Install Instructions

NOTICE:
Protect machined surfaces while you clean the parts. Failure to do so may result in
equipment damage.
6.2.1 Replacement guidelines
Impeller replacement
This table shows the criteria for replacing the impeller:
Impeller parts When to replace
Impeller vanes • When grooved deeper than 1/16 in. (1.6 mm), or
• When worn evenly more than 1/32 in. (0.8 mm)
Vane edges When you see cracks, pitting, or corrosion damage
Gaskets, O-rings, and seats replacement
• Replace all gaskets and O-rings at each overhaul and disassembly.
• Inspect the seats. They must be smooth and free of physical defects.
• Replace parts if the seats are defective.
6.3 Reassembly
6.3.1 Reinstall the seal
1. Clean the shaft sleeve and seal seat recess.
You can use crocus cloth in order to polish the sleeve. Do not scratch or gouge the
recess or sleeve.
2. Install the seat gasket, seat, and retainer (if used) into the seal recess in the faceplate or
coverplate.
3. Lubricate the inside diameter of the seal head with soapy water and then slide the
complete seal head over the shaft.
4. Slide the seal head assembly on until the carbon ring contacts the seat.
5. Use the flat face of a screwdriver and firmly press on the top of the edge of the
compression ring at several locations in order to make sure that the seal head sits flat
against the seat.
6.3.2 Reinstall the bearing assembly and impeller
WARNING:
Whenever the bearing assembly is removed from the pump, use a new gasket when you
reinstall. Failure to follow these instructions can result in serious personal injury or
property damage.
1. Wipe the bearing bores clean and remove any rust or scale deposits with a fine emery
cloth.
2. Insert the new wave spring into the rear bearing bore.
3. Lubricate the OD of the rear bearing with grease:
– On shaft assemblies that go into aluminum housings, lubricate the OD of the
bearing holder, not the faceplate.
– On shaft assemblies that go into cast iron housings, lubricate the OD of the front
bearing.
4. Insert the shaft assembly into the housing and then install and tighten the retaining
screws.
5. For cast iron bearing assemblies, install the coverplate on the housing.
6. If used, install the adapter ring and gasket on the new bearing assembly.
