engine casting #'s

Have been trying to put a list of engine casting #'s together. Here is what I have so far.

134
EAE 6015 F
EAE 6015 H
310605
310905
B9NN 6015 C
CONN 6015 C
CONN 6015 G

172
EAF 6015 J
310609
B9NN 6015 J
B9NN 6015 B
CONN 6015 J

144
B9NN 6015 A

I do not claim that any are correct because this is just a starting list that may need changes.

Does anyone see any wrong info or have any numbers you would like to add.

Thanks

Hello John;

Have you come up with any info on the gas vs. diesel block numbers. Not too long ago there was a question on the B9NN 6015 "B" as to whether it designated a diesel 172. From the archives it appears the "B" designated the 172 diesel engine. I'm just trying to confirm or refute. Thanks!

The B block is different just do not know how.
It could be it is a diesel block or could it be a non sleeve block.

If you look at the 134 blocks you can see the # most people use CONN 6015 C. From what I have been able to tell so far this is a original block with sleeves. The CONN 6015 G block is the same but it was a replacement block without sleeves. The G block was also used in some industrial tractors. The same thing goes with the 310605 and the 310905 block.


The problem I am having is I have seen the same # on a block no matter if it was diesel or gas. It also becomes difficult to compare #'s from blocks because you have so many 600's with 172 cu in engines and 800's with 134 cu in engines. So many things can get changed over 50 years that you have to take these #'s with a grain of salt and try to only look at confirmed cases and over all averages.

I have been trying to think about what is different in blocks with a different last letter. All these engines fit the same bell housing; so should be able to use the same flywheel. Yes a diesel and gas is different because of head bolts but I have seen no correlation with this and the #'s. The only thing that is still holding water is sleeved blocks and non sleeve blocks.

But please remember I am not trying to teach here. I am looking to learn so my info may be off some.

Thanks John. I understand your point about the difficulty of trying to decipher these things at this late date. I do appreciate your interest though as I find it interesting as well. I've been going back into the archives to dig out the info Tony Jacobs has provided and gather it together, but 4,000+ threads are alot to read. Thanks again.

John I had to go look at my numbers on the 640, but I remembered when I had the machinist mike it out for the rebuild he said it wasn"t a 134. He measured it and claimed it to be a 144 cu in. The block numbers on it are EAE 6015 J. I don"t know the history of the tractor brought it from a fellow about 10 miles away. I ordered oversize rings and filed them down to fit. Thats about all I know of it.

Is this a gas or a diesel engine????

Since you thought it was a 134 I have to assume you have a gas motor.
The differance in a 134 and a 144 is only about .12 in the bore and it would not be uncommon for a motor to be worn to this size.

So the question I need to ask is what kind of head gasket did it take????
The 144 (only available in diesel) might have been able to convert over to gas but it would still have the extra head bolts of the diesel.

Another point I just noticed is you have a EAE block and 144 engines were not even being produced at the time frame of this block casting #. So I have to assume you just had a wore out 134 but thanks for the comments.

One other question I have since you had this block tore down.

Did it have sleeves or not in the block????

John,
I just got home from an auction and there were a 1957 640, a 58 841 LPG and 58 841 Gas there. The block on the 640 was EAE 6015 J with a 76G:1 date code. The 841 LPG block was 310609 with a 84*V date code. The 841 Gas had a EAF 6015 J block and the date code was missing. The front left corner of the block appeared to have been modified. I went to this same auction last year and I distinctly recall seeing an 841 that had epoxy gooped all over the front left side of the block as if a rod had come through the side. I'm guessing this was the same tractor and the guy that bought it last year sanded down the epoxy in an attempt to hide the repair. The tractor had a very fresh paint job on it. If I had not been looking for the date code I would never have seen the strange looking area on the block. I'm confident that the part of the block with the date code got knocked out by the wayward connecting rod.

I'll check my 660, 850, and 951 in the am and post.

John it is a gas engine and the best I remember the gasket kit was for a gas engine. I do not remember if it had sleeves or not, I haven't rebuilt many engines and thats why I took it to the machinist. To be sure I had the right parts to put it together. I did recall him having a time to figure out what engine I had, as the bore did not match the 134, the pistons and rings were larger. and the block numbers didn't match the 134. I do recall the pistons had a stamp on them like power piston. Well since that block number wasn't produced during the 640 days I reckon I have a changed out engine, and a sweet little plowing machine.
Thanks for the info. Al

John,
As you have correctly stated the difference between the bore of a 144 (3.56") and the bore of a 134 (3.44") is .12", however that is NOT normal wear. .12" is almost 1/8" (.125"). A bore that was worn almost 1/8" would not hold enough compression to even start.
Whiskydog must have a 134 since his block has the EAE casting number and his machinist got fouled up on something.

1958 841D. All indications this block is original, the chassis S/N is X7785 with the first digit unreadable due to battery acid. Casting # 310609. This engine had no dynamic balancer (right up 'till the crank broke)which is consistent with tractors built before 1/1/59 and S/N 102357.

Awhtx I checked my serial numbers and its a 57 model also and the same block numbers as the 640 you posted. You have found its twin. I got mine cheap as it smoked badly and had just been rebuilt. I figure the rings were to small and they were upside down.
a good machinist is worth what he charges.

Yes you are right Alan.
I am thinking .012 with one side of my brain and reading and typing .12 with the other side of my brain.

Whiskydog
The EAE 6015 block was made from 53 to 57 so that fits the time frame of your 640 tractor.

The problem I am having is they did not start making a 144 cu in engine until 59 and it was available in diesel only.

So now I sit here and wonder how your block is so oversized. If it had sleeves I would assume your machinist would have just went back to standard 134 sleeves rather than try to figure out this odd size. If it does not have sleeves then boring a block this oversized would put you in the water jackets.

John the machinist had a problem with it also. He looked it up on the computer he has a deal to give him all the specs for all the engines,(Car Quest) He called his parts supplier about it. The parts guy just said he would send oversized rings and file them down.
He showed me on the computer the page it pulled up and it said what you say the best I remember said it was a newer engine than the tractor. I believe he said it may be an industrial engine. He said the crank and cam were 134s but the bore and pistons were 144s.
It cranks and runs well and I am likely to pass it to a grandson.

Hey maybe tou can help me here i have.a 1958 ford power master casting number 6015j
I found an engine on ebay out of some type of mower machine. Casting number 6015b
Would that work for me ? Thanks

You need the full number for anyone to be sure what they are.

The 6015J on your Power Master is most likely B9NN6015J or C0NN6015J, both of which would be a 172 ci 4 cylinder gasoline Red Tiger engine, which was the original engine on your tractor if it was a gasser when it left the factory.

If the one you're looking at on ebay is B9NN6015B, then yes, it is also a 172 ci Red Tiger engine, but it is a diesel, not a gasoline engine. It would bolt right up to the front axle support and transmission but you would need a number of things to make it functional in your tractor.

But it could be any other combinations of the first 4 characters followed by 6015B, which would probably be an entirely different engine altogether that might or might not fit in your tractor. If you get the full numbers for both we might be able to tell you more.

Sean I think that because the C0NN6015J block isn't identified as a gas or diesel everyone thinks it's a gas only block.

Adding to the confusion is my original 62 881 diesel with block casting C0NN6015J
