Reply to "clutch shudder"

A slight shutter can be common with a pantera clutch since there is no Marcel spring. The marcel spring, or the flat plate spring between the pads, makes release smoother by more slowly adding friction. The Pantera has little room for cluch travel, so its marcel spring was removed or flattened. This is the same style clutch that is used in race applications.

Sometimes this will improve as the clutch wears in a little and the flywheel and pressure plate are polished.

Of course, the shutter can be caused by hard spots from overheating in the flywheel or by grease on the clutch.

My car shutters a little.
