5-7. FUEL INJECTION PUMP - Continued.
d. Adjustment - Continued.
NOTE
The end of delivery is delayed or advanced by adding or removing shims (5) to injection pump (6). 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)
(f) Remove fuel shutoff clamp from fuel hose.
(g) After correction of shimming, repeat steps (a) and (b) for checking purposes.
(10) Adjustment of Delivery Lift. (Refer to figures 5-12 and 5-13).
NOTE
Delivery lift controls the quantity of fuel which is injected at full throttle (full load).
(a) Refer to figure 5-12 and with flywheel timing marks (2) (11.5 to 12.5 degrees) aligned with reference mark
(3), rotate dial gauge face to zero.
(b) Slowly rotate flywheel (1) in a clockwise direction when facing flywheel until dial gauge indicates 0.052 inch
(1.34 mm).
(c) Stop flywheel at position indicated in step (b).
Death or serious injury could occur if fuel is not handled carefully. Use in a well-ventilated area away
from open flame. Do not smoke.
(d) At this point, fuel should emerge again from spill pipe (4) of spill device (5)
NOTE
If fuel does not emerge, turn the extra fuel device. If results are not obtained, turn the extra fuel device
in the opposite direction.
