The crank shaft makes it home from the shop! The crank is 4 inches in diameter and as you can see just fits cross ways in the back of my Dakota pickup....
I used my Ferguson TO30 tractor and post hole digger arm to lift the crank shaft up and lower it into the main bearings on the engine base...
This photo is a close up of the crank shaft and if you look real good you can see the .875 wide keyway slots on each side...
