Leg Prop Assembly Lubrication. The rear leg prop assembly is a modification to the standard M116A1
trailer and, as such, does not appear in the associated LO. Semiannually lubricate leg prop assembly as follows:
Clean parts in a well-ventilated area. Avoid inhalation of solvent fumes and prolonged
exposure of skin to cleaning solvent. Wash exposed skin thoroughly. Dry cleaning
solvent (PD-680) used to clean parts is potentially dangerous to personnel and property.
Do not use near open flame or excessive heat. Flash point of solvent is 100°F to 138°F
(38°C to 59°C).
Clean hydraulic lubrication fitting and area around lubrication points with PD-680 or equivalent.
Inject sufficient GAA grease into hydraulic fitting to lubricate screw threads inside leg prop assembly
