CLEANING AND INSPECTION
1. Clean metal parts in solvent and blow dry with
compressed air.
IMPORTANT: Do not spin bearings at high speed
when drying with compressed air, as bearings
may be scored.
2. After cleaning, apply a coat of light engine oil to
shaft and bearings to prevent rust.
3. Clean all gasket material and sealer from sealing
surfaces.
4. Inspect bearing housing. Examine surfaces
(where bearings contact housing) for evidence of
bearing outer races turning in housing.
5. Inspect seals in bearing housing.
6. Inspect pump shaft bearings.
7. Inspect pump shaft for grooves in surface where
seals contact shaft. Also inspect surface where
bearings contact shaft for evidence of inner races
turning on shaft.
8. Inspect pump body.
9. Inspect inner and outer wear plate.
10. Inspect pump impeller for wear on sides and tips
of blades. Also inspect blades for cracks in area
where blades flex. Replace impeller if blades
have taken a set (remain in curved position).
11. Inspect pump pulley.
12. Check drive belt for excessive wear.
