Hi Mark,

The easiest way is to have someone apply pressure with the wrench and then take an aluminum rod and tap it smartly right on the edge of the screw a time or two. Comes out very time without fail. I have never had to heat or use cold. Then I don't put them back in so tight after the first time. Safety wire it when done. If you ever strip the old style Torx #40 screw then it can be removed two ways. One is grab the outside edges with a pair of small vise grips and the other is to use a Dremel tool with a cut off blade and slot the top so you can use a straight tip screwdriver on it.

Hi Roger

Thanks for that, I will give it a go. I have no intention of putting it back, I will fit a new one.

Cheers Mark

I have used the vise grip method with success on an old stripped torx plug, used a rod and hammer to give the head of the plug a good loosening smack. fitted a new hex head plug after .

Put the (new) plug in with a C & A gasket under -just like many oil tanks drain plug have - torque it as per drain plug & wire lock. Never too tight, never leaks.


Transforms a desperate annual misery into a really easy job. My tired & tested remedy for years.
Too many pilots avoid disturbing it to check through fear !

Mine twisted off the torx socket the first time I tried. I went flying and got the engine good and warm and immediately after landing I tried it again, and it came out easily.
