7. Injector Removal — 38 mm (Tall) Yoke
with Stepped-Down Area
Use care when removing the unit injector
because the injector hold-down is not secure and
could fall off if not held in place.
a. Initially attempt to remove the unit
injector using the standard injector
puller (tool No. 9990006).
b. If the unit injector cannot be removed
using the standard puller, proceed with
using the heavy-duty puller (tool No.
J 48922) by positioning the forks of the
heavy-duty puller (tool No. J 48922)
under the lip of the unit injector, and
then secure the puller by sliding the
lock collar down over the forks. Remove
the injector from the cylinder head
using hand tools. The injector must be
lifted out along with the hold-down
yoke.

9. Remove and discard all injector nozzle
gaskets (flat washers) from injector tips or
bottoms of copper sleeves. Also, remove
and discard all O-rings and yoke screws.
New injector nozzle gaskets (flat washers),
O-rings and yoke screws are required for
installation.
If an injector nozzle gasket (flat washer) had been
used for the seal joint between the injector copper
sleeve and the injector, discard the used gasket
immediately after the injector is removed. A used
gasket must not be reused. When the injector is
removed, this gasket may come out attached to
the injector or it may remain in the bottom of the
injector sleeve.
