Install cap (10) with the fasteners that were used to secure cap (8). Use 4C-5598 High Temperature Anti-Seize on the threads. Torque the fasteners to 7 1 N m (62 9 lb in).
Install switches (9) .Note: Do not apply an excessive amount of anti-seize compound. Anti-seize compound in the switch can cause the switch to fail.Use 4C-5598 High Temperature Anti-Seize on the threads. Torque the switches to 16 3 N m (142 27 lb in).
Connect switches (9) to the engine wiring harness.
Install clips (11) with bolts (11) .Torque bolts (12) to 47 9 N m (35 7 lb ft).
Use 9X-6772 Cable Straps to secure the wiring harness to clips (11) .Note: Ensure that the vent holes on the limit switch assembly are covered if the air shutoff valve is repainted. This will prevent paint from entering the switches. Ensure that the vent holes are free of debris after the air shutoff valve is repainted.

Typical example (13) Harness for the solenoid (14) Harness for the new limit switch
Secure harness (14) for the new limit switch onto harness (13) for the solenoid. Ensure that the wiring harness is not touching the exhaust manifold or the shielding for the exhaust manifold.
Perform the operational test.Operational Test
Before putting the engine back into service, perform the following operational test on the air shutoff system. This test will verify that the system is functioning properly.
Verify that the gates for both air shutoff valves are in the open position and that both of the limit switches are connected.
Turn the power for the engine control panel to the ON position. Both of the gates for the air shutoff valves should remain open. If the gates did not remain open, check the wiring for the limit switches.
Repeat Step 2 until both of the gates remain open.
Verify that the power for the engine control panel is in the ON position.
Activate the emergency stop button.Both of the gates for the air shutoff valves should close. If both gates did not close, check the wiring for the limit switches and the wiring for the solenoid.
Repeat Step 5 until both of the gates close when the emergency stop button is activated.
Turn the power for the engine control panel to the OFF position.
Reset the emergency
