Injector Nozzles: Reassembly
NOTE:
Thoroughly clean all the disassembled parts with light clean oil. The needle must slide smoothly in the nozzle body. When the nozzle body is held vertically, and the needle is drawn out about 1/3 of the way and then released, it should fall down to the seat with its own weight.
To reassemble reverse disassembly procedures except when tightening the retaining nut. Tighten the retaining nut to 65 ft. lbs. (88 N.m). Then finish reassembly.
