ASSEMBLY

NOTE

During assembly, the addition or removal of spring adjusting shims

(to obtain the correct gauge pressure reading on the nozzle tester)

may require various shim combinations available in the shim sets.

The nozzle assembly must be completely assembled, torque tightened

and checked again on the nozzle tester to assure proper spacer

combination and pressure reading.

This procedure may have to be

repeated several times before achieving a satisfactory reading.

1. Install fuel inlet fitting (5) into body (6) and

torque to 70-75 foot-pounds (95-102 N
