct end
first).

guide shaft and avoid damage to seal seat. Secure with
fasteners.
19. Press slinger washer back in place.
20. Refill cavity with oil through fill hole and reassemble in
reverse order.
