Install timing tool (7) on drive adapter (5). Install adapter (6) on timing tool (7). Adapter (6) is used to rotate timing tool (7). Adapter (6) also rotates the drive shaft of the fuel injection pump. To rotate the adapter, a handle must be made. Use three set screws in adapter (6) in order to connect the handle to adapter (6).
Adjust the automatic timing advance unit (if equipped). The automatic timing advance unit is a device that is used during fuel injection timing. Refer to Testing and Adjusting, "Automatic Timing Advance Unit - Test" for the procedure to adjust the automatic timing advance unit.
When the pump plunger is at the lowest position, set the dial indicator to zero. The bar will have no tension as the pump is turned to this position.
The drive shaft of the pump is turned clockwise until the pointer on the gauge indicates 1 mm (0.039 inch). The fuel injection pump is viewed from the drive end. Hold the shaft in this position and tighten locking bolt (3).
Loosen locking screw (10). Move the setting block (not shown) until the pointer aligns with the center of the top outer slot in the pump flange. Tighten locking screw (10).
Loosen locking screw (8) for pointer (9). Slide the pointer forward until the slot in the pointer covers the pump flange. Tighten locking screw (8).
Hold timing tool (7) against the direction of the pump rotation in order to remove backlash. Place a mark on the pump flange along the slot in the pointer.
Loosen locking screw (8) for pointer (9). Slide the pointer rearward until the slot in the pointer covers half of the pump flange. Tighten locking screw (8). Note: The automatic timing advance unit (if equipped) must be energized before the timing is set. Refer to Testing and Adjusting, "Automatic Timing Advance Unit - Test" for the procedure to adjust the automatic timing advance unit.
Remove the adapter and the timing tool. The angle that is indicated on the tool should be increased by 50 degrees.
Loosen locking bolt (3) on the fuel injection pump. Allow the pump plunger to return to the lowest position. The dial indicator should return to zero.
Install timing tool (7) and adapter (6) on the pump drive.
Rotate the timing tool counterclockwise until the slot in the pointer is aligned with the mark on the pump flange. Tighten locking bolt (3). Ensure
