Stuck drain plug

[Mike'sHorseBarn 2,998]

So I have a stripped drain plug on a raider 12. I guarantee the fluid was never checked because I had to heat the dipstick to get it out, it was so pitted and rusty! So the drainplug I heated and got an impact on and no go. So I got a big breaker bar on it and that's when it stripped. The trans is full of what looks like peanut butter and it leaks out the axles and brake shaft. Thoughts on my next move?

Possibly drilling a hole thru and using a "spiral screw extractor"?

That transmission should have a side rear drain plug at the left rear. 

May have an extension. 

 

If you can remove that then raise the front of the tractor you'll be able to get most of the nasty fluid out.

It does, I like that idea! I have a chain hoist I can take the hood and raise the front. I thought about using my homemade fluid extractor too.

Whatever you can do to get the most gunk out is effective.  

Empty. Fill. Run it.

It'll flush.

I was gonna run fuel oil through a few times to try and flush it out.

Manual transmission right?

 

K1. #2 fuel oil. Diesel. Any of them would work.

You could tap a torx bit into that drain plug, or weld a nut to it and try backing it out.  Sometimes with pipe fittings, you can’t loosen it but you can still tighten it.  If you can get it to rotate right first, then it’ll spin left.

I had also stripped the drain plug using an impact wrench.  Tried using a spiral bolt extractor. No luck.  Then I used a left hand drill bit and inadvertently drilled all the way through—oil started dripping!  From there I simplify drilled the rest of the plug body out and tapped new threads. Carefully flushed tranny several times and used a round magnet to trap any steel filings I may have created.  Installed a bolt with a head and gasket.  I can put a box end wrench on in the future.  Downside is the Bolt head protrudes below the transmission housing.  It is not flush like the original, but I don’t have any implements that it interferes with.

If I had a welder handy, welding a nut to the plug would have saved me a lot of grief.  A small flux welder is now on my list of next purchases.

Unfortunately, impacts on hex plugs will hammer out the flats and you end up in the above situation. Do more harm then good.

I worked as a bush mechanic in the mining business for years and have taken out all sizes of stuck hex plugs and cap screws. 

The trick is to put constant tension on the plug or bolt and strike the head of the spud. The inward shock will help loosen without compromising the hex flats. 

The heat is a good idea. And there were times I would hit the plug or bolt head with a hammer before I tried to loosen with a key. 

Below is an example of how I took out stuck coil hex cap screws on a kohler block. They would not budge with just the Alan socket, so much the key was starting to twist. I held tension on the ratchet and rapped on the ratchet head to shock the bolt. The vid would not load for some reason.

Small example but you get the idea. And these are not what a guy wants to snap or strip

Like @JoeM says, shocking threads is always a help!  I have an impact driver that helps break stuff loose as well.  In a pinch before, I’ve found a big box end wrench fits a screwdriver handle well.  Then tap the screwdriver in the same fashion while turning the wrench.  Lots of ways to skin this cat.

@ MIKE,S HORSE BARN , think the solid bottoming out of any , removal , extractor is vital , also using 6 point related movement ,socket , breaker bar , when its a very solid hook up , a careful  pull start on the bar , usually does it , another thing , on that flush . is road time , not just a quick lawn drive , like hi mileage , atf fluid , as a cleaner / flusher , fuel oil is also good , also use , back and forth , for a distance , to increase the lube spray / flush , like lucas climbing gear oil , new shift boot , lubricated inside the  bottom of boot to enhance slide , tye wrap that boot ABOVE THE BOOT  to metal shaft , letting boot move , yet stay in place , done this to my 3 units , no issues , pete

I pounded in a sacrificial torx bit last one I had and got lucky it popped loose.

That's one problem with water being heavier than oil. It sinks to the bottom and goes right to the drain plug. Let it sit for awhile and you have a nice "rust weld". If all else fails, drill it out as close to the edge as possible, then re-tap it. Replace the plug using anti-seize.

Heat it with a torch to break the rust. do this outside.  Then tap a sacrificial torx into it.

I'm assuming by responsibly you don't mean burn it in a brush fire?  I'll show myself out now......
