Rack sensor adjustment
1. Flange type rack sensor (rack sensor adjustment -5*20)
(1)These types of rack sensors do not need adjustment. Confirm the performance with the following procedures.
(2)Mount the rack sensor main body to the pump main body.
(3)Fix the pump lever at full.
(4)At supply voltage V1, pump speed N1 and rack position Ra, confirm that the amp's output voltage is Vist.
(5)Move the pump lever two or three times.
(6)Set again to full.
(7)Confirm that the amplifier output voltage is Vist.
(8)Fix the caution plate to the upper part of the rack sensor.
(For those without the caution plate instructions, make sure the nameplate of the rack sensor carries the "Don't hold here" caution.)
(9)Apply red paint to the rack sensor mounting bolts (2 places).

Information:
Start By:a. remove fuel injection lines 1. Remove the plug, and move the race until Tool (A) can be installed to hold the rack in the center position. The rack must be in the center position to remove the fuel injection pumps.
To prevent possible personal injury carefully follow the steps below.
2. Put Tool (B), except for the 8T5287 Wrench, in position on the fuel pump housing as shown. Lower the handle to center the adjusting screw with the fuel line seat. With the handle down in the locked position, the adjusting screw must just be in contact with fuel line seat (1). If force is needed to lower the handle or there is a gap, remove the tooling, and make an adjustment to the screw.3. Loosen bushing (2) 1/4 of a turn.4. Put Tool (B) in position on the pump housing with the handle down in the locked position as shown.5. Remove bushing (2) from the pump housing.6. Carefully and slowly lift the handle to release the spring force. Remove the tooling. 7. Install Tool (C) on fuel pump (4) as shown.8. Remove seal (3) and fuel pump (4) from the fuel pump housing. 9. Remove spacers (5) from the pump housing. There must be a pump installed on either side of the pump to be removed to install Tool (B). If there is no pump, take a pump already removed, and remove the spring so there will be no spring force, and install it in the pump housing. See Install Fuel Pump. Spacers (5) are the same thickness for each fuel injection pump so they can be mixed. The fuel injection pump plungers and barrels are sets and cannot be mixed.Install Fuel Injection Pumps
1. Install spacers (5) in the fuel pump housing.2. Move the rack until Tool (A) can be installed to hold the rack in the center position. The rack must be in the center position to install the fuel injection pumps.3. Install a fuel pump without its spring so that Tool (B) can be installed. See Step 5 for correct fuel pump installation. 4. Install Tool (C) on the bonnet of the fuel pump as shown.5. Install the fuel pump in the pump housing with the saw cut (slot) (9) in the gear in alignment with small pin (6) in the lifter assembly and groove (8) in the barrel in alignment with large pin (7) in the pump housing. 6. Install the seal and bushing (2) on the fuel pump.7. Put Tool (B) in position on the fuel pump housing as shown.8. Lower the handle slowly and carefully. If the fuel pump is not installed correctly, the handle will not go all the way down. Do not try to use force on it. Remove and install the tooling and the fuel pump again.9. Make sure the seal is in its correct position, and start to tighten bushing (2). Remove the tooling, and tighten the bushing to a torque of 260 15 N m (190
