Did I go wrong????

if the pins and bushings look OK.... you got  2-3 times that much value just in the undercarriage..

I think you done good!  Looks like a bit of TLC and you will have a fun toy to play with. 

Anybody know weak places in the block to check for freeze damage? Rats/mice had chewed into the bottom radiator hose and there was no fluid in the radiator to see if it had any antifreeze. They said it did when parked but no way of knowing for sure if it was sufficient.

 If the bottom hose was chewed thru and most of the coolant leaked out, I seriously doubt there is any freeze damage to the block or coolant system. The problem could be rusty scale build up, from being exposed to the atmosphere for who knows how long a period.
 Many of these old engines have sat for decades and been revived. Just KNOW what you're doing with the fuel injector system before cranking it. Run Away's can destroy an otherwise good engine. At least be ready to close off the air intake before cranking.
 That would get put to regular use if it was in my possession. My OC46 track loader isn't much of a dozer

Ya know you never know what you have until you try to start it. it wouldn't surprise me if most everything is okay.  that motor seems to be a good motor. change the oil and you never know. price seems good to me. but the real deal is when you get it operating and play/use it. that in itself is worth whatever you have in it.  good luck and put another photo with you in the driver's seat when finished. It's always good to see these old machines brought back to life. they were a good old workhorse in its time.

So very true ! Good luck with it , may not be bad at all

Bee carefull power washing the radiator. I've seen a couple damaged with a high powered washer.

Is there a good way to see if the blower is locked up other than pulling it off? When I try to roll the crank with a pry bar there is a slight movement followed by a “clank” in what sounds like the front end (gears behind the front cover).

Another thing I noted is the exhaust valves and stems didn’t have any rust on them looking through the exhaust ports. I did not see any rust on the pistons looking through the sleeve ports. I can see one piston’s rings and they looked good with no rust.

Well found the problem today. Pulled the starter off, which needed to be lubed up and connected to a battery and cycled several times to get it to work properly. Couldn’t move the engine at the flywheel with a pry bar afterwards. Removed the blower to be sure it wasn’t locked up. It wasn’t but it did need a good washing out. Then I pulled the cylinder head. One of the liners was rusted pretty bad. I used a brass wire cup in a drill to remove most of it and then vacuumed it out with my shop vac. I then oiled the cylinder and hone up and tried to smooth it out as best I could. Cleaned it out real good and soaked it with PB blaster. After that the crank broke free pretty easily. That cylinder was going down. I got the piston out of the way and honed it again to remove the rust I couldn’t get to at the beginning. Bumped the crank back and forth when it would get a little snug and now it moves free. Neither cylinder had a ring ridge that I could feel with my fingernail. At the very least it will need a piston and a cylinder and some gaskets. The cylinder head wasn’t too bad. I used the brass brush to clean it up. My goal is to get it running long enough to see what else is wrong with the machine before I bury money in the motor and there be another issue. I am going to try to mount the blower and the starter again tomorrow.

On a cylinder kit, I’ve noticed there seems to be a 1, 2, and a three. What is the difference and how do you know which one you need?

Thanks Cal! I figured it was something along those lines. So the sleeve will have a number stamped in it?

OK. Thanks

Thanks. I will check it out once I see if she will runs and see if things operate on her or not.
