Jackson Rack Conveyor Dishmachine - Manual (Page 4)

10. Note that the mechanical seal will consist of the following parts:
1. A rubber seal with a ceramic ring set inside it that will
seat in the center of the mounting plate.
2. A rubber seal with a stainless steel covering on the out-
side that seals the motor shaft and seats against the ceramic ring.
3. A spring.
4. A stainless steel spring cap to capture the top of the
spring and hold it in place.
11. Most of the mechanical seal should simply come off, leaving
the rubber seal with the ceramic ring inside the pump mounting
plate.
12. Using a screwdriver, pry out the remaining part of the mechan-
ical seal, taking care not to score or damage the motor shaft.
13. Once the hole is free of any parts of the mechanical seal, ver-
ify that the hole is clean and free of debris.
14.Gently press the new seal and ceramic over the shaft and slide
down into the mounting plate hole. NOTE: Do not touch the surface
of the seal with your bare fingers; place a rag or paper towle
between your fingers and the seal. Gently slide the shaft seal over
the shaft and push it down against the mounting plate seal. Place
the spring and cap over the shaft.
15. Place the woodruff key back into the groove of the motor shaft
and re-install the impeller, being careful to align the woodruff key
with the slot in the impeller. Replace the bolt and washer, then
tighten.
16. Install the motor by placing it on the studs and sliding it forward
until it is against the wash tank wall. Replace the nuts and wash-
ers and tighten.
17. Re-install the pump motor support bracket and tighten down
the nuts used to secure it to the tub.
18. Replace the band clamp on the motor and support bracket,
tighten until snug.
AFTER MAINTENANCE ACTIONS
Reconnect the incoming water (if disconnected) and turn
on. Then restore power to the unit. Run the unit for at least 10 min-
utes to ensure there are no leaks. If you hear any grinding sounds
while the motor is running, immediately shut off the unit and secure
power and water. There is a serious problem that must be
addressed. If any problems arise you can contact Jackson
Technical Service.
