I have Tempest Plugs in my Lycoming O-145-b2 (REM37BY, 5/8” plugs, 18mm threads).

But I'm having an awful time finding the right socket for these plugs!

Aircraft Spruce has the right size, but has this note:

T-557 3/8” drive without magnet PN 12-00710
T-558 1/2” drive without magnet PN 12-00712

Not for use on Tempest spark plugs.

There's not much room so I need a fairly thin-walled socket.

Anyone else solve this problem or at least point me to the right socket?

Thanks!!

Dan,
I use a Craftsman 6pt. deep socket. Some of the others don't broach the socket deep enough, even the expensive ones. Champion sells one but I found the Craftsman is about as thin as they get. Some of the Cubs and little Lycomings need the thin sockets to get through the eyebrows.

Great info -- I'll stop by Sears tomorrow. Thanks!!

Dan,
Take a plug with you.

I don't have any old ones and the only Tempest plugs I have are in the airplane (moved 200 miles from the A& that worked on my airplane)

Dan,
I guess just make sure the socket is fully broached.
