TM 5-4310-393-14a. Slowly rotate the flywheel counterclockwise (when facing flywheel) until no fuel emerges from spillpipe on spill device 66503001.b.Continue to very slowly rotate flywheel while frequently blotting spill pipe with rag to absorb fuel, untilfuel just begins to weep from the spill pipe.NOTEThe position achieved above is theend of delivery. When the shim set isof the correct thickness, the timingmarks (3) on the fly-wheel (1) (11.5 to12.5 degrees) should align withreference mark (4).c.Block fuel hose (from fuel tank)using fuel shutoff clamp.d.If timing marks do not align withreference mark (4), rotate the outer face of the dialgauge 61208700 until "0" mark aligns with needleFIGURE 5-7. REFERENCE MARKSe.Slowly rotate the flywheel (1) in either direction to align timing marks of 11.5 to 12 5 degrees withreference mark (4) Gauge reading will indicate amount of re-shimming requiredNOTEThe end of delivery is delayed oradvanced by adding or removingshims (Figure 5-8, Item 1) to injectionpump (2). The general rule forshimming is as follows: More shims= end of delivery later (lower numberof degrees). Less shims = end ofdelivery earlier (higher number ofdegrees).f.Remove fuel shutoff clamp from fuelhose.FIGURE 5-8. PLACING SHIMSg.After correction of shimming, repeat steps 1 and 2.3.Adjustment of Delivery Lift. Adjust for delivery lift as follows:NOTEDelivery lift controls the quantity of fuel which is injected at full throttle. Thedelivery lift measurement for a particular engine is stamped on the engine data andserial number plate.a.With flywheel timing marks (Figure 5-9, Item 2) (11 5 to 12 5 degrees) aligned with reference mark(3), rotate dial gauge 61208700 face to zero.5-12
