Turn the camshaft as far as the No.1 cylinder's beginning of injection position. 3. Check that the pointer alignment mark of the injection pump and the alignment mark of the flywheel are matching. 4. If they are not matching, erase the alignment mark on the flywheel side, and stamp an alignment mark on the flywheel position that matches with the pointer side alignment mark. 5. Check again that the coupling's key groove position is in the No.1 cylinder's beginning of injection position.

A:Sealing position B:Pre-stroke actuator 1. When installing the pre-stroke actuator on the pump, first tighten the installation bolts loosely, then move the actuator fully clockwise (viewed from the drive side). Temporary tightening torque: 1 - 1.5 N.m (0.1 - 0.15 kgf.m) 2. Move the actuator in the counterclockwise direction when viewed from the drive side, and adjust so that it becomes the adjustment point of the adjustment value. Then tighten it. Tightening torque: 7^9 N.m (0.7^0.9 kgf.m) 3. After prestroke actuator installation adjustment, simultaneously stamp both the actuator side and housing side.

Rack sensor adjustment (-0620) (1)Fix the speed control lever at the full position (2)Set the speed to N1 r/min. (If the boost compensator is provided, apply boost pressure.) (3)Adjust the bobbin (A) so that the rack sensor's output voltage is VR+-0.01. (4)At that time, rack position must be Ra. (5)Apply G at two places.

0000002301 SPEED SENSOR

(A) Flyweight projection (B) Pickup sensor (c) Lock nut Speed sensor installation (1)Install the speed sensor so that the clearance between the sensor and the flyweight projection is L. (This gap is the gap when the pickup sensor is returned 1 turn from where it contacts the flyweight tooth.)

Information:

Use Again - if wear on contact surfaces cannot be felt with a seal pick.

Illustration 47 g06346580
Riser shaft.
Use Again - if there is no wear step on the shaft, which can be felt with a seal pick. If a step is present, it will generally occur near the center of the shaft.

Normal wear on pin at end of riser shaft.
Use Again

Flyweight toe wear.
Do Not Use Again
Illustration 52 g06346602
Flyweight toe wear.
Do Not Use Again - if there are any signs of "flat spots". Worn flyweight toes may be highly polished so that flat spots are difficult to feel. Hold the flyweight toe surface in bright light and watch for changes in reflection in worn areas. Use a new flyweight toe for comparison.
Illustration 53 g06346609
Acceptable wear on flyweight dowel.
Use Again - if wear cannot be felt with a seal pick.
Illustration 54 g06346611
Heavy wear on flyweight dowel.
Do Not Use AgainNote: Examine the dowel seating area on the flyweight carrier. If there is any apparent wear, reinstall dowels in the unused positions, 90 degrees from original position.Bearing Assembly

The bearing (white collar) shown in position on the FARC diaphragm retainer (Type V, VI, and VII Governors) shows wear.
Do Not Use AgainGovernor Spring Seat
Illustration 56 g06346615
Governor spring seat with typical wear.
Use Again - if there are no gouges to surfaces (1) on the spring seating area.Spring Pack
Illustration 57 g06346618
End view of governor spring pack.
Use Again - after realignment.Note the off-center position of the internal springs with respect to the outside spring. This can cause governor instability, which results in surging. Rotate the springs on their seat so that the inner springs are aligned (centered) with respect to the outer spring. Remove sharp edges (A) from the inside diameter of the flat surface on the springs to ensure springs seat properly.
