CLEANING
Do not steam clean drive parts that have ground and
polished surfaces such as gears, bearings, and shafts.
All parts should be disassembled before cleaning.
These parts should be cleaned in a suitable solvent.
Parts should be thoroughly dried immediately after
cleaning. Use soft, clean, lintless rags. Parts may be
dried with compressed air. Do not allow the bearings to
spin while drying them with compressed air.
INSPECTIO N
It is critica l to ca re fully and thoroughly inspect all
drive unit parts before assembly.
Thorough inspection of the drive parts for wear or
stress and subsequent replacement of worn parts will
eliminate costly drive component repair after reassem­
bly.
