MG TD TF 1500 - Remove brass plug from TF branch pipe?

How can I remove the brass plug from my TF branch pipe? The branch pipe (AEF124) is for a late TF. I can't turn the plug. Don't want to destroy it.

Thanks for your advice,

Lonnie, try a heat gun on it's highest setting, try to get more direct heat on the pipe rather than plug, let it get good and hot, then a 6 point socket to remove, I think the plug is a Whitworth size?? PJ

Thanks Paul. I’ll try it. Yes - it has a WW head.

See if you can get your hands on a heat induction tool kit you can borrow....

Works great

If you heat the pipe you can also freeze the plug. A can of 'freeze spray' from a plumbing supply shop will work a treat on brass.

It is designed to freeze a plug of water in a pipe so you can cut it without figuring where the stop cock is.

Cheers.

Update ...

Nothing to update. Plug is still frozen in the pipe. Heat gun on the pipe and ice cube on the plug didn’t work. Hex head is starting to show abuse. I’ll try propane torch next.

Why remove it? Does it leak?

I will install an Arnolt heater. I want to use the later TF water outlet and pipe.

That would buzz out with a rattle gun
If you have a 1/2" drive socket that fits it take it down to your local tyre shop and get them to rattle it out--they might even have a wheelnut socket that size for the job-----

SUCCESS!!

I finally got the brass plug out of my TF AEG124 bypass pipe, so I'll be able to run the return line to my Arnolt heater.

William - I was holding off using an impact wrench until all hope was gone. Pretty sure that it would have rounded the brass hex head.

I tried heat and various penetration liquids with no luck. Yesterday, I heated with a torch. After no success with a 6-point wrench, I poured a 50-50 mix of Acetone and Liquid Wrench into the hot pipe and let it sit overnight. Didn't have any ATF to make Sandy's famous Acetone&ATF potient. Today, it moved, squeaked, and came out.

Not pretty inside. After I took the picture, I removed the shoulder of crud and cleaned the threads with a pick and brushes.

Next steps: Clean the threads with a 3/8" BSPP tap. Then find a 90-deg 3/8" BSPP to 5/8" hose with cutoff for the AEG123 outlet, and 45-deg 3/8" BSPP to 5/8" hose for this pipe. Any suggestions where to look?

Lonnie.

Thanks for the plug.
I think that the acetone did the trick by is ability to permeate all sorts of cavities and carrying the lubricant along with it.
Looks like you are doing a bang-up job. It is people like you that are keeping up MG world as is should be.

Lonnie. When you install your new fitting coat the threads with some Never-Seiize. It will prevent galling and make the piece easily removable in the future.
