ARMY TM 9-2815-256-24 AIR FORCE TO 38G1-96-2 MARINE CORPS TM 2815-24/5 FIGURE 3-89.  Delivery Valve Replacement CAUTION Always use a new delivery valve stop (35, FIGURE 3-73).  Installation of a used stop can result in leakage and low output at cranking speed. CAUTION Excessive   tightening   of   screw   (34)   can   cause   seizure   of   hydraulic   head   and   rotor   assembly. Insufficient torque may cause leaking and hard starting. NOTE Tighten screw (34) 120 to 125 in-lbs.  (13.6 to 14.1 Nm). j. Install  delivery  valve  spring  (36)  and  new  delivery  valve  stop  (35)  in  rotor  bore.    Using  hex  end  of  extractor (13383), install screw (34). NOTE' Tighten connectors 58 to 66 ft-lbs (78.6 to 89.5 Nm). k. If removed, install six new fuel connectors (47) in head. I. If removed, install plungers (29) in their bores and check for freedom of movement.  Install four shoes (28) and rollers (27) on rotor, refer to FIGURE 3-90. m. Remove rotor from holding fixture and submerge it in clean calibrating oil. CAUTION Do  not  force  Plungers  into  bore.    Never  attempt  to  press  a  roller  into  a  shoe  from  outer  edges,  as groove width at this point is less than roller outside diameter and shoe breakage can result. 3-108
