well here it is guy"s overhalled the 706 ..by that i mean pistons,rings,sleeves and bearings.Now at 3 hrs. of running time(no load yet)i am hear a thud,not like a sharp knock. but a thud..Had a guy come out and listen to it.He was a IH machanic when they had the 300s and400"s in those days.He said the main bearings are too lose and the crank is bouncing a little.Now that im about aweek away from plowing I asked what to do.Since the crank cant be ground any more (30th over bearings) He said ...go right out and plow with it . He said he heard them a lot worse than that and nothing happened.. Well im kinda scard right now about it.Would sure like to get some opinions about it..Hope some of you will jump in and give me some... even if you have to chew me out a little. thanks in advance guy"s...Oh and why did it show up after 3 hrs?...What would you do? Tkanks again. Oh will it get worse when i run it more or plow with it?
 
Wow, I wouldn"t take that chance of working it. I"d pull the pan and check to make sure everything is torqued right on the rods and mains first. 3 hours sounds like about right time for a bolt to vibrate loose a little.I"ve seen that happen before. If everything is tight then you need to decide if you wanna run it, knocks never get better. Good luck
 
Well if ya did not have the crank mic.'ed when ya had it down and put standard bearings back in it or use the old ones and did not plasta gauge it Neither he or i ha ve a true idea of what is going on . Did you have the connecting rods rebushed ?? Could be a couple loose wrist pins ?? here again i don't have a clue what ya did . Did you fit the sleeves to the block ?? did they just slide down in ?? or did they have to be pressed in . Just stuffing in pistons and sleeves is not a rebuild . All you did was swap parts and called it a rebuild. So now you are going to school and you are going to pay tuition for this education.
 
For Gawd's sake don't run it any more.

Drop the pan and find that noise before you loose the engine.

There's either a bearing that is wrong, a wrist pin is too darned loose or the thrust bearing surface is hammering.

Morrie, take the oil filter off and look for bearing material. If you see any you know you are done right now. If not, well, maybe it is end play on thrust bearing but if it is it will go away when you push clutch pedal. If mains are actually loose enough to pound you will be able to move the crank up and down either under front pulley or under flywheel.
 
On some engines the main bearings have an upper half with a hole for oil, the bottom half doesn't. I've torn down a few tractors that somebody had put the wrong half in the block, and fried the mains.
 
Mine did that once. I bought it off the classifieds here man said it ran fine.under a load it spit sputtered. I took the carb apart on the tractor and when I put it back together the needle fell and got sucked up iin motor. Thought I blew it up till I saw the gas running out of carb. So if you find nothing wrong at the bottom end maybe it sucked up something. Oh and have never took that carb apart on the tractor again
 
I agree with the thrust bearing being loose. Check the end play on the crankshaft & get back to us.
 
I haven't noticed the center two mains getting loose any sooner on the 263. There was a lot of mix up on the thrust main bearing though as early model six bangers had some problems with them.
 
I would have worked the tractor the first minute it was running good after a rebuild.. Drive it like you stole it! Now it may be too late, but if your mechanic thinks its okay, work it.
