1. Crankcases apart
The interior of the crankcases are corroded beyond repair. The walls of the flywheel chamber are paper-thin and nearly breached into the gearbox in a number of places. The gearbox has, however, remained intact and oily and largely free of moisture. Almost everything in the gearbox can be reused. A search on ebay found a cheap set of matching crankcases and these have been ordered.
