applications, the flywheel, clutch, and pressure plate is also a balanced assembly. During the powertrain build
process, balance weights may be added to the crankshaft balancer and/or flywheel as required.
In order to maintain engine/clutch assembly balance, it may be necessary to install or remove balance weights
as detailed below:
Crankshaft Balancer
z
Existing balancer onto existing engine:
The balancer position must be marked prior to removal and installed to the original position. Refer to

CYLINDER LEAKAGE TEST
IMPORTANT: The flywheel, clutch, and pressure plate are a balanced assembly and are not
available as individual components. The pressure plate mounts or locates onto
the flywheel via two dowel pins in the flywheel. If the pressure plate is not
aligned properly onto the dowel pins and tightened down, the pins may bend
and the plate may be incorrectly positioned which will effect component
balance. Refer to Clutch Assembly Replacement .
