I recently started cleaning up my john deere B that my great grandfather purchased new in 1945. It has not ben used regularly since the 1970's. I started it and pulled it into the garage about 5 years ago. I just started to clean it up and try to get it in good running condition again. I pulled the drain plug on the motor oil and nothing came out, so I put my finger in the hole and its just solid Goo sludge like junk. I expected it to be nasty like milk but not like this. is there any way go get this junk out?
thanks

Hiya,

A couple things may and one will get it out. First, I would try is a torpedo heater aimed at the sump for an hour or so to get it nice and hot, that should get it to flow. If that fails, put the drain plug back in, dump a quart of Kerosene in it, hit it again with the heater and try again. If both of those fail, drop the pan and scrape it out.

In the 60's and early 70's there were issues with oil that was overheated that, when cooled, would solidify into a rubber like gel in the oil pan.

A lot of old time farmers used thicker oils because they thought it offered more protection... That probably isn't helping you. :lol: Don't forget to check the transmission case too. Hopefully your luck will be better back there!

To make sure your heirloom tractor survives long enough to be handed down again, I would suggest that you go far beyond simply scraping out the pan. There could be oil pooled and solidified on the bottom of the pistons and bores. There could also be buildup on the oil pump which might hinder its ability to push oil through the system. Or worse, it could throw a big chunk of sludge into an oil gallery in the engine and cause a blockage. Think of it like your tractor having a stroke. You'd never know there was a problem until it was too late.

There isn't much to these old tractors so don't be afraid to really open it up. Wash everything in gasoline or mineral spirits and scrub it clean. Re-assemble with a good assembly lube, new rings and fresh gaskets after making sure everything is still within spec. After 70 years, it might need a little freshening up anyway.

Good luck!

on some of mine, i put in a couple gallons of diesel and let that soak a few days, then i took a dip stick and taped a rubber line to it a couple inches down from the end, then hooked my compressor to it and shoved it back up the hole, the end of the stick acts like a scrapper and air pressure to blow big chucks up. That stick is tough to scrap with and flexible enough to push around in the blind hole. The only down side is chunks can get caught up by the oil pump, so i always flush a couple times with diesel.

The only other option is to pull the block because there is no "oil pan" to take off. The drain plug is cast into the main case. The good thing about doing that is its not to difficult, and if you are careful, you can reuse the head gasket. With the block out of the way its a big hole to get into and really clean it out and a lot easier to flush.

oh yea, my edit, if the crank case was that bad i would expect the transmission to be worse, drain out what you can, put in 5 or 6 gallons of diesel and drive it around, rise and repeat till you can live with what color the diesel is when it comes out haha

When I did mine I took it all apart. Head and block apart. I'm glad I did as I had to scrape sludge from every nook and cranny. I also took the oil pump apart which was full of crap. It's a lot of work but was worth it.

You may want to pull the oil pump and check the screen. A friend of mine just purchased a 41 JD H and after starting had no oil pressure. Before starting it he changed the oil and found it drained in clumps. The screen on the oil pump looked like it was coated in tar.

I dumped some kerosene in to clean it out but have not had a chance to run it yet , I have been waiting on a magneto since November. I am starting to wonder if they will ever get them back in stock. I sent mine to Roberts carburetor to get rebuilt and they said it was too worn out and would be cheaper to get a new one. I am still waiting on them to get the new ones In stock, its a wico xh 1042.

The wico x is pretty common and easy to find, along with repair parts. There are several on ebay. JD switched from the wico c to the x later in the production runs of the A and B.
