TM 5-3895-370-14&P
a.
When cleaning ball or roller bearings, place in a basket and suspend in a container of drycleaning solvent, (item
50, Appendix E). If necessary, use a brush (item 5, Appendix E) to remove caked grease or chips. Avoid rotating
bearings before solid particles are removed to prevent damaging races and balls.
b.
Do not clean preformed packings or other rubber parts in drycleaning solvent. Wipe with a clean, dry, lint-free
cloth (item 12, Appendix E).
c.
Electrical parts such as coils, connectors, switches, and insulated wiring should not be soaked or sprayed with
cleaning solutions. Clean these parts with a clean, dry cloth moistened with drycleaning solvent (item 50, Appendix E).
d.
For exterior cleaning of frame and structural components, use detergent (item 19, Appendix E) in a solution as
recommended on the container. Leave application on items surface for approximately 10 minutes before rinsing. Rinse
with hot or cold water under pressure. If available, use hot water under 80 to 120 psi (36 54 kPa) pressure. An ordinary
garden hose may be used if no other equipment is available. If pressurized water supply is not available, wash painted
surfaces with a solution of 1/4 cup soap chips (item 10, Appendix E) to one gallon of water.
CAUTION
Do not use gasoline, diesel fuel, or other petroleum base products to clean or
preserve hydraulic components. Use of petroleum based products can change the
lubricating quality of hydraulic fluid and cause failure or damage to equipment.
e.
When cleaning hydraulic system components, use petroleum-free solvents. Clean and dry parts thoroughly to
make sure no residue remains. If preservative is required before reassembly, apply a light film of hydraulic fluid (item 21,
Appendix E).
4-21. REMOVAL AND DISASSEMBLY OF COMPONENTS.
a.
Before removal of any electrical component, disconnect battery ground cables.
b.
Ensure that adequate clearance is available for removal of the component. Disassemble the vehicle to the extent
necessary to provide adequate working clearance.
WARNING
All personnel must stand clear during lifting operations. A swinging or shifting
load may cause injury or death to personnel.
c.
Use a chain hoist, jack, or other aid when lifting heavier components. Lifting device should be positioned and
attached to components to remove all strain from mounting hardware, before last supporting piece of hardware is
removed.
d.
Discard preformed packings, gaskets, seals, and similar material when removed. Be sure that all traces of oil,
gaskets, and sealants are removed. When possible, use wood or plastic probes and scrapers to prevent damage to
machined surfaces.
