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).

Power Plug To Chassis Harness
Connect 777-PU wire to 777-PU wire on chassis harness.Starter Connections
The connector with the plug in Loc. 3, connects to the bottom starter. The connector without the plug in Loc. 3, goes to the top starter.Air Conditioner (Attachment).
8C9677 Harness Assembly1. Install 8C9677 Harness Assembly to the air conditioner (513-OR and 200-BK).2. Remove plug housing from the EUI engine harness and connect the 2 pin sure seal breakout to 8C9677 Air Conditioner Harness Assembly.Steering Flow Switch.
Connect the 2 pin sure seal breakout to the steering flow switch.Ether System
* Trucks equipped with auto ether system with Multi-Point Oil Pressure Sensing perform the following steps:
8X5415 Wire AssemblyRemove the code plug installed in the chassis auto ether harness on top of the left fore-aft beam near the cab and replace it with 8X5415 Wire Assembly. This disables the multi-point oil pressure function.Remove the engine oil pressure sensor control and its hardware on the right rear of the engine. It will be replaced by the oil pressure sensor for the EUI system.* Trucks with auto ether system where the ether coolant sensor is located in the water regulator housing on the left side of the engine perform the following steps: If the truck has the ether coolant sensor in location (A), the new EUI cover (7E5326) must be reworkedThe bottom right port (B) must be changed to No. 6 Port. Drill and tape for (9/16-18-2B threads).Move the ether coolant sensor to location (B), new No. Port 6. Relocate the connector clip to the lower right bolt of the cover if necessary to retain connection.Tachograph Group
8X8529 Tachometer Group (1) 4N3695 Cable Assembly. (2) Two 338248 Clips. (3) 5M3062 Bolt. (4) 8T4896 Washer.1. Install the 8X8529 Tachometer Drive Group as shown in the illustration above.Tighten the tach cable to 11.3 1.8 N m (100.0 15.9 lb in) at the engine end and 5.7 0.9 N m (50.4 8.0 lb in) at the cab end.2. This completes the EUI retro-fit installation.3. Clean and paint all welded areas.4. Secure all harnesses and wires with tie wraps.5. Check all areas that were modified or changed.6. Connect the batteries.Description Of New Lamps And Switches On New Dash Plate
* CHECK ENGINE LAMP (1)This lamp is used to indicate when a problem exists in the engines electronic control systemThe indicator will come on when the start switch is in the ON position and the engine is not operating. The lamp will stay on approximately 5 seconds, then go out.This lamp is also used to read diagnostic flash codes in conjunction with the diagnostic enable switch.* AIR FILTER RESTRICTION LAMP (2)This lamp indicates that the engine air intake filters are plugged.If the indicator comes on, service the filters that day.* ENGINE OVERSPEED LAMP (3)This lamp indicates the engine rpm is too high. The engine overspeed alarm will sound also when the engine is exceeding maximum allowable limit for safe operation. The lamp and alarm will remain ON as long as the engine is overspeeding.* THROTTLE
