The journals for the Hercules Diesel truck engine are being precision measured.
Much hand polishing during the inspection process to reveal any defects, I did the same thing with the Cadillac cam shafts while working in Bay City Powertrain. The previous link shows assembled cams which I also worked on overtime.
Looks like the crank is almost ready for packing. Buick also cast the engine blocks for this engine.
Heat treating on the Hercules crank.
