SERVICE:
Tools needed
Phillips screwdrivers (#1 and #2), locking pliers, 10 mm and 17
mm wrench, ball bearing puller.
A. Disassembly of pump top.
(Check wires, rotor, stator, ball bearings and oil). Remove (pos 39)
handle screws (pos 4). Remove handle. Remove (pos 37) top
cover screws (pos 2) and open top cover. Disconnect wires,
remove motor housing cover (pos 3). Inspect the quality of the oil.
If milky or whitish in color, check seals and replace (both seals and
oil) if necessary. To remove rotor, ball bearings and seals, follow
steps described in B. Disassemble pump bottom before
proceeding. Once impeller is off, pull out rotor. Inspect bearings,
replace if necessary. Press out lip seals. Inspect and replace as
necessary.
B. Disassembly of pump bottom
(strainer, suction cover, impeller) Remove strainer screws (pos
36), remove strainer (pos 6) and suction cover (pos 7). Hold
impeller with vise grip and remove impeller screw (pos 40).
Remove impeller (pos 5). Impeller vanes should have sharp
edges to maximize performance. Replace impeller if vanes are
rounded or dull.
Inspection of pump bottom parts.
Look at lower lip seal parts (pos 27) for visible wear. If damaged
or worn replace both lip seals. To replace lip seals, disassemble
top portion of pump first and remove the oil (see A., disassembly
of pump top).
Note: Bot seal openings s ould face down.
C. Important notes on re-assembly of pump
All O-rings should be lubricated with a silicone based grease, or
lubricated with same oil as in motor, before assembly. Replace
ball bearings to shaft. To re-install inner cover, lubricate bearing
holder. Use a plastic or rubber mallet to lightly tap until cover is in
place. It is important that the bearing is in the absolute center of
the bearing holder when closing the top cover. If not centered, the
shaft will not turn freely.
