Illustration 2 g02173966
(4) Gaskets (5) Studs
Remove gaskets (4).
Install new gaskets (4) .
Apply 4C-5597 Anti-Seize Compound to the threads of studs (5).
Install the ARD combustion head. Refer to the Disassembly and Assembly Manual, "Combustion Head Group (ARD) – Remove and Install (Clean Emissions Module)".
Apply 4C-5597 Anti-Seize Compound to nuts (6). Tighten the nuts in a crisscross pattern to a torque of 23 3 N m (17 2 lb ft). Tighten nuts (6) again in a crisscross pattern to a torque of 28 3 N m (21 2 lb ft).

Typical example (8) Pilot fuel fitting (9) Main fuel fitting (10) Coolant ports
Install the ARD coolant lines in the coolant ports (10). Tighten the lines to a torque of 12 1 N m (9 1 lb ft).
Illustration 5 g02173895
(11) 361-4646 Check Valve As (12) 361-4651 Check Valve As
Remove the current adapter (11) from the ARD head assembly and install the new adapter (12) Tighten the adapter to a torque of 28 3 N m (21 2 lb ft).
Install the ARD pilot fuel line onto pilot fuel fitting (8). Tighten the line to a torque of 20 N m (15 lb ft).
Install the ARD main fuel line onto main fuel fitting (9). Tighten the line to a torque of 13 N m (10 lb ft).
If a visual inspection of the fuel line connections and the coolant line connections is not performed during the ARD ignition test, fuel leaks or coolant leaks may result in a fire hazard which could result in personal injury or death. Visual inspection of the fuel line connections and the coolant line connections is the only method to detect a fuel leak or a coolant leak on the ARD system. Visually inspect the fuel line connections and the coolant line connections at the ARD head and the ARD manifold when the ARD ignition test is active.

Perform a test for ARD ignition. Refer to Troubleshooting, "ARD Ignition - Test". Refer to Illustration 6.Note: The "ARD Ignition - Test" can be successful even if a fuel leak is present. The ARD ignition test pressurizes the main fuel line and pilot fuel line with pressure in order to help assist with detecting a leak. Visually inspect all fuel line connections for a leak during the test for the ARD ignition. Visual inspection is the only method in order to detect a fuel leak on the ARD system.Note: Also, check the fuel connections at the ARD fuel manifold and the connections for the coolant at the ARD combustion head for any possible leaks.
