GENERAL MAINTENANCE PROCEDURES

GENERAL CLEANING PROCEDURES

Cleaning procedures are the same for most parts and components that make up the vehicle

subassemblies. Great care and effort are required in all cleaning operations. Dirt and foreign material

can jeopardize satisfactory vehicle operation and maintenance.

The following guidelines apply to all cleaning operations:

Clean all parts before inspection, after repair, and before assembly.

Keep hands free of large amounts grease, which can collect dust and grit.

After cleaning, wrap or cover all parts with plastic or paper to protect them from dust and/or dirt.

NOTE

All electrical equipment and other parts that can be damaged

by steam cleaning or moisture must be removed and all

openings must be covered before cleaning. Dry parts with

compressed air.

Place disassembled parts in wire baskets for cleaning. Dry and cover all cleaned parts and inspect

or repair as necessary. All parts subject to rusting must be oiled and wrapped in paper or plastic to

avoid dirt and/or dust settling on them. Keep all subassembly parts together and avoid mixing

parts.

WARNING

Improper cleaning methods and use of unauthorized cleaning

solvents may cause damage to equipment or injury to

personnel.

Compressed air source must not exceed 30 psi (207 kPa). Wear

eyeshields when cleaning with compressed air. Failure to wear

eyeshields may result in injury to personnel.

Clean inner and outer surfaces of castings and all areas likely to collect grease and oil with

cleaning solvents. Use a stiff brush to remove sludge and gum deposits. Use compressed air to blow

out all tapped screw holes and to dry castings after cleaning.

Particular attention must be given to all oil passages in castings and machined parts. Oil passages

must be kept clean and free of obstructions. Clean passages with wire probes to break up any

sludge or gum deposits. Wash passages by flushing with cleaning solvents. Dry passages with

compressed air.

Clean electrical cables and flexible hoses with soap and water. Allow to air dry.
