I answered an ad in craigslist for an Isuzu C240 diesel engine and bought it for $100, thinking it was a bargain. It is hanging from a tree branch in my back yard. I can turn the crank with the crank pulley and the owner said it was rebuildable but apparently it was removed from the tractor/front loader in a hurry and they dropped the bolts holding things together sacrificing the value they had in their organization. Possibly they needed the front loader to dig someone out of being trapped in a well casing.
