Help - Jubilee Oil Drain Plug Stuck

Help,
I am trying to get the oil drain plug out on my '53 Ford Jubilee and I can't get it to budge! I have a new replacement to go back in its place so I can see that I am trying to turn it the correct direction. The square plug has been rounded off by somebody before me and I can't get a good grip on it to turn it with a cheater bar even. The tractor sat for several years unused in a shed and runs just fine. The oil in the pan doesn't look that bad and the filter wasn't that nasty. It makes me wonder if they changed the oil by dropping the oil pan or by pumping out through the dipstick hole. Does anybody have any suggestions on how to loosen the drain plug? I am trying to turn it now by using a hammer and chisel. Here is a picture of what it looks like if you don't know:

As you can see the screen makes for a big plug with lots of treaded area. That's probably why it's being so stubborn to turn. Any and all suggestions are welcome.

Thanks,
Billy
 
file it a lil square then use a pipe wrench and a small jack and block of wood to hold the wrench.. in bad cases might have to weld a large hex nut on it.. or use a chissle to tap it around.

I will almost bet you my mortgage there will be no gasket on that plug and the previous owner felt it was a better idea to tighten that plug to death instead of replacing the .25 cent gasket. As Soundguy said best course of attack is to file or grind the rounded head square get a wrench to fit then pin it with a hydraulic jack and wood so you can get a good pull with a wrench and bar. It'll go. I have also used a large 24 inch pipe wrench to break them when in this condition.
 
no big deal---take large pipe wrench and put it on the big round part of the oil plug---maybe a cheater ---good luck
 
Thanks for all the GREAT IDEAS!!! I didn't mention earlier that I tried a big pair of vise grips but just couldn't get the leverage I need. I now have soaked at down a couple times with PB Blaster and have tapped on it some. I will let it sit overnight before I try anything further. I have an angle grinder that I can try to grind the sides back square. I like the idea of using a small jack and a block of wood to pin a large pipe wrench in place. I saw some big pipe wrenches at Northern Tool a couple of weeks ago when I was there getting a large socket to drive new freeze plugs in. They have a 48" long one for $50 but I would probably have to get my wife to hold the tractor so it wouldn't turn! Maybe I will just go with a simple 24" long one instead.

Thanks again for all the great ideas. I will keep you posted as to the outcome.

I know, the liquid wrench on an oil plug is wacked. I did spray some on a year old oil filter that had been installed using oil on gasket. Could not budge it with wrench. Soaked edge with penetrating oil and it finally started to turn after 10 minutes or so. Oil had burned/stuck on mounting plate.
I doubt it (liquid wrench did much but it made me feel better as I struggled) (New filter installed using silicone on gasket)
 
if you can get the 48" one on the plug after you clean it up.. get the jack and wood on it.. 48" is a good lever.. that's what you are shooting for.. good purchase..

I use a hammer and chisel about three good licks and spin it out with my hands seems like vise grips and pipe wrenches may be what messed it up to begin with.

I ended up having to use a big pipe wrench and a cheater on mine. About the time I was starting to really torque on it, my Dad walked by and quickly expressed his concern. After explaining the situation and repositioning my foot on the tire for a little more leverage, it popped loose.

FYI, mine did not have the gasket.
 
If you search the archives you'll find that this question comes up regularly. I think all the post-Jubilee four cylinder tractors (hundred series, x01 series, thousand series) use the same plug. A pipe wrench is your best bet. You might be able to get it loose with a sharp cold chisel, as well.
 
Well, I have been unsuccessful in getting the oil drain plug loose. The 48" pipe wrench just chewed the square area on the plug to oblivion. The penetrating oil just can't migrate upward into the treads enough.

I bought an oil pan gasket and even found a used oil pan off of an 801 diesel for $20 in case there is something wrong with mine. Yes, the part number is the same for the Jubilee 134 and the 801 diesel 172. While I have the oil pan off is there anything I should do or check? Crank bearing journal clearances with plastigage? Oil pump clearances? Suggestions are welcome.

Thanks,
Billy
 

I helped a guy that was turning the wrong way because he was laying on his back upside down and got confused.

Had to grind the plug square then use a 24" pipe wrench on it to get it off, but it came off pretty easy -- once it was turned the correct direction...
 
I surely wouldn't pull the pan to repalce a plug.

what type of pipe wrench did you use.. if you had flats on the plug.. the plug center should have broke out before the wrench slipped.. unless your wrench has alot of play.. or bad worn teeth.

tap it around with a chissle at this point... stay out of the pan.. just bit into the plug..

could also tack weld a nut to it.. or a flat bar too..

I could have told you penetrant oil would have been useless on an OIL DRAIN plug.. top is already imersed in oil.

At this point I'd also take a propane torch to it and heat the flange darm good then let cool.. if some fool used goop on it.. this should help it release..

Ok, I've got a question, ordered the 9N6730 Plug with screen aftermarket replacementfor the original 9N6727A3 me and my buddy finally got off. Only problem the threads are made higher up on the new plug which when tightened leave likes a 1/2 inch gap between the bottom of the pan to the plug. Any advice/solution?
