I have a chance to pickup a 1952 LP DC with hyds and eagle hitch. The problem is that its rearend is locked up. I have a 1948 DC with a good rearends but no hyds. Does anyone know if the internals are the same? If they are the same how much trouble sould it be to swap them out?

I would look at the brakes first. They seem to lock up after sitting a couple years. After that I would look inside, it only takes a little surface rust on some of those gears to lock it up. If a chain is broken you should probably be able to rock the tractor back and forth, and tell if there is some play before it catches. The clutch may also be locked up, then the stuck engine would keep you from moving, that was more of a problem on the foot clutch models. I haven't had problems with bearings locking up before.

There is another possibility for the locked rear end. One or both of the bearings on the upper reduction transmission shaft may have seized. I drained out the old oil and water from my '51 DC after rebuilding the engine and repainting it but I only drove it about 5 miles before it seized and stopped. We had to load it on an implement truck and pulled it on backwards with the bed winch skidding it on the floor by pouring oil under the rear tires. Worked great, no damage. Bearing holder turned black from the heat before it stuck. These bearings can be changed by only removing the bearing carrier caps. I will tell you how to do it if that is your problem.

Is it possible that it is the brakes that are locked up and not the rear end? If it is locked up... I will be interested to find out how you load it on a trailer if you have to.
Best of Luck.

The 1952 and 1948 tractors are different. Some components will swap out but what you have is most likely a broken chain. It is not a very difficult repair and you should adjust the chains anyway. The chains are the same,so they would swap, but it will be easier, and better, to simply pull the rear and top housing off the 1952 and repair it. You will loose the live pto, live hydralics, and eagle hitch if you swap, plus the clutch and flywheels are different, about all you will wind up with is a 1948 DC with an LP engine. LOL!

I was thinking about swapping the internals parts from the 48 to the 52. Then I would use the engine from the 48, as the LP engine is stuck.

I really think all you will need is a chain link. Regarding the engine. The blocks are the same but, unless the 48 has been overhauled with 4" Aluminum pistons, It will be a smaller displacement with 3&7/8 cast iron pistons, also, very important, the heads are different, if your 52 is a factory LP. If you use the 48 engine, you will drastically cut power, at least switch heads, but since you will have to pull the head, you might as well try to unstick the 52. new rings, a valve job and a hone is probably all it needs. You will have a more valuable tractor if you keep the serial numbers matching.
