system originates from the engine. The engine, an eight cylinder V four
cycle, is liquid cooled. The electrical system is a 24 volt negative

camshaft driven oil pump. Engine power is transferred from the engine
flywheel to the torque converter.

the drive train through a hydraulically activated clutch.
Shafts A and B have universals attached on both ends. Shaft B has one
universal on the end that goes to the front differential. On the end
