Oil Replacement

Motor Housing - Drain all oil (if not already done so) from motor housing and dispose of properly per Local and
Environmental Standards.
Set pump upright and refill with new cooling oil, see "Cooling Oil" chart. Fill to just above motor as an air space must
remain in the top of the motor housing to compensate for oil expansion. Apply pipe thread compound to threads of
pipe plug (40) then assemble to motor housing (31).
DO NOT overfill oil. Over filling of housing with oil can create excessive and dangerous hydraulic pressure which can
destroy the pump and create a hazard. Overfilling oil voids warranty.
WARNING! - Before any service work is done, disconnect and lock out electrical power to pump.
Disassembly
Cutter - Lay pump on its side, Use a flathead screwdriver to hold the shaft, then turn the radial cutter (20) counter-
clockwise to release the radial cutter (20).
CAUTION! - Cutter edges are very SHARP. Cutter must be removed before removing volute.
Volute – Remove cap screw (19) then remove volute (21) and volute washer (26) from pump.
Shredding Ring – Remove cap screw (24), then to replace or reverse the shredding ring (22) press out using an
arbor press.
Impeller - Remove impeller (25) by turning counter-clockwise while holding the motor shaft stationary with a
screwdriver.
NOTE: Seal spring is relaxed with impeller removed, some oil may seep from seal cavity. Do Not store pump without
impeller in place.
Seal Plate –Remove oil plug (27), then drain all oil from
seal plate (17). Remove cap screws (18) from seal plate
(17). Remove seal plate (17) and O-ring (15) from bearing
bracket (16). With flat screwdriver, press out seal (28)
stationary member. Inspect O-ring (15) for cuts or
abrasions.
Seal - Handle seal parts with care. Remove seal (28)
spring and rotating member from shaft. Examine all seal
parts. Inspect contact faces for signs of uneven wear
tracks on stationary, chips and scratches on either seal
face. DO NOT interchange seal components, replace the
entire shaft seal (28). (See Figure 2)
IMPORTANT! - All parts must be clean before reassembly. Handle seal parts with extreme care. DO NOT damage
lapped surfaces.
Power Cable-Remove pipe plug (40) and drain oil if not already done so. Position pump upright using blocks or PVC
pipe to avoid resting pump on the shaft. Remove cap screws (2) and power core plate (3) from power cord (1) and
remove power cord (1) by pulling straight up.
