The outside surfaces of the fuel pump unit must be clean and free of dirt before any service work is done. Dirt that enters the fuel pump unit will cause much damage.
1. Remove EGR switch cover (2) and solenoid (1).

SETSCREW INSTALLED
7. 8S7271 Setscrew.4. Use wrench (8) and tighten setscrew (7) until pin (6) is against pump housing. Install dial indicator (9) with 5P6531 Contact Point in collet (4). Move governor control lever (11) to the full load position. Make an adjustment to the dial indicator (move indicator up or down) until both hands are at zero. Tighten nut of collet only enough to hold indicator in position. Loosen lock (10) and turn bezel until large hand is on zero. Tighten lock (10). Use wrench (8) and turn setscrew (7) counterclockwise six turns.
ADJUSTMENT OF DIAL INDICATOR
8. 5P4205 Wrench. 9. 3P1567 Dial Indicator. 10. Lock. 11. Governor control lever.5. Release governor control lever (11), and move it to low idle position. Connect the wire clip end of a circuit tester to contact (Z) of EGR switch (12). Put the other end of tester to a good ground on fuel pump. Slowly move governor control lever (11) toward high idle position until light in circuit tester just comes on. Do this several times to make sure of the dimension on indicator (9). This dimension is the fuel setting. For the correct fuel setting, see the FUEL SETTING AND RELATED INFORMATION FICHE.
CHECK OF FUEL SETTING

Loosen locknut and turn screw (13) until dimension on indicator (9) is correct.7. When the adjustment is correct, tighten locknut. Check the adjustment by doing steps 1 through 5 again. If an adjustment is made to the fuel setting, check the adjustment for the contacts of the EGR switch. The same tools are used to adjust the contacts of the EGR switch that are used for fuel setting.Adjustment Of EGR Switch Contacts
Make reference to FUEL SETTING for the tools needed for this procedure.The fuel setting must be correct before an adjustment is made to the EGR switch contacts.1. Remove EGR switch cover (2) and solenoid (1).

CHECK OF CONTACT Y
12. EGR Switch. Y. EGR Contact.7. If the X or Y contact adjustment is not correct as shown in the CONTINUITY CHECK CHART, use a socket and make an adjustment. Turn the contacts clockwise to make the indicator reading smaller. After an adjustment is made, do Steps 5 and 6 again to check the setting. If too much adjustment is needed, check to see if the load stop pin is bent. If the load stop pin is bent, replace with a new part. When a new load stop pin is installed, adjust the fuel setting and EGR switch contacts X and Y.
