TM 10-3930-671-24 STEP 24 Remove the cam ring (Figure 3.24).  3.26b). FIGURE 3.24. STEP 25 Check and record the roller to roller dimension as   instructed   in   Step   3   of   reassembly   (Figure   5.3). Compare this dimension with that called for on the pump specification (Figure 3.25). FIGURE 3.25. STEP  26  Using  socket  head  wrench,  remove  the  leaf spring  adjusting  screw.  Remove  the  leaf  spring  (Figure 3.26a). In some cases, a  shim  is  used  beneath  the  leaf spring  to  limit  the  maximum  roller  to  roller  dimension  to .005"   above   the   specification.   If   a   shim   is   present, remove it at this time. Be sure to reinstall the shim during the reassembly. Remove   the   shoes   and   rollers   from   the   rotor   (Figure 3.2b). FIGURE 3.26b. Use   pressure   regulating   sleeve   extractor   to   push   the pumping   plungers   from   their   bore.   Handle    all    parts carefully    with    clean    hands    wet    with    calibrating    fluid (Figure 3.26c). FIGURE 3.26c.. STEP 27 Lift the rotor from the head (Figure 3.27). NOTE Do  not  handle  the  precision  ground  surface  of  the rotor. FIGURE 3.27. F-230
