8. One at a time, loosen the high pressure fuel injec-
tor line nuts at the injector while cranking the
engine.
9. When bubbles disappear, tighten the fuel line nuts.
Repeat Steps 6 and 7 for the remaining fuel injec-
tion lines.
10. When all the lines have been purged and the
engine is running, listen to the engine. If it sounds
like it’s missing, repeat Steps 6 and 7 for all the
injection lines.
ENGINE REMOVAL
(See Figures 3D-6 to 3D-8)
1. Disconnect and tag all electrical connections at the
engine.
2. Remove the fuel line from engine.
3. Disconnect air cleaner and support rods (see Fig-
ure 3D-6).
4. Disconnect the throttle cable at the fuel injection
pump (Figure 3D-7).
5. Remove the exhaust pipe and radiator shroud de-
scribed in preceding paragraphs (see Figure 3D-2
and 3D-3).
6. Tag and remove hydraulic lines from 4 wheel drive
valve block (see Figure 3D-6).
7. Remove 4 wheel drive valve block.
8. Remove the bolts (1) and lockwashers (2) that
