2) General Procedures:

a) Cleaning of Parts: All disassembled components shall be thoroughly cleaned and kept clean throughout entire reconditioning process. Cleaning ensures effective inspection for wear, damaged and serviceability of components. Electrical components shall not be immersed in solvent or subjected to liquid or vapor degreaser.

b) Identification: Establish proper controls or identification to maintain relationship of matched parts.

c) Handle With Care: Use utmost care when handling parts and during cleaning and reconditioning operations. Nicks, scratches, dents, or burrs can prevent proper assembly or cause malfunction after assembly.

APPENDIX C - CLEANING PROCEDURES

APPENDIX C-2

Compressed air can injure you and others.

1) Vacuum loose dirt from rotor, stator, and bearing bracket assemblies.

If vacuum is not available, use dry, filtered compressed air, 20 psi maximum to carefully blow out loose dirt.

WARNING

Alcohol and naptha fumes are toxic and flammable.

Solvent fumes can burn and could poison you.

Do not rub varnished parts, particularly windings, hard enough to remove varnish. Never soak components with windings in cleaning solvent as soaking may soften or remove varnish

2) To clean parts containing windings and/or insulation, use lint-free cloth or soft bristle brush moistened with solvent such as isopropyl alcohol or naptha. Thoroughly dry after cleaning with dry, filtered compressed air, 20 psi maximum.

3) Clean metal parts, other than ball bearings by immersion in degreaser.

Clean ball bearings using clean wiping rag.
