(Universal) For Clutch-Hub: 15-28 mm.

As a result of newly-developed parallel expansion technique it it now possible to align the clutch plate to the pilot bearing in the crankshaft flywheel.
Clutch assemblies no longer equipped with a pilot bearing in the crankshaft can be aligned with the cover plate using the new parallel expansion technique.

Advantage:

The expanding segments expand in the same axis if both the tool body and the crankshaft, so that aligment of the clutch plate is possible relative to either flywheel or cover plate.
