Circulation Pump / Motor Assembly

Fig. 16-7

Disconnect the four wire leads, then grasp the Circulation Motor and turn clockwise a quarter turn until the Motor stops, Fig. 16-2. Now, remove the Motor / Rear Pump Assembly from the Front Pump Housing, Fig. 16-3.

Note: The Front Pump Housing remains in place when the Motor is removed, Fig.16-3, item 1.

With the Motor / Rear Pump Assembly removed from the unit, separate the Motor from the Rear Pump Assembly. To do so, first remove the Impeller by placing a block in the rear of the Motor and then turning the Impeller counter-clockwise, then Fig 16-4.

The Rear Pump Assembly consists of four components, Fig. 16-5:

1.	Rear Pump Housing.	3.	Impeller.
2.	Main Pump Seal.	4.	Impeller Seal.

Each component can be replaced as an individual item.

TO INSTALL:

First, locate the Key Square on the Front Pump Housing, Fig. 16-6. Next, locate the Key Square Cut Out on the Rear Pump Housing, Fig. 16-3, item 2.

When replacing the Pump / Motor make sure to line up the Key Square with the Key Square Cut Out. Then bring the two pump halves together in the position shown in Fig. 16-2, and turn the Motor clockwise until it stops, see Fig. 16-7.

Service note: The Impeller Seal Spring is compressed when the two halves of the Pump Assembly are brought together. This will take a little force, so make sure to have a good grip on the Sump as you compress the spring.

Now, reattach the wiring leads, test and check for leaks.
