I am looking for a rebuild kit for my 706 which has a gas 263 engine in it. Would anyone happen to know where online or another source for a engine rebuild kit including pistons, sleeves, rings etc..... Anywhere for less than $500.00, I have been scouring the internet now and I have yet to find anything under $500.00. Just curious if anyone knows where I might be able to find it a little cheaper?

Thanks,
Joey

You will not find it priced under $500.

This forum has a kit for $519.00. Click on "Engine Kits" under Marketplace to the left of your screen. Hal

I bought the same kit for mine right here on this site. Good price, fast delivery, plus I am supporting the site.

6-cylinder IH gassers is no place to skimp on parts quality. Going cheapity-cheap-cheap is only going to cost you more in the long run. Hey, if someone can sell you the same name brand quality parts for less than the other guy, go for it.

Just don't set a price limit. All that will do is net you a pile of out-of-tolerance Chinese junk.

First off before ya dive in and BUY first you had best get the engine tore down and LOOK at the bore class of each cylinder as each hole had a letter stamped next to it telling you what class hole it was as they were not all bored the same and there are two classes and there for there is two differant OD size sleeves that are used . The after market sleeves are for bore Class A/B only and will fit loose in a C/D bore . This can cause the sleeve to snap off the top lip and get sucked down arond the rod and can send the piston into about 900 little pieces and thus send the rod out to see the sun shine . The sleeves MUST be a press fit and not a hand fit if ya want it to live a long and happy life . Now there is a way around this but it takes a few bucks more but you will only have to do this once and hat is o get the kit to make it a 291 up grade . you will have to bore the block and you order the sleeve kit with the special sleeves with the special flange to fit the upper contour bore and make them a Press fit . and this will mean about 15 more ponys when you do the rest of the updates .Or if ya don't want to do this then go to your Friendly local Case I H dealer and get the correct sleeves for the bore class that it is going into . So atleast get the head off and the pan off so you know what ya need as i am dead sure that this is not the first time she has been down in her life . You may find that the crank has been turned and there is no more to take off to true it up and it is nothing more then a boat anchor now . Next really look at the cam as there is no doubt that it needs rebuilt and new lifters need to be installed . It all comes down to the fact that they were just used to much when they were new . Myself i know each and ever quark about a 706 gasser and trust me i can make them run and run vary well. Oh yea keep in mind that they MUST run on 93 octane gas nothing less .

Could you explain to me why a these engines need high octane fuel? I have a 460 and according to my quick research it would be at 7.2:1 compression ratio and the 706 has 7.5:1 now there are only two things that I can consider a reason you would kill one on regular gas, the first being the heated intake and the other running too much ignition timing. Those two things combined I could see a problem especially with your intake charge already warm. However I am having a hard time seeing this. Please explain yourself to us.

Well that's what the owner's manual recommends... 93 octane. Good enough for me.

not to sound like a jerk but "what the manual says" is not good enough for me, I have enough background in engine math and building engines to question this. I have never however had this particular engine apart so I'd like to know why. I wonder if the old nasty chunks of carbon built up in the engine are causing the problems with predetonation once they get good and hot.

Let me help you cd1 as I hear the vet has been putting rubber on the pavement lately.

I'd suggest you go to modern view and search the vets previous posts. He has probably wrote a hundred or more lengthy posts as to his issue regarding premium gas, alot of which are based on his experince. He has been overhauling them for years.

I have no reason to doubt him but since 93 isn't available around here and the most I use mine is a few hours of hay bale moving, I just use the 10% ethonal. For someone pulling a plow for 12 hours straight under heavy load is a different story.

Let us know more about your theory on lower octane gas. Maybe start a new thread.
