Hi everyone.
I just bought a dozer with no tag on the bell housing. It was advertised as a 53 OC-3 but I know that is not right. It has the OC-3 front wheels and an IXB motor (serial # 246 0129)but it does not have the Oliver name on the manifold casting and it has the old stub frame.It is painted yellow but you can see green underneath. I am not sure if I have a 51 OC-3 or a mutt. Can anyone help me narrow it down? It also has an anderson blade and a PTO on the back.
The front wheels and the IXB-3 motor are OC-3. Our 2 1952's had the stub frame, one had re-inforcing u-bolts back around the final drives (after-sale dealer mod).
If your knee-action springs are not shielded, that's a further OC-3 improvement over the HG.
2 of 5 IXB-3 engines out of salvaged OC-3's here did not have "Oliver" on the manifold. I'm not sure what that tells us!
It's pretty likely you have a 51 - 52 OC-3. Might be later - I don't know when they shifted to the longer frame.
If I think of it on my next trip to the shop, I'll check the engine numbers in ours.

thanks
If I remember right my dad said that the new frame came out inearly 52.If I knew how to post a picture I would.[/img]
One of my goals for this winter and it will need to be after Jan. 1, 2009 was to go through my old Cleveland service bulletins. I do have bulletins on frame changes and when they went into effect. Late HG tractors also have the change to the final drives as used on OC-3 tractors. Look behing the mag and see when you block was cast.
I was going to do that when I got it home, but when i went to get it I found that the motor will not turn. I took the head off and found rust so I am trying to back out of the deal. Can someone tell me what a parts tractor is worth?
John: You should publish the Cleveland Service Bulletins or offer them for sale as copies. What do you think about that idea? I know I would like to purchase copies if you would be open to that.
Thanks Orangeman

I keep reading about the manifold change to the one with OLIVER cast in it...was that a hit and miss thing or was their a distinct date for those?
Are they interchangeable with earlier OCs or HGs?
My information shows that the "Oliver" manifold started at 55GA022 which would be late 1950. That being said, the manifold is a part that often rusts out and is replaced probably a few times in 60 years.
The OC3 parts book indicates that 7WH940 was the change over point for the "full frame" which would be mid year 1952. There were a few different versions of the stub frame/transaxle attachment points in the late 1940's and early 1950's.
If you don't end up buying this machine I would be interested if you want to pass it on. Thanks
I now own the tractor, I am just trying to get it moved. I will put a posting on this forum if I decide to sell it.
Just a little update!!
I hired a car hauler to bring the tractor home on December 6. The OC-3 may not be a big tractor but when the tracks are frozen into the the ground it moves really hard!!!!!
I had taken the head off and have been putting Marvel Mystery oil to the cylinders for the last 2 weeks. I finally got a chance to work on it today(Dec 26) , I put a pipe wrench on the hydraulic pump shaft and gave it a little pressure and it broke free quite easy. The next thing I did was to get the battery and cranked the motor over for about 5 minutes to make sure that the valve train moved freely. Every thing looks good so now I will replace the magneto gear and button it up. After that I will probably not do much more until spring when it gets warmer.
