ARMY TM 9-6115-464-34 AIR FORCE TO 35C2-3-446-2 NAVY NAVFAC P-8-624-34 (10) (11) (12) (13) (14) (15) Examine the junction points of the metering valve pin hole in the linkage hook, throttle lever, shutoff cam, and shutoff lever for looseness and burrs. Check the metering valve body for wear. Ascertain that the metering valve arm is well seated and there is no radial movement of the arm on the valve. Check the metering valve arm pin for wear or looseness. Carefully inspect the bore and edges of all flat surfaces of the cam. If evidence of spatting or flaking out exists, replace the cam. NOTE Since only the working portions of the cam lobes on the bore are ground, the tool marks between lobes should not be considered as damage. The cam finish is mottled from heat treatment rather than operation. Visually inspect the drive shaft for undue wear or cracking. Check the diameter where the thrust sleeve slides for scores. Check for smoothness of seal grooves. They must be absolutely smooth. Check the regulating piston for freedom of movement in the end plate sleeve. Check all threads for damage. The filter element should bear no evidence of damage. Clean all dirt or rust from the element. CAUTION Check for tightness of the orifice plate. Replace adjusting plug if plate is loose. Failure to observe this caution could result in equipment damage. Check that the damper piston (87) moves freely in the damper barrel (88). Inspect for chipping of piston or scratches to the piston and damper barrel bore. The bleed orifice should allow free flow when the piston is inserted. Replace components as necessary. e. Assemblv. NOTE All parts should be flushed in clean oil as they are assembled. Replace all seals and gaskets. CAUTION Install piston seal dry. Do not use grease. Failure to observe this caution could result in equipment damage. (1) Insert regulating piston seal (62) into the lower end of the regulating sleeve assembly (55) far enough to expose retaining ring groove. Install retaining ring (59). (2) Install regulating piston (61) and spring (60) into the sleeve making sure that the piston slides to the bottom of the sleeve bore without binding. (3) Install end plate adjusting plug (54) into the sleeve until all threads are just below port “A”. CAUTION Do not exceed this position as excessive transfer pump pressure could occur. Failure to observe this caution could result in equipment damage. (4) Insert regulating sleeve assembly into the bore in end plate (66). (5) Fit the transfer pump thrust plate (67) on the end plate (66). 3-56
