Adjusting the fuel injection timing to
compensate for the difference in pump timing
index numbers:
Calculation Example
Timing Index Number
Original injection pump=
6.8
Replacement injection pump=
7.3
Difference=
+0.5
If the difference between the timing index
numbers is a positive number, the fuel
injection pump mounting position must be
advanced (Figure 19, (2)) (rotated away from
the engine) as compared to the "standard
mark" (Figure 19, (1)) by the calculated
positive amount, adjust the fuel injection
pump to the calculated value.
If the difference between the timing index
numbers is a negative number, the
replacement injection pump must be retarded
(Figure 19, (3)) (rotated toward the engine) by
the calculated negative amount.
Each mark on the timing sticker represents
0.50 timing change. The above calculated
difference indicates that the replacement fuel
injection pump is to be installed at +0.5°
(advanced) from the "Standard Mark" (Figure
19, (1)) on the timing sticker.
IMPORTANT
When installing a new or repaired fuel injection
pump, it is important to add engine oil to the fuel
injection pump to provide lubrication for initial
start-up. Add 5-7 oz (150-200 cc) of clean
engine oil to the fuel injection pump at the fill plug
located in the upper outside section of the
governor housing.
