JD 60 Gas In The Transmission

Hello,

I have a 1955 JD 60 that is emptying the gas tank into the transmission. There is no longer any shut off on the bowl so I have been pulling the bowl off when not using it. What do I need to replace to stop the drainage. Thank you in advance for your help.
 
The only way fuel can get in the trans is from a leaking needle and seat in the carburetor. The tank also needs to have the shutoff replaced so that the fuel can be stopped when not operating the tractor. Gravity based fuel delivery is like having a fuel pump running all the time, even when shut off, so shutting the fuel off is standard operating procedure on all gravity fed tractors. Jim
 
Better check the engine crankcase too, as it will have to get full of gas before it could get into the transmission through a bad crankshaft oil seal.
 
If the engine crankcase was saturated with gasoline, it could possible flow past the belt pulley side main bearing seal into the trans. I see no other way. But the OP might be saying something different, like the crankcase is overfilled???? Jim
 
better get that carb off and fixed. i have a very hard time to believe you crankcase is full of gas, and if thats the case you would be doing an engine overhaul due to no brg. lube. and the chances of it getting into the transmission is even less likely because i am sure you must check the oil level once you know this is happening. have a better chance on winning the lottery.
 
The oil pressure activated fuel bowl may be malfunctioning. If so you need to fix it , replace it or switch to a bowl with manual shut off.
 
Well I will take a guess at this. There is no manual shutoff because there probably is an oil pressure activated shutoff. When there is no oil pressure the gas shuts off. There is a diaphragm in this oil pressure activated shutoff that can perforate and allow gasoline to drain out of the gas tank and into the crankcase via the oil pressure tube that goes to the fuel shutoff. Removing the sediment bowl will not stop the gas from going through this diaphragm and running into the crankcase. It only does this when the engine is not running. I also have a hunch you are confusing the crankcase with the transmission, easy to do if you have never been around a two cylinder Deere. I might be wrong but I think this is what is going on. The diaphragm is fairly easy to replace for a person who knows what he is doing.
 
Thank you fixerupper. Yes you are right, it is the crank case and not the transmission. Guess I had a major brain fart on that one. The diaphragm makes sense. After thinking about it, I 1st noticed this problem when I took the tractor out of winter storage and the gas tank was bone dry. After getting it started a clear liquid came out a bolt hole in front of the flywheel. I originally thought it was a water condensate build up which also seemed odd as it had never happened before. The tractor doesn't get ran a lot. So I will find a diaphragm and get that changed out and then give all of the oils a change. Thank you again for the help and sorry for giving wrong information. Thank you everyone for your in puts.
