[AT] "diesel" engines running backward

[Dan Folske]

The 4-53 GM diesel in my Oliver 1950 has an emergency shutdown "flapper" to
prevent damage if the engine begins to run backwards. These are 2-stoke
engines which will suck the oil out of the crankcase and burn it as fuel
until they disentegrate if running backwards. One of the first things I did
when I got the tractor was replace the cable which operates the shutdown
flapper. Probably never have to use it, but at least now I can if necessary.
