4000--1964 Diesel

Anyone know of the 172--4 cyl. 4000 sleeves and pistons are same for Gas and diesel? This site shows different for the two while others suppliers show the same for both. Also shows two different head gaskets with different size head bolts.

Absolutely not the same never were never will be . What ever other listings you are reading you are reading them incorrectly , no one lists Gas and Diesel as the same pistons . Head gaskets are of course different also Diesels have more head bolts than gas engines . If in fact you have a 1964 Ford 4000 with a 172 engine it will not have sleeves in it , ALL 1962 -1965 172 engines Gas or Diesel are sleeveless . I would suggest figuring out EXACTLY what you have , take it apart figure out what you need , and let the machine shop who is going to do the work source the parts for you . The difference between AMERICAN MADE and cheap CHINA JUNK is well worth the extra money unless you do care . Thanks Tony

I know what I have-- 172-4000 Diesel. I bought it new 1964 and has 5900 Hrs. Its never been apart. Head gasket leaks oil down left side. Thought I would rebuild since I will have to take head off. This site shows sleeves for it as other part books A&I--Tisco. Sparex only shows all parts as Gas.

Hello Miner , Well than if you bought it new and it has never been apart it DOES NOT have sleeves . I am a TISCO DEALER and TISCO DOES NOT SHOW SLEEVES for sleeveless block , pistons for sleeveless are listed seperately , however everything is listed under 172 engine , your block can be sleeved if you want but it cheaper to just bore oversize . Thanks Tony

The rebuild kits for Tisco shows BIFF 115am and Biff 115a and all other kits shows to contain sleeves and pistons etc. Then it shows each part separate. I wanted to get parts ordered then take apart since there is no local dealer. I'll take apart and then order.

I think the larger head bolts are in the Diesel engines, but I'm not positive, its easy to check though, just pull a head bold on the side next to the exhaust manifold and check it for size. The quick and easy way is with an open end wrench.

I think the main thing Tony is trying to get across is that the engines didn't come sleeved, however a lot of machine shops prefer to sleeve them instead of overboring them. There have been several articles here on the page where guys have said that the shop would not guarantee the block would not become porus if overbored, unless it was sleeved.

Unless you know for 100% certain that your tractor hasn't been apart and sleeved in the past, then it would probably do you best to take it apart first, check the cylinders and see what kind of shape they are in.

You might get away with just honing the cylinders and getting new rings, or you might find your engine has already been sleeved...

50+ years is a long time, unless you have owned it the whole time there is no telling what has been done already.

Remember we may not use these machines very hard now, but for most of them, the first 1000 hours of their life were very hard, they were the work tractor on the farm or wherever they were bought. Things broke and were sent back to the dealer for repairs, some got engine swaps, some got sleeved... etc etc all in the first few years of their life, so even getting a tractor when it was 2-3 years old can leave a large gap in knowing what happened to it, until you get it apart.

It has been on this farm its entire life and not been apart. Its only had a water pump several years ago. Its been a very good tractor. If they would just build tractor now like it. But they wouldn't sell any.-- LOL-- It worked hard as you said in the beginning but just light work now. When I do anything I just go to it. Its going to out last me. It will be here until they have may final sale.--LOL--I've bought a lot of tractors through the years and never had one this good. I have new green ones now and are just not built to last.

First off BIFF 115am and Biff 115a are both for gas engines.

Second could it be Tony is right and you have this block.



Third could it be they list all the 800; 801; and 4 cylinder 4000 parts together as many interchange over the years so this is making you think 4000's have sleeve when actually they stopped putting sleeves in engines before the 4000 came out.

Forth could it be Tisco only sells rebuild kids for sleeve blocks so that is why you do not see the sleeveless parts listed.

Fifth since you can not order rebuild parts before you tear the motor down (how you gona know what size crank bearings to order) why not tear it down first; take a picture of the sleeves in the block; and come back and tell us na na na na bo bo I was right all along it does have sleeves.

Hello John , As for you Third response they do list everything together for 172 gas and or diesel and list everything separately under pistons , rings , bearings etc. , etc. kind of confusing for the first time user . As for your Fourth response rebuild kits are for sleeved blocks only without bearings and or size must know to order with bearings . Pistons for sleeveless are still .020 , .030 , and .040 . Pistons for .010 are gone as are .001, .002, .003 bearing kits I figured .040 pistons would go down the road but they still list them . Thanks Tony

I'll post pictures after I get apart. BIFF 20 is what I should posted. link_disallowed shows same. I called a NH dealer (100 mi) and was told it came with sleeves and they could get rebuild kit. All in frame rebuild kits comes with sleeves. You can get each piece if you need only rings etc.???????????

Your NH dealer is in the wrong 4000s w/172 engines don't have sleeves! Look for yourself on the NH parts website.

Great; I will be looking for those pictures.
