b. Fuel Shut-off Solenoid Disassembly
DO NOT disassemble a fuel shut-off solenoid. Replace a
defective fuel shut-off solenoid with a new one.
c. Fuel Shut-off Solenoid Inspection and
Replacement
Use a 12-volt DC source and ground to test the solenoid.
Energize the solenoid, and watch for the plunger to
retract. If the plunger does not retract, replace the fuel
shut-off solenoid with a new one.
d. Fuel Shut-off Solenoid Installation
1. Clean the exterior of the fuel injector pump.
2. Using the hardware removed earlier, install the nut
holding the linkage to the arm on the fuel injection pump.
Install the two bolts to secure the solenoid to the
mounting plate.
3. Connect the wiring connector at the fuel shut-off
solenoid lead (Fig. 9 -86, 2).
4. Connect the negative (–) battery cable to the
negative battery terminal (Fig. 9-87, 1).
Figure 9-87 Battery Cable Connections
5. Clear personnel and any obstructions from the area
around the vehicle.
6. Start the engine. If the engine starts, the fuel shut-off
solenoid is functioning. If the engine fails to start, the
fuel shut-off run solenoid may have a poor ground
connection. Visually check the wiring at the fuel shut-
off solenoid leads and/or check for continuity with a
voltmeter as required.
7. Check for fuel and/or oil leakage around the solenoid.
9.15.3 Hydraulic Oil Temperature Switch
The hydraulic oil temperature switch (Fig. 9-88, 1) is
threaded into a fitting (2) at the lower inside wall of the
hydraulic oil tank.
Figure 9-88 Hydraulic Tank Oil Temperature Switch
The hydraulic tank oil temperature switch connector
(Fig. 9-88, 3) attaches to the wiring harness and
operator’s instrument cluster. When the hydraulic oil
temperature is above 195° F (91° C), the hydraulic oil
temperature warning indicator on the operator’s
instrument cluster illuminates. The vehicle should be
stopped and the engine allowed to run at high idle for five
minutes.
If the warning indicator continues to illuminate after five
minutes, the engine must be shut down to help avoid
damage to the hydraulic system.
