Rolled my kubota 7800... Now it wont turn over. Please HELP

tombodett · Aug 7, 2015

Well boys Ive done it this time... I was brushhogging on an incline, came to a fallen tree on the ground, tried to back up, couldnt. Tried to pull forward maybe a foot. Started to slide towards the ditch and like slow motion, I rolled over onto my side. Called a buddy he came over got me turned over real easy, not so much as a scratch on the tractor or me. THANK GOD.
I checked all fluids except the battery acid, everything checked right on. So I tried to start it. It turned over just fine for a couple of revolutions then battery clicked and wouldnt turn over any more. I took the battery out and took it home and filled it back up with acid and put a charge on it for a couple of hours. I went back out and got the battery in it and tried to start it. It turned over maybe a half a revolution and knocked and wouldnt turn over any more.
Then I got on here and figured out I did wrong trying to start it. Now Im letting it set over night and plan on trying again in the morning, Should I or should I just plan on getting it to the shop for a rebuild?
Any insight would be greatly appreciated!

Pull the injectors or glow plugs and then turn it over. You may have a fluid filled cylinder.

The post above me sounds about right. You got to make sure there is no oil that can bend the rods when you start it up. I don't know the specific mechanics, but--I think--the worse thing you can do is restart the engine without clearing any oil.
Good luck.

To TBN Tom. Are you "leaving the light on?" I bet you have heard that one a million times.

When I rolled mine over on it's left side. I had it righted in about 2 hours. I then let it set for about 8 hours before I even tried to start it and it started right up just like always. Guess I was lucky.

Never add acid to a battery after the initial fill. If it spilled acid of any significance, it toast. If it did not spill, add distilled water. About hydro-lock, you will probably be OK if you do as told above. You probably did not hurt the rods or wrist pins. Good luck! Glad you were not harmed!

Why is that? I have added acid to cell when the specific gravity was low after a charge. You just need to ensure that what you are adding is the same specific gravity as the other cells. Of course we had big cells on the submarine and 126 of them..

Thanks guys for all your input. I plan on going back out in the morning and loading it on a trailer with a winch and take it home, pull the injectors and try and roll the oil out. I will keep you all posted.

Yeah I should've got on here first but I was all worked up and apparently not thinking clearly. But you know what they say it's never good to should on yourself. O and I'll definitely leave the light on for ya.

A bit of an 'aside' (and welcome to 'tombodett' from Downunder), I was on Oberon Class diesel boats ['O' Boats] for awhile... heaps of fun <sarcasm> keeping the banks of batteries in top form.

As the USN boats were/are nukes, I take it that your banks were for back-up?

Update. I winched her up on a trailer, got it to the shop, pulled the fuel rails and the injectors. I put a half inch drive on the crank and hand cranked it a couple revolutions and it looked like an oil Geiser. Then I cranked it with the starter a few times and it spat even more. Put the injectors back on and the fuel rail bled the air out of the diesel lines tightened the injectors and she fired right up.
The summary of the story is if you roll your Kabota tractor the rings are to sealed to let the oil drain back down past the piston even if you wait overnight. So just plan on pulling the injectors and Emptying the Cylinders before you try and start it .
