(9) Adjustment of Delivery End. (Refer to figure 5-11).
NOTE
The position of Top Dead Center (TDC) (2) and end of delivery (3) are marked on the flywheel. The
corresponding (alignment) mark (4) is on the right upper side of the crankcase.
(a) Slowly rotate flywheel counterclockwise (when facing flywheel) until no fuel emerges from spill pipe on spill
device.
(b) Continue to very slowly rotate flywheel, while frequently blotting spill pipe with rag to absorb fuel, until fuel
just begins to weep from spill pipe.
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 (2).
Figure 5-11. Fuel Injection Pump Delivery and Adjustment.
(c) Block fuel hose (from fuel tank) using fuel shutoff clamp.
(d) If timing marks do not align with reference mark (2), rotate outer face of dial gauge until "O" mark aligns with
needle.
(e) Slowly rotate flywheel (1) in either direction to align timing marks of 11.5 to 12.5 degrees with reference mark
(2). Gauge reading will indicate amount of reshimming (as necessary).
