EZ Out? You're going to need to replace the plug anyways and if you crack it using the EZ out you'll be stuck drilling and tapping anyways.

 

Remove one hose and crank engine over with the spark plug disconnected. The pump will drain the system.

 

For clarification, you are referring to the plug on the TCV?

Hi on my 444...the drain plug allen head is rounded and looks to be rusted in. It seems to be threaded all the way in beyond flush

 

If you have the rear hydraulic PTO you can drain it out using that. Otherwise you are looking at a range of options for removing the plug such as the ones listed above. You might think about just looking on Ebay for awhile for a decent used TCV. I've seen some go fairly cheaply and they are pretty much compatible across a 30 year span.

 

yes tcv, thanks for all the input guys!!

 

Just wondering, are you just looking to change the oil? If so, cracking a line as indicated works well,

If you're looking at rebuilding the valve, I think I would weld an allen wrench onto it, using an allen wrench that fits an impact driver, "note its not an impact wrench" The impact driver I use for really tough jobs, is the type you hold in your hand, apply a bit of rotation pressure onto the wrench, and then you smack the end of the wrench with a hammer. The impact wrench is designed so that when you smack it, it gives a hard torque to whatever direction you're torquing it. I've gotten many bolts out that were stubborn like this,, A couple of weeks ago, I was taking a spare TCV apart,, for "overhaul" and that's the only way I could get that puppy out of there.

 

Always remember to " tighten " pipe plugs and pipe thread first to break them loose before trying to remove them.

 

Here's a thought, how about just welding in an old allen wrench or some hex stock? While it's still hot 'wick' some beeswax in... It may be your lucky day!

If it isn't completely rounded try a torx bit of equal size. You'll be buying a new plug anyway so you can fit it to the new one. You may have to tap the torx bit in but that will probably unsieze the plug.
good luck

I replaced mine with a square head pipe plug .No more worries with rounded off hex plug and how to get them out.

 

I would soak the plug with Parts Buster for a couple of days, and then hammer in a cold-chisel & try to twist it out. Sears has a fairly cheap set of chisels with some smaller sizes, and the tools have a square shank so you can get wrench on them. Heat might help as well.

 

me too lol

 

thanks guys ,got it out bought a new good quality hex socket,hammered it in and soaked plug for a few days and it went. Thanks again for all the great ideas. Replaced with square head plug.
