Personnel Required:
Track Vehicle Repairer (1) 63H10
Equipment Conditions:
Engine removed from vehicle and placed on a
flat stationary surface
CAUTION
There are two configurations of the smoke generating system.
Early
systems use a dual solenoid configuration.
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.
If you have a dual fuel solenoid configuration requiring repair, it is
recommended that you reference Engineering Release Record (ERR)
CO-M6185 and convert your smoke generation system to the single
solenoid configuration.
ERR CO-M6185 authorizes the change.
Newer, improved systems use a single solenoid system.
The newer
system removes the two flywheel-end mounted solenoids and
incorporates a single solenoid at the damper end of the engine where
it is cooler.
NOTE
This work package includes maintenance of the smoke generation
wiring harness for the 2CA and 2DA models with single or dual fuel
solenoid configuration.
