MOTOR INSPECTION AND

CLEANING

Inspect and clean all parts as follows:

CLEANING

Clean all parts with a degreasing solvent. Blow dry with compressed air and wipe clean. Use only lint-free cloths.

GEAR HOUSING

The chamber bores and bottoms around the shaft bushings should be polished and not rough or grooved. If the bush- ing bores are yellow-bronze, replace them and investigate the cause of wear.

The fl at surfaces around the chamber and bolt holes should be fl at and free of nicks or burrs that could cause misalign- ment or leaks.

BUSHINGS

The inside of the bushings should be gray with

some bronze showing through. If signifi cant yellow-bronze shows, replace the bushings. Inspect motor shaft for cor- responding wear and replace as required.

GEARS

The drive and idler gears should have straight tips without nicks, square tooth ends and a smooth even polish on the teeth and end faces. Check for cracks between the drive gear keyway and gear tooth root. Replace the gear if cracks are present.

VALVE HANDLE MOTOR SURFACE

The surface near the gears should show two interconnect- ing polished circles without a step. The bottom of the o-ring
