NOTICE Do not use a liquid cleaning agent to clean the armature assembly, field winding (coil) assembly, or pinion drive assembly. Liquids can damage these parts. Use only compressed air to clean them.
Personal injury can result from air pressure. Personal injury can result without following proper procedure. When using pressure air, wear a protective face shield and protective clothing. Maximum air pressure at the nozzle must be less than 205 kPa (30 psi) for cleaning purposes.
16. Clean the following items with compressed air: armature assembly field winding assembly pinion drive assembly housings solenoid assembly
To prevent personal injury or death from a possible explosion, make sure that all parts are thoroughly dry in order to eliminate formation of gas within the starter.
17. Wash parts such as screws, hardware, and the shaft of the armature with a commercially available cleaning agent. Dry all parts thoroughly. 18. Inspect all parts for wear and for damage. Copyright 1993 - 2020 Caterpillar Inc. All Rights Reserved. Private Network For SIS Licensees.
