Use Tooling (B) in order to remove O-ring seals (14) and (15) from the heated nozzle (9). Discard the O-ring seals.Installation Procedure
Install combustion head (6) in the reverse order of removal.
Apply Tooling (A) onto the threads of studs (10). Tighten studs (10) to a torque of 17 2 N m (150 18 lb in).
Apply Tooling (A) onto the threads of the studs and nuts (5). Tighten nuts (5) in a crisscross pattern to a torque of 23 3 N m (204 27 lb in). Tighten nuts (5) again in a crisscross pattern to a torque of 28 3 N m (21 2 lb ft). Tighten nuts (5) again in a crisscross pattern to a torque of 28 3 N m (21 2 lb ft).
Use caution when you are using isopropyl alcohol. Avoid prolonged skin contact with isopropyl alcohol.Vapors may be harmful if inhaled. Use only in a well ventilated area. Do not smoke while using isopropyl alcohol.Isopropyl alcohol is flammable. Do not use near an open flame or near welding operations. Keep isopropyl alcohol away from heated surfaces exceeding 482°C (900°F).
Note: This connection is an electrical connection and cannot be lubricated with a petroleum-based lubricant. Isopropyl alcohol is the only approved lubrication for this connection.
Lubricate new O-ring seals (14) and (15) with Tooling (C) prior to installation.
Apply Tooling (A) to the threads of flame detection temperature sensor (8) and install the sensor. Tighten flame detection temperature sensor (8) to a torque of 45 5 N m (33 3 lb ft).
Tighten spark plug (3) to a torque of 47 4 N m (35 3 lb ft).
Check the coolant level. If necessary, refer to Operation and Maintenance Manual, "Coolant - Change" for the proper filling procedures.
Perform the ARD ignition test. Refer to Troubleshooting Manual, "ARD Ignition - Test".
