Glad you weren't (seriously) hurt, and tractor is okay.

Subscribed.

Glad you weren't (seriously) hurt, and tractor is okay. The same hear. Luck was on your side for sure.

No safety switch did not shut her off, and no my britches did not make it to the wash. I threw them in the burn pile.

Na but since we're getting personal, the worse residual affects I think I'm going to have is post traumatic stress disorder. I've already dreamed about it twice,and **** I couldn't get it up on the trailer without getting a little "jumpy"

I'm going out this morning to change the oil and filter, and grease her up.

Stress will do that. Talk to your doctor, he may be able to prescribe a little blue pill. - Not sure why you were trying to do that on a trailer. I wont ask!

Glad you are ok.

After I put mine over on its side. I am extremely jumpy about it going over again even after putting wheel weights on. I was working in the spot this weekending that I rolled a month ago and was creeping along, even got a cramp in my leg from tensing up.

Well I got the oil changed and now it's only got what seems like %75 of the power. There is no noticeable knock, smoke, or vibrations.
I am at a total loss. I have heard that maybe I need to have the injectors re-calibrated, since I had them apart. Any educated guesses would be greatly appreciated. I don't want to take it to the mechanics at the dealer and pay $85 an hour.

Pull the injectors and take them to a shop that rebuilds them. My skidsteer has a Kubota engine and I just had them checked. It cost me 20.00 an injector. One was bad and the parts cost more than a new one so they replaced it with a new one after calling me

Your probably not going to like my answer, but there is a chance you bent a rod when you tried to start it at first, it might have had fluid on top of the cylinders. There was someone with a different brand tractor that had flipped his, tried to start it afterwards, and he bent a rod. He had pictures of it when it was taken a part and it was bent pretty bad. His also still ran but compression would be down on the cylinder with a bent rod.

I would certainly look at other stuff first though, but I never heard of having anything having to be done to the injectors like you are describing.

tombodett · Aug 24, 2015

I have heard of that before as well. But like I said there is no vibration whatsoever, and I would think if there was a bent Rod it would cause vibration.?.

A co-worker of mine just had an old tractor engine repaired (water jacket leak welded up) and he put the head back together himself and noticed one cylinder was weak. To make a long story short, he didn't install something right which caused the push rod to get bent.

At first he suspected the injector and moved it to another cylinder to see if the problem followed ... it didn't. Then he thought the fuel line was crudded up so he ran piano wire through it and sprayed it out with brake cleaner ... still had a problem. Pulled the cover and that was the Ah-Ha moment - bent push rod.

dodge man · Aug 24, 2015

Diesels run pretty slow and a bent rod might not really throw the engine out of balance. I'm not sure either way.

As far as injectors, I think your engine is a mechanical injected engine. The injection event is pretty much controlled by the pump. as far as I know, there would be nothing to do other than install the injector and hook it up. Unless you installed the injector wrong, I'm not sure what else there is to do except to start looking at other things.

Glad you sustained no serious injury other than to your pride, welcome to TBN. I have broken my share of expensive things including bending a rod on a PWC engine but I have to challenge the idea a starter that only clicked generated enough pressure to bend a rod designed to withstand compression of a diesel engine. So what about it folks anyone actually know of a bent rod caused when the motor never turned over or the liquid was not ingested while the engine was running?

I guess in theory since it ran for 10 sec the oil could have seep in and caused it but that seems unlikely.

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 .

No... The oil got in there through the rings.

Could be a bent rod, a local mechanic has a strange shaped rod from forced movement. A loaded grain truck died (engine locked) and they roll started it with a large tractor. The offending cylinder's rod simply bent and engine fired and ran for a good while. When it was taken down from loss of power the bent rod was found. If one Cylinder fires and forces another to compress some oil and bend a rod it could clear and run it doesn't take a lot there is not much room in there.

I'm glad your ok and I really hope there are no damages to the engine.

I'm with you. That would have to be one massive starter motor, or one really crappy con rod.

Injectors don't care if the engine flopped over for a breif time.
