Contactor Switch For Water Temperature
Fabricated heat sink.2F7112 Thermometer.3J5389 Plug.8S4627 Circuit Tester.First Method of Checking
1. Make a heat sink as shown. Material can be brass, steel or cast iron. Drill a 23/32 in. hole through the plate and use a tap to make 1/2 in. NPT threads.2. Put marks on wire connections to contactor terminals and disconnect wire.

TEST OF CONTACTOR SWITCH
1. 2F7112 Thermometer. 2. Fabricated heat sink.3. Remove the contactor and install a 3J5389 Plug. Install the contactor switch in the heat sink.4. Connect the wires to the contactor switch to check all of the system; contactor switch, wires, etc. If the wires can not be disconnected, use the second method of testing.5. When the contactor switch is connected again, start the engine and run it at low idle rpm. The pressure switch will complete the circuit when the engine is running. When applying heat to the water in Step 6, be sure to stir (keep water moving) while heating.6. Put the heat sink and contactor element in water. Use blocks to support the heat sink at surface level. Use a torch to make the water hot and read the temperature on thermometer (1) at which the engine stops (switch is closed). For the 5L6435 Contactor, the temperature should be 209 1 ° F (98 0.6 ° C). Let the water temperature go down. The contactor switch will open when the temperature is 12 ° F (8 ° C) lower than the temperature at which the contactor closes.7. Install new contactor switch if necessary.To check other components in the system, put a jumper wire between C and NO terminals of the contactor switch for water temperature.Second Method of Checking
1. Remove the wires from the contactor switch.2. Connect the 8S4627 Circuit Tester between the C and NO terminals.3. Start the engine and get it hot by making a reduction in coolant flow or air flow through the radiator. Temperature must not go more than approximately 3 ° above the maximum.
If the engine can not be run safely at these high temperatures, the contactor must be checked off the engine.
4. Look at the circuit tester to see when the contactor switch closes. The light will be activated. The temperature must be 209 1 ° F (98 0.6 ° C) for the standard sea level contactor.5. Let the engine run to slow cooling and then stop the engine.6. Install new contactor switch if needed and connect wires to the contactor switch.Electrical Gauges And Sending Units
Source for hydraulic pressure.5P6225 Hydraulic Test Box.Ohmmeter.2F7112 Thermometer.Heat sink. See contactor switch for water temperature.Remember that the electrical gauges and sending units are to operate in electrical balance. For this reason, the voltage and resistance ratings are important to get the correct indications on the gauges.Sending Units for Oil Pressure
SENDING UNIT FOR OIL PRESSURE
1. Terminal. 2. Fitting.The sending unit for engine oil pressure can be checked for resistance to find if it is operating correctly. Connect the sending unit to a pressure source that can be measured with accuracy. Connect the ohmmeter between fitting (2) and terminal (1). Take resistance readings at the pressures shown.If the test performance is correct for the sending unit for the oil pressure, install a new gauge.Sending Unit for Water Temperature
A resistance check can be made to find if the sending unit is operating correctly. Connect an ohmmeter between nut (2) and terminal (1). Put bulb (3) in a pan of water. Use a torch to make the water hot. Put a thermometer in the water to measure the temperature. Take resistance readings at the temperature shown.Refer to CONTACTOR SWITCH FOR WATER TEMPERATURE for heat sink and heat bath use.
SENDING UNIT FOR WATER TEMPERATURE
1. Terminal. 2. Nut. 3. Bulb.If the test performance is correct for the sending unit for the water temperature, install a new gauge.Electrical Gauges
To check the gauge, use the voltage shown as the test voltage. Install a resistance of the value shown, into the supply from the voltage source and connect the ground to the frame of the gauge. The indicator of the gauge should point to the temperature or pressure value given in the chart. The test must be made when the gauge is installed at the angle of 30° back from vertical position.

Clutch Adjustment
CLUTCH ADJUSTMENT
1. Lock pin (push-type). 2. Lock pin (pull-type).1. Disconnect linkage (if so equipped) from the clutch lever. Fasten a spring scale to the clutch lever at the distance, from the lever shaft center, shown in the chart.2. Look at the spring scale. Keep the angle between the scale and the lever at 90°. Pull the lever with the spring scale until the clutch engages. Make reference to the chart to find the correct amount of pull for the clutch assembly. 3. If the pull needed to engage the clutch is not correct, make an adjustment as follows:4. Remove the inspection plate from the clutch housing.5. Turn the clutch until lock pin (1 or 2) can be seen.6.
