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.
