My adaptor plate and hub arrived. In 1978, Porsche switched the design of the flywheel from a 6 bolt to a 9 bolt design. The supplier had yet to encounter a order for a 9 bolt version, so I sent them my flywheel so they could measure the proper dimensions for the hub. The adaptor plate connects the bodies of the transmission and electric motor. The hub connects the rotating shaft of the electric motor to input shaft of the transmission.
Now that I have the flywheel back, I took it to an automotive machinist to have it resurfaced and balanced. The machinist was an interesting man. He works on Cosworth racing engines and he restores T-28 Trojan aircraft – a US military plane used to train Air Force and Navy pilots in the 1950’s. The shop was located in an aircraft hanger, and it was packed with machine tools, engine blocks, and several aircraft in various states of restoration.

I felt the same way about my HPEVS AC-50.
