4-150 engine rebuild

Other than the time it takes, overhauling it wouldn't be that bad Bore the block, put in oversize pistons, replace the brgs and do the heads, pretty straight forward.

Those engines got named "throw away" because they don't have sleeves and many thought once the cyl are wore you just throw it away because you can't replace the sleeves. Cat makes several different oversize pistons and even says that you can bore just one cyl.

What kind of load are you putting on that 4-150? Good luck, WB.

3208s are certainly plentiful. You could check Worthington or a host of other salvage yards for combine engines or even good engines in White or MF tractors in which the 3208s were used. You might also check the Cat dealer; they would probably have a good supply of parts engines. The engines they pull out are in all likelihood in as bad or worse shape than yours. I have not rebuilt one, but as with any motor overhaul, with the right reference materials, you should be able to do a fine job. Cat dealer can get you parts, overhaul kits, etc. I have even priced a complete Cat reman 3208 and they are pretty reasonable. With a good core, ballpark $7500 - $8000. By the time you factor in your time, that isn't too bad. But then a guy has to ask himself, is the tractor you're putting it into worth it? I got lucky with the 4-210; it has a healthy 3208. The 2255 has one that is getting tired, but it will still develop incredible power.

This is set up on the camshaft gear or the injection pump drive gear, it's been a while, and I can't recall exactly how it is set up. I have CAT from a 1500 or 1800 Massey that I was always going to tear into, and never seem to get around to it! There used to be a few of those around here, as well as the 4-150's.
