1. Check all mating surfaces. Replace any parts with
scratches or burrs that could cause leakage or dam-
age. Clean all metal parts in clean solvent. Blow dry
with air.
2. Check around the key slot and chamfered area of the
shaft for burrs, nicks or sharp edges that could dam-
age seals during reassembly. Remove nicks or burrs
with a hard smooth stone (such as an Arkansas stone).
Do not file or grind motor parts.
NOTICE
Lubricate all seals with petroleum jelly. Use
new seals when reassembling motor. Refer
to Parts Coverage.
Do not stretch seals before installing them.
