Adjust Fuel Injection Nozzles adjustment

⚠ Do not manually bottom the valve with excessive force; bending of the valve may result.

Tools: JDG949 Nozzle Wrench, JDG1515-2 Pressure Adjustment Screw Lock Nut Tool, JDG1522 Pressure Adjustment Screw Tool, JDG1521 Spring Chamber Cap Wrench

  1. Remove nozzle from tester and install in holding fixture.
  2. Remove lift adjusting lock nut.
  3. Loosen pressure adjusting screw lock nut using JDG949 Nozzle Wrench.
  4. Reconnect nozzle to tester with tip pointing downward.
  5. Back out lift adjusting screw two or three turns to prevent bottoming.
  6. Turn pressure adjusting screw in (clockwise) to increase opening pressure or out to decrease.
  7. Remove nozzle and secure in holding fixture; tighten pressure adjusting screw lock nut to 10 N•m (7 lb-ft).
  8. Adjust valve lift: turn lift adjusting screw in until valve ceases to open (conventional nozzle).
  9. Turn lift adjusting screw out 3/4 turn counterclockwise (based on zero lift); 1/8 turn tolerance permissible.
  10. Tighten lift adjusting screw lock nut to 5 N•m (3.5 lb-ft).
  11. Recheck nozzle opening pressure and chatter.
Adjusting Variable Speed (Droop) on Generator Set Engines (Stanadyne Mechanical Injection Pumps Only) adjustment
  1. Warm engine to normal operating temperature.
  2. When necessary, disconnect throttle linkage or cable.
  3. Adjust slow idle and adjust fast idle speed when necessary.
  4. Run engine at fast idle, then apply load until reaching rated speed.
  5. Check power. Adjust with the screw if needed.
  6. Remove load from engine.
  7. Again check and adjust fast idle if the droop screw has been turned.
  8. Repeat procedure until both the engine power and the fast idle speed are correct.
  9. Reinstall throttle linkage if previously removed.
Check and Adjust Rotary Injection Pump Dynamic Timing adjustment

⚠ Stop engine prior to making timing adjustments; injection pump can seize if adjustment is made with engine running.

Tools: JT07158 (FKM10429A) TIME TRAC Kit, JT07177 Clamp-On Transducer, JT07172 Transducer Cable, JDG793 or JDG821 Magnetic Pick-Up Adapter, JDE81-4 or JDG1571 Timing Pin

  1. Install JT07158 (or FKM10429A) TIME TRAC Kit.
  2. Install transducer or in-line SOI sensor on No. 1 fuel injection line at nozzle end; use No. 4 or No. 6 line if access restricted.
  3. Install magnetic pick-up in flywheel timing hole with 0.64 mm (0.025 in.) air gap; do not stop engine at TDC.
  4. Engine OFF; push ON/CLEAR; select MAG PROBE, set Trig Level to 70%, press ENTER.
  5. Set Offset to 0 degrees and press ENTER.
  6. Start engine, press ENTER; run engine at 1300 rpm, press ENTER to calibrate.
  7. Warm engine to normal operating temperature; check slow and fast idle rpm; adjust as necessary.
  8. Run engine at wide open throttle and load engine down gradually to rated speed rpm.
  9. Record engine speed and timing degrees; compare to Section 06, Group 210 or machine technical manual.
  10. Stop engine; loosen injection pump mounting flange nuts and adjust pump timing.
  11. To advance timing rotate top of pump clockwise (viewed from rear/flywheel end); to retard rotate counterclockwise.
  12. Tighten injection pump mounting flange nuts to 27 N•m (20 lb-ft).
  13. Start engine and recheck dynamic timing; adjust as needed.
  14. Grind away original front plate timing mark and stamp a new mark aligned with injection pump flange mark.
Check and Adjust Slow Idle Speed—Denso Fuel Injection Pump adjustment
