The flywheels have been clocked and have a run out of around 15 thou. Ideally this needs to be less than 5, so the wheels need to be both jacked apart and twisted around the crank pin. Accurately!

Jacking the wheels apart is fairly straightforward, but twisting them around the crank pin is more tricky. The plan is to mount them on the press, then use the press to push them around the crank pin.

The photo shows the CAD model (Cardboard Aided Design 😁😁) for bolting the wheels to the press. Bolts are in place ready for the heavy lift of the crank assembly onto the press.
