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 refer-
ence mark (4).
Block fuel hose (from fuel tank) using fuel
shutoff clamp 668 383 00.
If timing marks do not align with reference
mark (4), rotate outer face of dial gage
612 087 00 until “0” mark aligns with
needle.
Slowly rotate flywheel (1) in either direction
to align timing marks of 11.5 to 12.5 degrees
with reference mark (4). Gage reading will
indicate amount of reshimming (as necessary).
NOTE
The end of delivery is delayed or advanced by adding or re-
moving 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)
Remove fuel shutoff clamp 668 383 00
from fuel hose.
After correction of shimming, repeat steps
1 and 2 for checking purposes.
