Farmall H engine seized

First Thanks for all the help on my last post. Just to recap, I got my farmall running and it ran for about 5 minutes if that long. I was able to put it into gear and move it maybe a foot before it just died. I can no longer turn the engine over with the starter or by hand. I have remove the starter completely and still nothing. I have put the tractor into 5th gear and rocked it back and forth. Nothing on the engine moves.

Now before I started it, I checked to make sure that it had oil and that there was water in the radiator. Now I have removed the Valve cover and did notice that there was oil on top and appeared to be oiling properly (the engine turned over by hand very easily prior to the initial startup). Upon further inspection I found that although the radiator was full of water, the block had none. I drain the oil and found water in the oil as well. I have since put Marvel oil into the spark plug holes and it has been sitting for a couple of days and yet nothing. I have not checked to see if the tractor is stuck between gears, but it will roll in neutral.

Any suggestions on what to do next and or if there is any other type of quick fix out there. I really enjoyed the sound of the tractor while it ran although breifly. It did not seem to get hot at all even to touch after it died.

Thank you for your help and I apoligize for the long post.

The tractor does roll in Neutral. I do have the inspection plate for the clutch off, but have not taken a flashlight to inspect it as of yet. I will do that on Wed. or Thurs., my day off.

Can one replace bearings without pulling the whole thing apart.

Thank you again for your informative reply,

Daniel

Now a seized bearing would mean a complete tear down would it not.

Thank you for your time,

Daniel

Thank you for your reply,

So much to my surprise when I reinstalled the Magneto and turned the gas on it started. It did blow some smoke out at first and there was some ticking noise (sounded like lifters on a car engine) but that went away rather quickly. It was not until I put it into gear that it just simply died. Almost like it just ran out of gas. That is when I tried to restart it and found that nothing was turning. I removed starter and tried rocking it, but still nothing. Not sure what to do next. Spent more money than I should have but that is the chance you take,

Thanks

I did check to make sure that the tranny was not stuck between two gears and that did check out just fine.

I guess my next step is to remove the head. I really do not wish to do that just yet, but I guess this is not a good day to get suggestions on this board. I must be the only one that is off work or not out in the fields.

If I were to hook this tractor up to my truck and try to pull it, what gear should I put it in and or would I need someone to ride the clutch to get the proper response?

Thanks

Daniel

That for sure could put a rod through the side of the block....

block the wheels of the tractor.....jack one rear wheel off the ground..... thactor in 4th gear....jog the wheel back and forth..... still stuck.....pull it apart..... ..Don

Good luck! Dan

Thank you for your response. I have just been looking through my rather small/expensive shop manual and it says that I can renew the rod bearings as well as the main bears from underneath the tractor. Is this correct. I am assumming that I should be able to turn the crank to get to all the rod caps.

If so, and I did seize a rod or main bearing. Would it be possible to just replace those bearings with the same size or would the crank need to come out and be reground.

Thank you,

Daniel

I will see what I can find on Wed, or Thurs of this week and get back. I hope the crank is okay as I do not have the funds for a total rebuild on a $400 tractor that is really too big for anything that I need, but it does look cool.

Daniel

Will try removing the rod caps, or maybe the main caps as they would be easier for me to get to I think. The couple of pistons would be tough to reach the rod caps on considering their location.

Thanks,

Daniel
