Removal and installation of each fuel injector is performed the
same way. Cylinder number two is shown.
REMOVAL
1.
Loosen nuts (1), (4), (15), and (20) and remove fuel pressure pipe assemblies (2) and (3)
from fuel injectors (9) and (19) and injection pump fitting (13) and (14).
2.
Remove fuel return hose (16) from hose nipple (17).
3.
Remove fluid passage bolt (21), gasket (18), hose nipple (17), and gasket (18) from fuel injector (9).
Discard gaskets (18).
4.
Remove nut (5), spring washer (6), spacer (7), and fuel injector clamp (8) from stud (11). Discard

Make sure tapered side of spacer is toward injector clamp and that
tapered side of injector clamp is facing up.
1.
Install new gasket (10) on fuel injector (9) and install fuel injector (9) in cylinder number two with
fuel injector clamp (8), spacer (7), new spring washer (6), and nut (5). Tighten nut (5) to 17 ft-lb
(23 Nm).
2.
Install new gasket (18), hose nipple (17), new gasket (18), and fluid passage bolt (21) on fuel
