FUEL INJECTOR AND NOZZLE TEST - Continued
NOTE
If leakage occurs at the nut for the fuel supply line, make sure that the fuel supply line and
the nut for the fuel supply line are correctly aligned with the inlet connection of the fuel injector
nozzle.
2.
Loosen the nut (Figure 1, Item 3) for the fuel supply line (Figure 1, Item 1) at each fuel injector nozzle
(Figure 1, Item 2).
NOTE
Listen for the low idle to decrease or become rough at each engine cylinder.
3.
The fuel injector nozzle (Figure 1, Item 2) is faulty and should be replaced when the fuel supply line
(Figure 1, Item 1) is loosened and the following events occur:
a.
The engine rpm does not decrease.
b.
The engine does not idle roughly.
4.
If faulty, replace fuel injector nozzle (WP 0109) or (WP 0110).
CAUTION
Do not over-tighten the nut for the fuel supply line. If nut is tightened more, fuel line may
become restricted or threads of fuel injector nozzle and nut may be damaged.
5.
Tighten each nut to 176.4 lb-in. (20 Nm).
