Sleeves in a B block

A good friend is bringing me his b farmall to fix and put back together. He left the exhaust uncovered and two pistons are stuck. What I need to know is if it has sleeves and how they come out. Pulled,pressed, or bored out? He says he is bringing it to me with new pistons and sleeves. Thank you.

A "B" will have what is known as "wet sleeves" there will be sealing rings to seal the coolant at the bottom of the sleeves. A sleeve puller would help but with a little care and imagination one should be able to pop them out.

Actually if they are rusted up pretty good you maybe able to get them out just trying to crank the engine over by hand with the head off!
 
Wet sleeve and they can be popped out by using a piece of 2X4 and a bottle jack from under it. I've popped a good many out with a 2X4 and hammer also
 
Thank you. I'm familiar with set sleeves on DT 466s and JDs. I appreciate the information.

Hey Rich, I was hoping I could do it in frame. I'm sure I'll be asking more questions. I'll email you when he brings it to me. Really not excited to work on it when I need to be working on my tractor. Thank you sir. Since you are older than me.

Way back say 5=10 years ago when I built my BA I took a locked up B and install the parts of an A engine to make the BA. The A had hit a tree and that in turn broke it into a number of piece and the block broke so I took the B block and put in the good A parts and made to BA so yes I can probably help you by e-mail or phone
 
how do you use a sleeve puller with the piston stuck in the sleeve. If its rusted real bad you need the crank out and the block removed so you can press sleeve and piston out together BTDT
 
There is no such thing as an "in frame" rebuild on an A or B, not if you are going to do it right. The engine block itself is the frame on the front end of the tractor, and you can't get the crankshaft out without removing the block from the torque tube and the steering box from the front end.
 
Dave, I well aware of what an actual in frame is. What I was communicating was the fact that I would not have to remove the block to accomplish what I have planned. I'll I wanted to know was what kind of sleeve I could expect to find in a b Farmall.
If I post another question please feel free to not respond. Thank you.
 
I know everyone has different ideas of what a particular repair procedure may entail. But around here an "In frame" overhaul would not include removing the crank. New main and rod bearings, yes but done with crank still in the block.

I've worked on many engines over the last 50 years from little Farmall BN right up to 16 cylinder Cat Diesel generators and can not recall any where you could remove the crank while engine was "in frame".

Some of those Cat 16 cylinder diesels you can remove a connecting rod with out dropping the oil pan or the cylinder heads! BTDT!
 
I got it loosened up. I'm going to drop the pan and put rings and rod bearings in it. Thanks.

One thing that just came to mind while thinking about this Farmall B was a problem I had many years ago with my BN.

Shortly after rebuilding the tractor from the ground up I was noticing signs of coolant getting in the oil. I was thinking that one or more of the liner seals had been damaged installing the liners.

Trying to recall all the things I did checking it out and believe one thing was to remove and inspect the liner seals and everything looked find.

Then I got looking at the head gasket and something did not look just right. After some searching in several books and catalogs I found that there was a change in the head gasket design. I determined the one in my gasket kit was for a different S/N range than the engine in my BN.

Replaced with gasket for my S/N range and now 30+ years latter no more signs of coolant leaking into oil.

Just thought this might be something that might come in handy for RBnSC or anyone else.
