#1 (29770) and nut #3 (22655).

2. Thread pipe plug #16 (21255) into housing

#14 (26587).

3. With the housing on the bench, suction down,

place the impeller and drive sleeve assembly

into the housing.

4. Assemble the adaptor #9 (29160) to the

housing with gasket #15 (31518) between

washers #17 (21266), and hex nuts

#25 (21241).

5. Install three gaskets #6 (29165), two carbon

isolators #10 (29158) and one O-ring #8

(29230) onto drive sleeve. The O-ring and one

gasket go between the two carbon isolators.

The second gasket goes between the carbon

isolators and the adaptor. The third gasket goes

between the carbon isolator and the seal

housing.

6. Assemble seal #2 (29773) onto the drive sleeve

with a liberal amount of grease to prevent the

seal from being damaged.

the lip seal.

8. Assemble the seal housing #12 (29772) to the

adaptor #9 (29160) with three 5/16-18

applied to the seal housing to hold it in

place, thread the three 5/16-18 screws in

and torque them to 25 inch-lbs. each.

Working around the bolt circle tighten the

screws in 25 inch-lbs. increments until each

screw is tightened to 150 inch-lbs.

towards the motor until it stops (contact with

the impeller and isolater). Tighten the drive

clamp screws to 120/140 inch-lbs. and install

piping.

Follow oil manufacturers guide for fill

and start-up. The seal cavity will vent
