fliiped tractor

[Diggin It]

However, be VERY CAREFUL when rotating the engine by hand, some will start up once conditions are correct for running.

Disconnecting the battery should prevent that, right?

I tried to start with key, I can hear fuel pump running, lights are on, and battery has 12v but engine won't turn over at all, or even click? Does this sound like hydro lock? If so, do I need to pull gas tank to get to head cover and remove glow plugs? And do I need to replace head gasket when installing back? Also, do I need to remove radiator and/or fan to turn by hand? I am hoping there is an easier solution.

Make sure you understand exactly why things went wrong with this flip - Lady Luck was with you on this one, but don't count on her next time.... a quick trip to the Safety forum will show fatalities listed.

If you know roughly where the engine oil was on the dipstick before rolling, how does it compare now ? If you are not mechanically inclined, don't pull the head off yourself would be my recommendation.

Check the electrolyte level in the battery - if enough has drained out, a meter may show 12 volts with no load on the battery, but there may not be enough capacity to spin the starter.

When you turn the key to Start (may need 2 people to test) does the starter actually get 12volts on it's main terminal ? Use a meter or 12volt test light. (Relay or wiring may have jostled loose).

Is the tractor in neutral? Are you pushing the clutch in while cranking? The tractor might also have a rollover switch that needs resetting before you can turn it over. You'd need to call the dealer on that one unless someone can chime in and say.

You should be able to turn the engine over with the fan belt. Either put a wrench on the alternator pulley or turn it with the fan blades. You might also need to hold the belt tighter on the slack side with your fingers. Please do this with the key out of the ignition.

If you crank don't hold the key steady in the start position. Just lightly bump the starter a few times till you know that the engine is going to turn over without any internal obstructions.

I get the impression that you didn't take anything apart before your try. Best plan would be to bump the starter for a few revolutions . Hopefully the crank wouldn't power through any obstruction.
For me Priority 1 would be to check out the battery. Has it leaked acid on stuff? Is it dead?
I would check the fluids for level, look and smell.
Several folks mentioned to have the key off before sticking your hands in place's. Good call but understand that a diesel can still fire without the key on.
I would inspect the air cleaner for oil and fuel saturation. Don't know if your rig has a wide open or restricted air intake so I would have a large rag handy to suffocate the air intake on a runaway.

UPDATE: pto was engaged is reason it did not turn over. I started with key and a puff of black smoke came out and it ran fine. I ran for awhile before reading replies. Should I change oil to be safe? thanks for all the help. I'll have to tell my wife about the serious accident quote, that's a good one.

Gotta be really careful with all engines.... that said, diesels have elevated risk.

If you are going to turn a diesel over by hand, do it S L O W L Y.... using the other precautions stated.

(I get that diesels aren't easy to turn over , but somebody reading this may have arms like stove-pipes....)

Congratulations.

An accident like that presents more learning potential than many classes I've taken.

We all start one cylinder gasoline engines all the time without batteries which is why we have to pull the plug wire during testing. But I'm not sure if one person can spin a diesel fast enough to get to that point of self starting. Or if it can be done without things like fuel pumps and injectors getting power from a battery. I still have to learn diesels from scratch if I end up buying one.

With no water immersion described, plenty of folk would just put that tractor back to work.

I'd sleep better with the oil changed (and filter), but I'm pickier than many....

DO - check ALL fluid levels now though, including the battery.

Check the fluids and clean your seat and it will be fine. I would go around and shake everything to make sure that no brackets or bolts were knocked loose.
