The early 3208s were not the best engine Cat ever designed, IMHO, however there are TONS of them out there in alot of different HP and applications. I was not impressed though.

The good news is my seat cutoff switch works -- the engine stopped quickly as I flew off the seat...
The bad news is, after putting the tractor on its feet again, I made the mistake of trying to crank it over. (this was before I posted this question) It didn't crank -- well, it tried to, then wouldn't turn. A good indication that there was oil in the cylinders.
Then it sat for a couple days. Then I tried to start it, and it started up. I don't notice anything bad happening now when it's running. Would I notice a bent rod, or any other bad things that could have happened when I originally was trying to crank it over?
To answer the question on what NOT to do: When using a FEL, with a lot of weight in the scoop, be VERY careful on slopes. I will not be going anywhere near a slope with the scoop loaded any more...

I'd guess the fuel may have drained down and you had an air block. It may have started if you'd bled the lines.
As far as a rod...you should hear a loud knock with a bent rod...
So, how did the tractor run? Was it OK on power?

I have very little diesel diagnosis experience, my career was all gas, but just from basics it would seem that you would notice something if it had a bent rod or busted ring/piston - a miss or vibration and in the case of ring damage, some smoke. A bent rod would decrease compression in it's cylinder and possibly not even ignite the fuel mix if it were bent enough. Does your engine seem any different?
Amen on the FEL - many times that I've had repetitious loader work to do, I've had to dump the bucket a little prematurely when the rear wheels left the ground going down a grade - luckily I always do this in a straight line, if the front wheels had been turned the tractor could have gone over very easily. Everyone knows that you should keep your bucket low for transport but you gotta keep it up high enough so the materials don't fall out of that full bucket you tried so hard to fill fully !!

As Skipmarcy suggested if you can't feel a difference in how it runs that is a good sign. I'm not a mechanic by trade but I unfortunately have some experience in bent rods. If a rod were bent then the piston will not travel as high in the cylinder as it used to. You should be able to detect this with a compression test. A good reading will give you some peace of mind. If there is some compression variance between cylinders it does not mean bent rod for certain. It could be due to normal wear.jwk said:

I think the good news is, that if you got thrown off the tractor you were not hurt, or worse. One can always rebuild an engine. I think others have given good info on here as to the bent rod. If your engine is running all right your more than likely good to go.
At any rate if you have a tractor dealer nearby he might check the compression and he might have an exhaust pyrometer if there is a difference in the temps on the exhaust runners then you may have a weak cylinder. But that could be from normal wear as well.
If it were me and it runs as well as it did, I wouldn't worry about it.

I have had a little experience with a bent rod from the engine being hydrolocked. As was mentioned, a compression test will show if that's the case but I think chances are that it would be obvious without it. In my case the increase if fuel smoke was so obvious it couldn't be ignored and I suspect you would be seeing that too if one bent.
