See Figure 8-8. WARNING Dry cleaning solvent, PD-680, Type Ill, or equivalent, is flammable and moderately toxic to the skin, eyes, and respiratory tract. Assure adequate ventilation. Skin, eye, and respiratory protection is required to avoid injury to personnel. WARNING Compressed air used for cleaning or drying can create airborne particles that may enter the eyes. Pressure shall not exceed 30 psi (207 kPa). Wearing of goggles is required to avoid injury to personnel. a. Clean all parts using cleaning solvent PD-680, Type Ill, or equivalent, and dry with compressed air. b. Inspect all threaded parts for stripped or damaged threads. Replace as necessary. c. Inspect the carbon bearings (22), idle shaft (24), and drive shaft (26) for scoring of the friction surfaces. Replace as necessary. d. Inspect the cover (12) and body (29) for damage, and ensure that the mating surfaces are not scored or grooved. Replace as necessary. e. Check the spring (20) for signs of breakage or distortion. Replace as necessary. f. Check the grommets (3) for signs of damage or deterioration. Replace as necessary. 8-18. PRELUBE PUMP B3 ASSEMBLY. a. Install the lip seal (10, Figure 8-8) in the cover (12). b. Press the carbon bearings (22) into the cover (12) and the body (29), if removed. c. Press the gear (25) on the drive shaft (26), and press the pin (27) in the gear. d. Press the gear (23) on the file shaft (24). e. Lubricate the idle shaft (24) and gear (23), and the drive shaft (26) and gear (25), with dean lubricating oil, such as MIL-L-2104, and install in the cover (12). Ensure that the idle shaft (24) and gear (23), and the drive shaft (26) and gear (25), rotate freely in the carbon bearings (22). 8-15
