alignment hole (3) and into the cylinder block

target area (5). If rod is at edge of target
area, two methods may be tried to center the
rod into the target area.
a. Preferred — Loosen nozzle set screw.
A slight adjustment can then be made
to center the rod within the target area.
Following adjustment, retorque set
screw to 15 lb-ft (20 N폷m).
b. Alternate (pre-1991 only) — It is
permissible to bend the hooked end of
the nozzle tube only slightly to bring
the rod fully within 1/8 inch of the target
area. If more than 1/8 inch out of target
area, replace nozzle.
