51 Case LA....DEAD

Decided to take a look at the LA I got from the neigbor. It had been sitting awhile and I knew it was stuck. I wanted to get the valve covers off and then the heads to put some penetating oil in the cylinders, let it soak and maybe break loose. Everything was coming off great. Found a bent push rod on #2 exhaust and a sticky valve. Got the head lifted off with no troubles. The cylinders looked fair with some surface rust..not bad we were thinking. I tapped on the #4 piston with a block and hammer and it moves....however nothing else did. #4 piston is broken. Anyone out there need a LA restoration project? Its in pretty good shape right now. Im not going to be able to get to it for a while and its just going to deterioate more.

To whoever takes it, I say, never give up on that LA it will make a beautiful tractor. All the parts that you need are out there. Don Livingston will have alot of them, maybe the piston. I got my rings from Carter Engine and Machine in Amarillo, Texas who got them made up by Hastings Manufacturing. The propane does not normally wash the top of the cylinders down like gasoline does, so there is less wear at the top of the cylinders. Hone the cylinders good and install new rings, fix the head, and put it back together. The rods have babbit bearings that are shimmed on each side. So to get a good fit on the crank journal takes time. I usually shim and torque each rod to size in a vise then move it to the tractor and with the correct shims on each side, install it. Then remove one shim to see if it is too tight or OK. This will set them close, and that is what you want. Get the head surfaced, replace all worn valve guides then grind the valves and seats. LAs take time so don't get discouraged. If you have a shop to work in that will speed it up considerably. Because it looks to all be there you won't have to buy a lot of extra parts. ---Derrol in Texas---(Case LA Propane in Tractor Photos)

Cleaning and painting makes a difference. This grill was bent and damaged, but with help from a friend with a wire-welder, and some careful clean up it looks good again.

OH MY. Thats a fine looking tractor. I'm really liking that paint. I live next door to Amarillo. A freind of mine told me to take my JD model D block to Carter.
 
The rods and pistons can be removed without removing the oil pan. Just work through the side ports on the engine block. Wipe out the pan good and your ready for fresh oil. Specialty Compressor in Borger, Texas has been cutting out my head gaskets from 1/16th Copper sheeting material. My first one worked well but haven't had a chance to try the second one on my second tractor yet. When I set the torque it was set good but I did a retorque just the same. The head was resurfaced so it did well, no leaks. The pictures are of my 1949 Case LA with the Emergency brake system. I thought Case Power White rims looked nice, and different. They remind me of white shoes that my Dad used to call "Ice Cream Shoes". So here is a Case LA with "Ice Cream Shoes". I am also including a picture of my friends helping me load this tractor at the salvage yard. Doesn't look so bad with the new tires, But setting flat on the ground with no tires, rims or drawbar it did not look so good. It must have been used behind another tractor before being set aside. ---Derrol in Texas---
