Has anyone used one of these to extract transaxle oil?

The PO of my 911 bodged the 915 drain plug and I can't remove it to change tranny oil. I've been removing the case cover to drain/change the oil, but the gasket is getting a little bit rough, and I need to find a way to pump the oil out through the fill plug hole.

Thanks, any suggestions are appreciated!

It looks doable. I'd do it without any kind of tip on the hose.

How on earth did they bugger a 1/2" drive plug? insert ratchet, turn. How hard is that?

Looks almost like the pela oil extracator I use for my TDI and the oil tank in the Targa.

i have heard of this happening before . My buddy did it to his 944 , that was a 17mm socket. We fixed it by tack welding the head of a 17mm bolt into it and welding a nut on the other end of the bolt then it came out. Not sure if it was the tool we made or the application of heat but it can be done.

I think they didn't have the right sized allen tool, and rounded it out. When I first bought the car, I had to fix a lot of things like that. Many of the bolts were overtightened as well. At least whoever did the suspension was very good. I found that the t-bars were in great shape. They came out without any hassle.

I might have to wait until the tranny gets a full rebuild before I can get the drain plug out. I tried a nipple extractor, but the sides of the drain plug tore loose, and now there is nothing left to grab. I think I'll buy the vacuum fluid extractor if it comes with a 1/4" hose. I think that 90wt hypoid may need a large tube.

I would try Ice's suggestion of welding in something and then taking out the drain that way.

time for "high heat"?

Here's a pic of the drain plug. It's not a hex plug. The walls are very thin, and when it was rounded and probably overtightened, the thing split apart. When I tried the nipple extractor, the walls completely gave way.

I'm afraid that if I try a welder, I may damage the threads and not be able to get this replacement plug in there. I also think the plug must have been really tightened.

This is the 17mm allen key that I bought from Sears many years ago for the 911SC.

Take it to a good 911 mechanic who has probably freed many of these frozen plugs in all manner of disfiguration during his career. Then, do yourself a favor and buy the Pelican tool designed for this plug and you will never have another problem with it. The first time I tried to remove it I used the 17mm hex socket from my set and it wouldn't work. 2nd time I bought the Pelican tool and it came right out. Good luck.

Thanks Chris. I looked on Pelican, and all I saw was this tool that looks like a 17mm allen wrench.

That is it. The edges are cut much better than your average hex key socket set piece. The thing only takes 20 ft-lbs or something but even at that low torque the one from my set was just floating around in there. Cue the right tool and it came right out.

I realize the current plug in your tranny is beyond help but I'm talking about for future use with the new plug you will replace it with.

rusnak

oh, I get it. Thanks! BTW I don't buy tools from Harbor Freight. The one I pictured is a Sears Craftman, and their steel is much better than some. I have a hardened set from Lisle Tool, but theirs only goes up to 10mm. For 12mm, and 17mm I had to go buy a Sears tool.

I've had great luck is your situation by welding a cheap allen wrench to the plug, letting it cool, and then backing it out.

Install a new plug and you're good to go,.. .
