12. Repeat step 11 for the second injector. Account for
a flame washer and copper washer for each injec-
tor.
Servicing
Proper servicing of fuel injection components requires
a number of special instruments, special training, and
an extremely clean environment (clean room); there-
fore, Arctic Cat recommends injector service be per-
formed by a qualified diesel injection service facility.
Installing
1. Thoroughly clean the injector bores in the cylinder
head; then dry with compressed air.

clean injector bores and seating surfaces.
2. Clean the unit injector with a soft wire brush being
careful not to damage the injector tip.

3. Measure the injector nozzle protrusion (A). Mea-
surement should be 6.80-7.05 mm (0.268-0.277
in.). Excessive protrusion may be corrected by
installing supplemental washers available in 0.25
mm (0.001 in.) sizes along with the standard cop-
per washers (B).

4. Clean the fire ring sealing surface in the cylinder
head taking care not to damage the pre-combus-
tion cup ring nut.
CAUTION
DO NOT loosen the jam nut or the injector timing
adjustment screw. This will require timing the
injector.
! WARNING
Always wear safety glasses when using compressed
air.
