First Rollover!!

[RonR]

So if an engine laying on it's side lets oil run into the cylinders, wouldn't letting it sit for an equal amount of time on it's feet let it run back out?

I've never messed with injectors, and don't really want to. I'd think if mine did that, and laid on it's side for 4 hours, I'd let it sit for 8 hrs and then try it.

Is my logic flawed??????????????

THKS.

Instead of pulling the injectors, how about pulling the glow plugs? Seems like that would be simpler...and more easily done by a novice like me anyway.

Personally I would not assume that if the oil leaks in when the tractor is on its side that it would leak back out of the cylinders when the tractor is righted. The piston rings might pass oil in the abnormal direction, and hold it in otherwise, sort of like a check valve...

To carry the thougt a step farther, when the tractor is righted, how does one verify whether oil is in there or not? Crank the engine with the injectors (or glow plugs) out, and watch for oil spray?

If I had a choice, I would take the glow plugs out myself if it were a usable solution. Just seems more fool (or should I say Henro) proof... /forums/images/graemlins/blush.gif /forums/images/graemlins/grin.gif

Good Point Henro. I was going to pull the plugs anyway to check them. By cranking with the plugs out do I achieve the same effect that I would by pulling the injectors (releasing the pressure in the cylinder)?

Any ideas on this would be GREATLY appreciated!! /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif

Looks like it will handle the situation well. Just remember to bring along some padding to protect the machine from the chain that is going to bring it back on its "feet". How are you going to get it to where you are going to service it? I suggest that you consider having some old tires along with you in the event that it needs to be pushed somewhere. That blade looks like it can do a lot of damage without even trying. See if he can push the loader closed while you hold the valve before it is uprighted. That will minimize the possibility of damage to the arms in the uprighting process.

MFL, Others have said it here, but I'll repeat anyway. Thanks for posting. So many times I have started to do something with the tractor, only to have a tiny thought bubble form in my head about something I read here. Then I change my technique or think more carefully about what I was going to do or how I was going to do it. It's one of the reasons I try to read all the reports of "bad tractor afternoons".

Glad you weren't hurt and hope your tractor comes out ahead. Thanks again for helping us all be a little safer...

 

[Junkman]

You refer to "plugs" ..... Am I correct that this is a diesel engine? Henro is correct, removing the glow plugs will accomplish the same thing. As long as the cylinders are vented is all that is needed. If there is any oil in the cylinders it will be pushed out. There will be some residual oil that will not be expelled, but upon starting it will burn off. There won't be a mosquito for miles after the first 30 seconds of running. Just let it idle for 15 minutes or so and all should be well.

while it is on it's side it would be a great time to servive the underside /forums/images/graemlins/shocked.gif /forums/images/graemlins/cool.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

Can you put a socket on the harmonic balancer bolt and rotate the engine without having to remove anything? A complete rotation or two that way will will let you know if theres anything in the cylinders to hydro lock the engine. If it doesn't rotate freely then pull the glow plugs or injectors and try again.

Very glad your ok. Venting the cylinders are important. Rotating the engine with trapped oil / fuel is called hydraulicing and will cause bent connecting rods and bearing damage, sometimes worse. Beautiful tractor, hate to see anything happen like that.

Thanks for sharing and taking the time to post the photos.

I'm always amazed at how much I learn by reading these posts and the common sense that is expressed that I don't seem to have.

There's been some great advice given, thats for sure!!!!!!!!!

Before you turn the engine over with the glow plugs out, figure out how the fuel stop solenoid is wired. Is it normally closed and it takes power to open and run. You don't want to be injecting fuel as you are trying to get stray oil out. I believe that Kubota engines are indirect injection like my GMC diesel pickup so that there is a small auxillary chamber where the injectors and glow plug are. If you get a large amount of spray out, you might want to bring each piston to the top and suction out what oil you can.

I don't know if your tractor has a compression release, but, if so, After getting upright, I would engage it and try turning engine over with a breaker bar and socket. In either case, I would try the breaker bar and socket. That should blow any oil out the valves or squeeze it past rings depending on what stroke a cylinder is on. No need to remove injectors or glowplugs, unless it won't turn over with the breaker bar.

 

[BGL990]

This may be a dumb thought, but personally I would be a little bit leery of turning a diesel over by hand with a breaker bar without venting the cylinders if I thought there was oil in them. Not for fear of breaking connecting rods, but for fear of it firing. A diesel will run on engine oil and if the rings are sealing well enough to hold compression when turning over slowly I wonder if you could actually generate enough compression heat to start the engine? (this would be a Bad Thing while you are hanging on to the breaker bar ...)

As I said, probably a dumb thought, but if you have the option of removing glow plugs or injectors, why take the chance?

 

[Wildman1]

Same darned thing almost happened to me a few weeks ago. I was subsoiling and picked up a half bucket of dirt on a slight side slope. Bucket was waist high as I backed up with it. Then the right rear tire rolled up over a large rock and she started to go. I poked the front go pedal and dropped the bucket and she settled down.

I'll NEVER pick up a load in the bucket without the proper ballast on the rear...EVER!

 

[DannyD]

Would there not have to some sort of ignition for this to happen. Asking, not commenting. I would think if the battery cable was taken off (which should be anyway) that there would be no chance of that, and not having the ignition on might be enough to not let this happen.

If it were my tractor and under some kind of warranty, it would be in the dealer shop. Insurance may even take care of the repairs if you were on your own property. /forums/images/graemlins/smirk.gif

 

[shvl73]

Diesels don't have spark for ignition, they use high compression. I would think the risk of it starting from hand cranking is small, but a risk none the less.

You have probably got it upright by now. This happened to Dad's Satoh Buck years ago while mowing a ditchbank. Upside down and noboby hurt except the tractor. TBN was not around back then so nobody pulled the injectors or glow plugs. Yep bent a rod. Dad fussed pretty hard at the guy who turned it over. Said he told him not to mow there. A few years later Dad turned it over in the same place. He was pinned under it with an electric barbed wire fence giving intermitant jabs. A passing motorcyclist saw his fingertips sticking up in the air and helped him get the tractor off. This time they were a little smarter and took out the injectors. When they spun it over with the starter it shot oil up on the side of the house. The Buck is mine now, still running strong but has some battle scars.

 

[hobbyfarm]

Just curious, was the engine still able to run on its side? Or did you kill it? Or did it die on its own from an air bubble? Or what??? /forums/images/graemlins/confused.gif

Hobbyfarm,

I had actually shut it down before the tractor was fully on it's side. Too many movies I guess, but as I was turning over I could see myself going up in a big ball of flame! /forums/images/graemlins/blush.gif /forums/images/graemlins/shocked.gif
Reached for the key with one hand and held on tight to the steering wheel with the other. Funny the goofy stuff that pops into your brain in a moment of stress. /forums/images/graemlins/grin.gif
