(6) Connect wiring to engine (see Figure 4-2).
(7) Connect air lines to engine (see Figure 4-4).
(8) Connect fuel return line to no. 1 injector nozzle and fuel tank.
(9) Connect the fuel line to the water trap and the fuel pump (see figure 4-11).
4-41. OIL FILTER ELEMENT REPLACEMENT.
a. Unscrew the filter element (see Figure 4-12 and 5, Appendix F, Figure 61) from the filter head (2).
b. Check that the threaded adapter is secure in the filter head (2) and discard the old filter element (5). Clean
the filter head.
c. Lightly oil the top seal of the new filter element (5) using clean engine lubricating oil.
d. Screw the new filter element (5) on to the filter head (2) until the filter element seal just touches the head and
then tighten by hand. If the filter element is over tightened, removing it may be difficult.
Figure 4-12. Oil Filter
e. As the filter element (5) will normally be changed at the same time as the engine lubricating oil, refill the
crankcase with oil, run the engine, and check for oil leaks. Check the oil level after running the engine and
top up as necessary (see Chapter 3, Section I).
4-42. FUEL FILTER ELEMENTS REPLACEMENT.
a. Replacement (See Figure 4-13).
There are two fuel filters used with the water distributor engine. One is
mounted on the engine and the second is attached to the water distributor
frame under the engine. The following procedure covers both filter elements.
Change both filter elements at the same time. Never change only one.
(1) Remove the filter bowl mounting screw and separate the filter bowl (28, Appendix F, Figure 71) and filter
element (30) from the head casting.
Do not attempt to clean or reuse the filter elements or equipment could be damaged.
(2) Discard gaskets and filter element (30).
(3) Replace filter element (30) and gaskets.
Ensure that the filter bowl gaskets are alined correctly before installing the filter
bowl to prevent damage to equipment.
(4) Attach the filter bowl (28) to the head casting and install mounting screw.
(5) Prime fuel system.
b. Priming Fuel System.
Do not start the engine before priming the fuel system and bleeding air present In
the fuel or damage may occur to equipment.
(1) Remove the vent plug (11) from the primary fuel filter vent (see Figure 4-13).
