Test Equipment (1) 8T-0853 Pressure Indicator (2) 3B-7734 Pipe Nipple (3) 3B-6483 Cap (4) Oil Supply Line (5) 3B-7263 Pipe Nipple (6) 3B-9389 Shutoff Cock Fitting (7) 3B-9389 Shutoff Cock Fitting (8) 1F-9369 Service Tee (9) 5K-3772 Hose Assemblies (10) 004-4914 Tee
Remove the cover of the contactor switch and disconnect the wires from the normally closed (B or Blue) terminal.
Disconnect the oil supply line from the contactor switch and install the test equipment, as shown.
Connect the 5K-3772 Hose (9) from tee (10) to the contactor switch. Put the end of the other 5K-3772 Hose (9) in a pan.
Connect the 8T-0500 Circuit Tester between the common terminal and the normally closed terminal. The light of the circuit tester will be activated.
Close 3B-9389 Shutoff Cock Fitting (7) and open the other 3B-9389 Shutoff Cock Fitting (6) .
Look at the pressure indicator, start the engine and run it at low idle rpm. The light must go out, with an increase in oil pressure, at the specification of the switch.
Close 3B-9389 Shutoff Cock Fitting (6) and slowly open the other 3B-9389 Shutoff Cock Fitting (7). The light must be activated, with a decrease in oil pressure, at the specification of the switch.
Stop the engine.
Connect the wire(s) to the normally closed terminal.
On contactor switches with a button or a control knob either push the button or turn the knob to the OFF position.
Close 3B-9389 Shutoff Cock Fitting (7) and open the other 3B-9389 Shutoff Cock Fitting (6) .
Start the engine and run it at low idle rpm.
Put a jumper wire between the common terminal and the normally closed terminal. This will check the system beyond the contactor switch.
Remove the jumper wire.Adjustment of Micro Switch Type Contactor

Contactor Switch For Oil Pressure (11) Set for start button (12) Adjustment screw (13) Spring (14) Locknut (15) Contact button
Loosen locknut (14) and turn adjustment screw (12) counterclockwise to make a decrease in the tension of spring (13) .
Illustration 3 g00510412
Wiring Connections (D) Normally closed B terminal (E) Normally open W terminal (F) Common R terminal
Disconnect the wires from the normally closed terminal of the switch.
Start the engine and run it at low idle rpm.
Close 3B-9389 Shutoff Cock Fitting (6) and slowly open the other 3B-9389 Shutoff Cock Fitting (7) until the pressure indicator shows the pressure specification at which the switch must close with a decrease in pressure. Close the 3B-9389 Shutoff Cock Fitting (7) .
Ensure the set for start button (13)
