D6JL is power unit engine. No sleeves. 1976 or later. I would use it. I have a D6JL and C0NN diesel engines. Just cores.

Many years ago I had a 59 871 diesel with the non counter balanced block and crank, but don't remember what the casting numbers were.

My present 62 881 diesel is original with block casting number C0NN6015J

Info I've found only says it a 60-64 172 block

Doesn't say if it's gas, diesel or both

It could be that the later castings were designed to be machined for ether app.

Just thinking out loud.

Putting this together may we deduct that the letter "B" indicates it's a 172 diesel?

Here's some info from the archives. The first is by the courtesy John Smith. It appears from what info he provides the letter "C" designated the 134 engine and the letter "J" the 172.

The second is by Tony Jacobs.

According to my IT Manual the 144 was not used in the 801 series.

Looking at the info by Tony Jacobs the letter "B" was used in 1960. The number was taken from a 801 series tractor with a diesel engine.

From John Smith

"The block casting code will tell you what it is. Here are the codes -

EAE 6015 - 134 1953-1957

EAF 6015 - 172 1953-1957

310605 - 134 1958-1959

310609 - 172 1958-1959

B9NN-6015C - 134 late 1959 early 1960

B9NN-6015J - 172 late 1959 early 1960

CONN-6015C - 134 late 1960-1964

CONN-6015J - 172 late 1960-1964"

From Tony Jacobs

"I would say you have a Mid to Late year 1960 Ford tractor . If the tractor was a 1959 the hood decal would read 871 or 881 not 801 as 1960 tractors do . The casting number B9NN-6015-B is a 1960 casting number only except for late 1959 tractors or early 1961 tractors with leftover production engines in them ......"

Putting this together may we deduct that the letter "B" indicates it's a 172 diesel?

Make sure it has the casting for a diesel balancer.

6015 just means "engine block". The leading 4 characters say what year the casting was designed, and for and by which Ford division it was designed. The trailing letter(s), j & b in this case, merely serve to differentiate between engine block castings that were designed in the same year. So there were literally dozens of Ford engines made over the years that ended in 6015B and 6015J, so unless you can provide the leading 4 characters of both numbers everyone here is just guessing.

From what you said I read you have a 58 diesel with 6015 J casting code.

First off since the diesel did not start to 59 I would like to see date codes if it is really a 58.
Second since your J block is diesel I guess that blows out the water that J is a gas block.

Now that we got that out the way lets dig deeper.
The EAF 6015 J ... 310609 ... B9NN 6015 J ..... B9NN 6015 B ..... CONN 6015 J are all 172 blocks.
If it is a 172 block it will bolt up and work. Heck the smaller 134 will bolt up and work just has less power.

Some claim the difference in the J and B block is one has sleeves and the other does not.
Others claim the difference is one has the factory balancer.
Some claim the B block is a industrial motor but I have seen tractors with it.
For me I lean to the B9NN 6015 B as being a 1959 block with the factory balancer that was used in late 59 and into 1960. But with so much wrong info being passed around it is hard to tell unless you have personally taken both apart. If I am correct and you now have the B9NN 6015 J block that may be why your block finally came apart. The rod threw because the motor does not have a crank balancer.

The only real difference in the gas and diesel block is the holes for the head bolts and crank bolts.
This could be why both diesel and gas motors can have the same casting numbers.

So I would want to know from the seller of this 6015 B block.
Is this a diesel motor. Pretty obvious question.
And does the motor have a balancer installed. Only way to be sure is the take the pan off.
I would not buy a unbalanced diesel motor as a replacement.
No use asking for more trouble down the road from a unbalanced motor.

I know I did not answer your question but gave you what I know.
Hope it helps as I see you drug up a 2008 post asking me the same question.

B block is 172 diesel
J block is 172 gas
I might have a 172 J gas engine if that's what you are looking for
