ASSEMBLY

1. Install bracket bushing. If bracket bushing has a

lubrication groove, install bushing with groove at 6:00

o’clock position in bracket. If carbon graphite,

Refer to

Installation of Carbon graphite Bushings, page 10.

8.

Loosen four setscrews over the inner and outer end caps.

Remove both end caps with lip seals, spacer collars and

ball bearing.

Refer to figure 4.

The inner cap can be removed through side opening of

the bracket.

9. Remove packing and packing retainer washer.

10.

Clean all parts thoroughly and examine for wear and

damage. Check lip seals, ball bearing, bushings and idler

pin and replace if necessary. Check all other parts for

nicks, burrs, excessive wear and replace if necessary.

Wash bearings in clean solvent. Blow out bearings with

compressed air. Do not allow bearings to spin; turn them

slowly by hand. Spinning bearings will damage race

and balls. Make sure bearings are clean, then lubricate

with non-detergent SAE 30 weight oil and check for

roughness. Roughness can be determined by turning

outer race by hand.
If bearings have roughness, bearings will need to be

replaced.

11.

Casing can be checked for wear or damage while

mounted on bracket.

ring.

4. Install packing gland, capscrews and nuts. Back rotor

and shaft out of casing just far enough to insert packing

gland through side opening of bracket over end of

shaft. Make sure gland is installed square and nuts are

tightened evenly. Tighten nuts wrench tight then back off

until gland is slightly loose

.

5.

Coat idler pin with non-detergent SAE 30 weight oil and

place idler and bushing on idler pin in head. If replacing

with carbon graphite bushing,

Refer to Installation of

Carbon graphite Bushings, page 10.

6. Using a .015 inch head gasket, install head and idler

assembly on pump. Pump head and casing were marked

before disassembly to insure proper reassembly. If not, be

sure idler pin, which is offset in pump head, is positioned

toward and equal distance between port connections to

allow for proper flow of liquid through pump.
