Looking at the Muskateer there is the old spring assist driven clutch on the input shaft. Seized solid, I am assuming one should be able to move the sheaves and compress the spring on the backside a bit, but she's locked up tight.

Best way to remove these? More familiar with Ford engines and using a bolt-on puller or the FomoCo style power steering puller/installer tools for harmonic balancers/pulleys... but this one does not seem to have any place to get a grip to pull it off the shaft.
