Jeff, I just overhauled a B, that included rebuilding most of the transmission/axle assemblies in addition to the engine. I agree with the starting point being the purchase of a good shop manual and parts book, available from this site and others. If you are fairly mechanical, it is a relatively straight forward process. I started by getting good info on where I was at with compression, tollerances, etc. In my case, a complete overhaul was necessary but not all jobs are the same. Many of the "specialty" tools required can be rented. I consulted with the folks on this forum when I had questions and my B and I came through it fine!

Jeff you can get a manual on this site just look to left and click on tractor manuals. They are also available at TSC stores. That is the fist step.

Go to amazon.com and do a search for "tractors" or "antique tractors". There's tons of books out there that cover anything you'd have to fix on your B. I have one here someplace, can't remember the title, but it covers a ground up build on an A, which is essentially the same thing as your B.

Once you have these "how-to" books, be SURE to also, like mentioned below, get a service manual for your specific tractor. They're available through this site. The general how-to books won't have all the various exact specifications for your model. Of course, all the how-to books tell ya to get a manual too...

Have fun!

Oh come on...you know good and well he means to rebuild the engine. Forty years ago, I never heard anybody say they were going to 'rebuild' anything....they overhauled it. Maybe it should be spelled over-all....because you go over it all, repairing the worn out parts.

Now that's an interesting question and I'll tell you why. I'm not sure what an "overhaul" is. I hear people say it all the time. For me, when I get something old, I don't fix anything that ain't already broke. I can see the logic of maybe going in and changing part "A" and while your in there and got it all torn down, maybe replacing parts "B" and "C" on spec because they are hard to get at and likely well worn but only if they are cheap. I get a service manual and fix only what needs fixing. What exactly is an overhaul?

An "overhaul" is fixing what needs fixing on a major component all at once, instead of piece-meal. "Piece-meal" is doing a little here and a little there - as in patching. "Patching" is..... well - what many of us do to old tractors, as in barnyard engineering. "Barnyard engineering" is patching in an unconventional but creative way - using whatever is handy on premises. Ah, but I digress.....

I know mark thinks I am yanking this poor kid's chain, but really I am not. So overhaul is essentially what I was saying that I would do around here. You tear down the engine or some other major component and fix what needs fixing.
You do not necessarily replace everything that might be wearing out. I have heard people say that they tore down an engine and replaced virtually every bearing, ring, or other wearing part and made it "like new". That seems like a waste to me. Just trying to get an understanding.
I am "mechanically backwards" as is well known.

I do not understand the logic behind tearing an engine apart, then not replacing all the wear parts while you are in there.

For the engines I have overhauled or rebuilt (don't nitpick semantics with me), the time and effort to get it apart, clean it up and put it back together is the largest investment. That is not to say that parts are cheap, but if your time is worth anything at all it the biggest part of the job. Then there is the downtime if it a working tractor.

I only want to do it once. If it fails because of a part that could have been easily and cheaply replaced while I was in there, then it was a half-assed job, and I don't intentionally do half-assed work.

At least that is how I see it.

I can see what you are saying. So pretty much an overhaul (and I was never arguing semantics, that was the other guy) COMPLETELY replaces all the wear parts from your perspective. I have to agree that this is probably the wisest course. When you really get down to thinking about splitting tractors and dumping fluids and all the incidental costs of a total tear down, it just makes more sense to replace it all. Especially if you are going to put a showy coat of new paint on it. I appreciate the answers and your patience. I have a 2N here that I will be tearing into this summer. It will be my first time inside an engine and I am trying to get a feel for what is involved. Pretty confident I can handle whatever comes up but am trying to learn all I can. If I don't screw this up too badly then maybe I can work on my Farmalls as they need it. Fortunately, none have needed it so far! Regards, Dave.
