You don't need to freeze the crank. Just put the bearings in a toaster oven set at 400 degrees for around 5-10 minutes. They will slip right on the crank.

The bearings on the primary drive should be carefully inspected and evaluated for replacement. When I rebuild a Puch motor, I replace all the bearings. There is also an oil seal on the primary drive that should also be replaced.
