Back in 1978 while working for the County Road Dept. , one of my jobs was to take the old CAT D-8 Cable Dozer around to all of the Communities in the County and cut new Garbage Pits and backfill the old ones. The old D-8 was started by a hand-cranked Pony Motor, and the hand crank came out of the Hood at the rear of the Diesel engine. This hand crank was unlike anything that I had ever used before. I was familiar with hand cranking old tractors but those cranks were always horizontal; this crank on the Dozer was VERTICLE. Under the Dozers Hood there was a spring on the shaft of the hand crank that kept the crank elevated off of the cranking cam on the Pony Motor. In order to start the Pony Motor you had to push down on the crank while cranking the crank handle, which necessitated that you have a good grip on the crank handle and not 'open palmed' like starting a tractor.
Well, I arrived at my first job site and went to fire up the Dozer so that I could unload it from the low-boy trailer. I grabbed the crank handle, pushed it down to engage it with the cam on the Pony Motor, and gave it a crank - BIG MISTAKE !!! The Pony Motor kicked back and dislocated my left thumb ( sure glad I was using my Left hand, as I'm Right Hand dominant ) . I reduced the dislocation ( I've been medically trained in how to properly reduce dislocations ) . I rummaged around in the garbage pit and found an old metal lid from a coffee can, which I then cut a hole in the center of it and slipped it down on the handle of the crank. I was then able to 'open palm' the crank handle while still maintaining a downward pressure. - This solved the problem and I didn't have any more problems with the crank handle.
When I finally got back to the Shop that day, I notified the Road Dept. Superintendant as to what had happened and what I had done to correct the situation. I filled out an Accident / Incident Report, and stated on it the remedy. The next day we cut out a disc of 1/8" steel plate, drilled a hole in the center, and permanently welded it onto the hand crank handle.

Today's Featured Article - The Fordson F Ignition System - by Anthony West. A fellow restorer contacted me earlier this year asking for some help and advice on a model F that he was restoring. He had over a period of months spent a fair amount of his hard earned cash on replacement parts for the old "trembler" ignition. Sadly though all his efforts seemed to be a waste of time and money as he still couldn''t get the temperamental old thing to run correctly!! If i said that this was a little frustrating for him that would be "conservative" in fact the problem had reduce
