DESCRIPTION
The 2.5L Common Rail Diesel engine is equipped
with two nodular cast iron balance shafts in a cast
aluminum carrier. The balance shaft assembly is
mounted to the engine block (Fig. 88).
OPERATION
The balance shaft is driven by the crankshaft. The
balance shafts are connected by heelical gears. The
dual-counter rotating shafts decrease second order
vertical shaking forces caused by component move-
ment.
