C. CLEANING
1. To clean pump impeller (3), loosen the two Victaulic pipe clamps and remove suction pipe
assembly. The eye of the pump impeller can then be seen through the pump suction cover
(1) and is readily accessible for cleaning.
2. To further access pump impeller, remove eight bolts (5B) that hold pump suction cover (1)
in place. Remove pump suction cover, being careful not to damage O-ring (2).
3. To remove pump impeller, take the pump impeller wrench, which is stored in the tool box,
and position it so that the hole is aligned with any of the eight tapped holes in the front of
the pump casing (4). The 90-degree leg of the pump impeller wrench should face inward,
toward the pump impeller and be positioned between any two of the pump impeller fins.
Bolt the wrench securely in place with one of the pump suction cover bolts (5B). Using a
pipe wrench on the pump shaft (9), unscrew the pump impeller, turning the pump shaft in
a clockwise direction. Be careful not to unscrew the pump impeller too far before removing
the impeller wrench

D. INSTALLING NEW SEAL ASSEMBLY
NOTICE
Do NOT unwrap new seal assembly until you are ready to install. All parts of assembly are
packed in sequence of installation.
1. To replace seal assembly (5), perform the steps in CLEANING, and remove pump casing
(4) by removing four bolts (7B) that hold casing and casing bearing (7) to pump frame (15).
2. After cleaning all parts, including pump shaft, begin reassembly of pump. Install radial lip
seal (6) with the cavity portion of seal facing inward. Rebolt casing and casing bearing (7)
onto clutch housing using four bolts (7B). Using a light oil lubricant (such as 3-in-1 oil),
install the ceramic seat with its neoprene holder into the seal recess, making sure it is
square with the shaft. Lubricate the inside of the bellows assembly with a light oil lubricant
and check to make sure the steel ring is stuck (glued) to the end of the assembly. Slide the
bellows assembly onto the shaft and push until the steel ring is against the ceramic seat.
3. Install seal spring on hub of pump impeller. After coating the threads on the pump shaft with
an antiseize compound, install pump impeller, seating it securely.
