SECTION 5: SERVICE PROCEDURES
DRIVE MOTOR/GEAR REDUCER REPLACEMENT (CONTINUED)
AJ-54C Series Technical Manual 7610-002-30-91
Issued: 03-22-2006 Revised: N/A
Note: Because of the way the covers for the drive assembly
are designed, it is imperative that you position the motor on
the gear reducer so that the conduit fitting is facing towards
the front of the dishmachine. If it is facing away from the
machine, the covers may not go back on.
Removing the drive hub.
19. Reattach the bottom and top drive assembly covers.
20. Proceed to the sections entitled "AFTER MAINTENANCE
ACTIONS".
21. (Continuing from step 7) To remove the gear reducer, first
take the 3/4" combination wrench and remove the drive hub
bolt.
22. Once the drive hub bolt & bearing are removed, loosen the
set screw on the drive hub. There is no need to remove it.
23. Remove the gear drive by using the 9/16" socket and
ratchet, as well as the combination wrench as required, to
remove the nuts holding it to the mounting plate.
24. Gently remove the gear reducer, careful not to drop it.
25. Set the gear reducer on a flat surface. The drive hub
needs tobe removed. You have already loosened the set
screw, but it may take some more effort to remove it. You may
have pry it off, or give it some taps with a mallet to coax it off
of the shaft. The liberal use of spray lubricants will also help.
26. Once the drive hub is removed, place it on the shaft of the
new gear reducer. Ensure the key is in the keyway. Once it is
on and flush with the end of the shaft, tighten down on the set
screw with the 1/8" allen wrench.
