For these applications the cover assembly is bolted to the crankshaft and then the flywheel is bolted to the cover assembly. The flywheel is "timed" to the cover by two roll pins. If the cover and flywheel are not oriented to each other during bolt up, one of the roll pins will not line up with the hole or notch in the cover stamping. This results in a deformed cover stamping and the clutch will not release. Prior to installing the flywheel, check the orientation of the pins and mark the flywheel to line up correctly.
