Operation sequence
1. Turn the prestroke actuator OFF.
2. 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.

1. When installing the pre-stroke actuator on the pump, first tighten the installation bolts loosely, then move the actuator fully counterclockwise (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 clockwise 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 output characteristics
1. Rack limit adjustment
(1)Measure the rack position R2 for PWM a2%.
(2)Confirm that it is within the range R2 = 15+-1 mm.
(3)Measure the rack position R1 at PWM a %.
(4)Confirm that it is within the range R2 - R1 = 10+-0.1 mm.
2. Check the limp home operation.
(1)Move the switch box's limp home switch to the limp home side.
(2)Confirm rack position L1 (mm ) and L2 (mm) for PWM in the above table.
3. Check the pull down operation.
(1)Confirm that the rack position is 19 mm at PWM B%.
(2)In the conditions described in the above table, move the switch box's pull down switch to the pull down side and confirm that the rack position momentarily becomes 1 mm or less.

PROBLEM
The existing 162-9612 Fuel Transfer Pump Group that is part of the 162-9608 Unit Injector Hydraulic Pump Group can fail on certain 3126B Gen Set Engines. The failure has been associated to undersized splines inside of the fuel transfer pump. This may cause an accelerated wear to the splines of the fuel transfer pump and the unit injector hydraulic pump.

In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 3% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
ACTION REQUIRED
Replace the failed 162-9608 Unit Injector Hydraulic Pump Group with a 20R-0122 Unit Injector Hydraulic Pump Group.
Note: Refer to Image1 to determine that the correct part is being installed. The correct fuel transfer pumps will have an "H" stamped in the part.
Refer to SENR9589, Disassembly and Assembly for instructions on the removal and installation of the unit injector hydraulic pump.
