TM 9-2815-220-24 SMOKE GENERATOR WIRING HARNESSES (2DR) REPLACEMENT (PN 12354467, 11672386) 0068 00 THIS WORK PACKAGE COVERS: WP 0068 00-1 Removal, Cleaning, Inspection, Repair, and Installation INITIAL SETUP: Tools: General mechanic’s tool kit (item 121, WP 0176) Mandatory Replacement Parts: Lock washer (as needed) (item 92, WP 0175) Lock washer (1) (item 93, WP 0175) Tie wrap (as needed) (item 80, WP 0175) Tie wrap (1) (item 81, WP 0175) Personnel Required: Track Vehicle Repairer (1) 63H10 Equipment Conditions: Engine removed from vehicle and placed on a flat stationary surface REMOVAL CAUTION There are two configurations of the smoke generating system. Early systems use a dual solenoid configuration. Newer/improved systems use a single solenoid system. The newer system removes the two flywheel end mounted solenoids and replaces them with a single solenoid at the damper end of the engine where it is cooler. It was found that fuel, trapped between the two solenoids and heated by the close proximity of the exhaust, expanded and caused internal seals of the solenoids to fail resulting in un-commanded smoke generation and higher fuel consumption. ECR CO-M6185 authorizes the change. NOTE This work package covers the maintenance of the smoke generation wiring harness for the 2DR engine model with single or double fuel solenoid configuration. If you have a dual fuel solenoid configuration requiring repair, it is recommended that you reference ECR CO-M6185 and convert your smoke generation system to the single solenoid configuration.
