Installation Installation 1. Install a new O-ring onto sensor (4, Figure 20-11) and install sensor onto adapter (3). Tighten the sensor to 22–29 ft.lbs. (30–39 N.m) torque . 1. Install inclinometer (3, Figure 20-13) with cap- screws, nuts and lockwashers (4). 2. Install a new O-ring onto adapter (3) and install complete adapter/sensor assembly onto valve (2). Hold the valve body and tighten adapter/sen- sor assembly to 103 ft.lbs. (176 N.m) torque . 3. Connect the sensor wiring to the truck wiring harness. The sensors have three wires. Be sure that wires are connected correctly. (Figure 20-12) FIGURE 20-12. SENSOR SIDE CONNECTOR VIEW FIGURE 20-13. INCLINOMETER 1. Operator’s Center 3.

INCLINOMETER As the truck is tilted fore or aft, the weight distribution between the front and rear axles changes. To compen- sate for this, the inclinometer measures the ground angle at which the truck rests. This data is then sent to the payload meter so it can calculate the correct payload weight. The inclinometer is located below the operator’s center console (passenger seat structure). FIGURE 20-14. INCLINOMETER SIDE CONNECTOR VIEW Removal 1. Disconnect inclinometer wire lead from harness. 2.
Remove the three capscrews, nuts and lockwash- ers (4, Figure 20-13) and inclinometer (3). Adjustment 1. Park the truck on a 0% grade. 2. Loosen the three inclinometer mounting cap- screws (4, Figure 20-13) and rotate the inclinome- ter until a voltage range of 2.6 ± 0.1 volts can be measured (using a volt-meter) at pins 1 and 2 of the inclinometer electrical harness connector. 3. Tighten all capscrews (4, Figure 20-13) to stand- ard torque, after the adjustment.
