ARMY TM 9-6115-464-34AIR FORCE TO 35C2-3-445-2NAVY NAVFAC P-8-624-34(26)Lift off the cam ring (121 ). Check and record the roller-to-roller dimension as instructed in theassembly procedures. This dimension should be 1.9640 ± 0.0005 inches. Remove rollers (125),shoes (126), plungers (127), and leaf springs (124). Discard spring screws (123).(27)(28)CAUTIONDo not handle rotor shank. Failure to observe this caution could result in equipmentdamage.Remove governor weight retainer snap ring (118) with snap ring pliers.The flexible retaining ring (120) should be replaced whenever the pump is disassembled. Insert thesnap ring plier, in the closed position, under the edge of the retaining ring between only two of therivets. Spread the pliers while applying pressure in an upward direction. A slight twisting motion willsnap the ring off the rivet. Repeat the process until the retaining ring is free from all rivets. Discardthe retaining ring.d. Cleaning. Inspection. and Repair.(1)(2)(3)(4)Inspect all springs, bores, grooves, and seal seats for wear, breakage, or damage. Repair or replaceas necessary.Carefully inspect transfer pump blades for chipping on any edges, pitting, imbedded foreign particles,or wear on the rounded ends. Visually check flat surfaces for scores. Determine blade wear bymeasuring the length (0.538 inches minimum).CAUTIONDo not handle the rotor shank. Do not force the plungers into their bore. Failure toobserve this caution could result in equipment damage.While holding the rotor under fuel, insert the plungers into their bore. With thumb and forefinger overthe guide slots, tilt the rotor from side to side several times to insure complete freedom of movementof the plungers. Interchanging or reversing their individual positions may be necessary, as these aremated parts. Replace defective parts. If plungers are not visibly damaged, clean them with a softbrush and a lacquer removing solvent such as lacquer thinner or acetone.Examine the radii of the rotor which is contacted by the leaf springs, and the weight retainer for wear.Check all slots, charging and discharge parts of the hydraulic head for chipping or erosion of edges.Check the rotor shank for scratches.NOTEThe rotor and hydraulic head are matched parts and shall be replaced as a unit.(5)(6)(7)(8)(9)Check the vent wire in the hydraulic head air bleed passage for freedom of movement. If the wire isfree, flush the head and blow out all passages with clean, dry compressed air. If the wire is stuck,replace it after thoroughly cleaning the passages.Check each cam roller for freedom of rotation in its shoe. Check each shoe for chipping or wear onthe surface contacted by the leaf spring.Check the leaf springs for cracks, nicks, chipping, or distortion. Check for damage and wear alongrotor radii contact points and steps which retain roller shoes.Examine the retainer sockets of governor weight retainer and the pivot point of each governor weightfor evidence of wear or damage. Replace the flexible snap ring (120) of the weight retainer.Inspect the pivot points of the governor arm (86) pivot shaft for wear. Check the governor arm tabs atthe point which contacts the thrust sleeve. If either tab is worn flat, replace the governor arm.3-55
