CLEANING AND INSPECTION
WARNING
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low toxic
material. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in
well-ventilated areas. Keep away from open flames and other sources of ignition.
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure
when drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when cleaning compo-
nents. DO NOT direct compressed air against human skin. Failure to follow this warning may result in
injury or death. Make sure air stream is directed away from user and other personnel in the area. To pre-
vent injury, user must wear eye protection.
CAUTION
Do not use dirty cleaning solvent P-D-680 to clean transmission control valve assemblies and parts. Use
only clean, fresh solvent that will leave no residue. Failure to follow this procedure could result in damage to
equipment.
1.
Remove all preformed packing from mounting surfaces.
2.
Clean all parts with solvent.
3.
Dry parts with compressed air.
CAUTION
All parts are critical to the operation of the transmission control valve assembly and must be inspected
closely. If defective parts are assembled, the transmission will not operate properly, resulting in damage to
equipment.
4.
Inspect all parts for damage and replace if damaged.
