TM 10-4320-310-14 6-9. REPLACE/ADJUST INJECTION PUMP (Continued) NOTE The position achieved above is the end of delivery. If the shim pack is of the correct thickness, the timing marks on flywheel (1) (11.5 to 12.5 degrees) should align with reference mark (4). 3 Block fuel hose (from fuel tank) using a C-clamp. 4 If timing marks do not align with reference mark (4), rotate outer face of dial gauge until "0" mark aligns with needle. 5 Slowly rotate flywheel (1) in either direction to align timing marks of 11.5 to 12.5 degrees with reference mark (4). Gauge reading will indicate amount of reshimming (as necessary). NOTE The end of delivery is delayed or advanced by adding or removing shims (1) to Injection pump (2). The general rule for shimming Is as follows: More shims = end of delivery later (lower number of degrees). Less shims = end of delivery earlier (higher number of degrees). 6 Remove C-clamp from fuel hose. 7 After correction of shimming, repeat steps 1 and 2 for checking purposes. 6-32
