Assembly After Repair
Use an extremely clean bench to work on and to place
parts during assembly. Be sure all injector parts, both
new and used, are spotlessly clean. Always use new
filters and gaskets when assembling an injector.
Install a new filter (1), dimple end down, slotted
end up in the inlet cavity of the injector body.
No filter is required on the outlet side.
Place a new gasket (2) on each filter cap (3).
Lubricate the threads with test oil and install in
the body (8). Tighten the caps to 75 ft lb (102
Purge the filter after installation by directing
compressed air through the inlet filter cap.
Install clean shipping cap on each filter cap to
prevent dirt entering.
Note the drill spot marks on the control rack
(10) and gear (9).
Hold the injector body (8) bottom end up and
slide the rack (10) through the hole in the
body. Push rack first through hole directly
above inlet filter cap. Look into the body bore
until drill marks can be seen. Place the gear
(9) in the injector body so that the marked
tooth is engaged between the two marked
teeth of the rack.
Place gear retainer (12) on top of gear (9).
Aline the locating pin in the bushing (13) with
the slot in the injector body (8). Slide end of
bushing into place.
Support the injector body (8), bottom end up in
holding fixture J22396.
(10) Place a new seal (22) and seal protector J29197 in a container with a small amount of test oil J26400
(11) Place the lubricated seal protector J29197 over the threads of the injector body (8). Place the seal (22)
over the nose of the protector. Slide the seal down the protector onto the shoulder of the injector body.
Do not allow the seal to roll or twist.
(12) Remove the protector.
