Good Design

The flywheel has four holes for bolts and two larger holes for drive pin. The drive pin holes are too large for the SCAT crankshaft flange pin holes. A custom pin was necessary to achieve a proper tight fit. The technical description of the flywheel can be improved. A six bolt installation would not provide a good fit at drive pin locations.

Center hole will not accomadate the pilo

I ordered this flywheel for a 1950 Mercury and when I received the flywheel I found that the center hole was too big for the pilot bearing and had to return the flywheel.

I have installed a SCAT crankshaft in an 8BA block. The drive flange has two holes for 7/16" drive pins. The corresponding holes in this flywheel are just under 1/2" (0.4935"). The resulting loose fit defeats the purpose of the drive pins. What is the best solution to this problem?

Clutch Pressure Plate #91015637 requires 6 taped holes on an 11 5/8" bolt circle. Flywheel #91015629 does not appear to have the required bolt holes. Does the fly wheel require drilling and taping the required holes?
