0TreeLemur Posted July 7, 2020 Report Posted July 7, 2020 My hangar neighbor has a 7/8" hollow, thin walled, deep socket like tube that is about 4" long. It isn't really a socket because you can't put a ratchet on it. Rather you put another 7/8" socket or open end wrench on the top. It is just the right size for removing the top plugs on an O-360 with the doghouse. This was made by Kobalt. Lowes says that they no longer offer this item. I've looked all over for a socket that is long enough to work on spark plugs but haven't found one yet. Anybody got an extra one of these they would part with? The Kobalt P/N is 49887. Apparently they have been out of production for some time. No joy on ebay or Amazon. Here's a photo. The top is about at the top of the photo. Thanks -Fred Quote
Hank Posted July 7, 2020 Report Posted July 7, 2020 (edited) I bought a spark plug socket from Aircraft Spruce several years ago, it works well for my C. Fits my ratchet and my torque wrench just fine. Part of the benefit of visiting Spruce, just tell the nice man what you want . . . . They're just 30 Mooney minutes away.

David Lloyd Posted July 7, 2020 Report Posted July 7, 2020 I had an old 7/8" very deep Craftsman socket for years. With the tight baffles on the RV (maybe Mooney too) it was long enough to be a problem getting past the baffle on the top plugs. One day I realized that it was so long, an inch could be cut off making it fit better. Measured carefully, worked perfect. A month later got some new Tempest plugs. My favorite socket would not reach the hex on the plug. Could not find a socket deep enough for the Tempest plugs. At Sun&Fun, the Tempest rep told me they still had a bunch of long sockets, send him an email. I did and got an appropriate socket the next week, free of charge. Had the Unison name imprinted, the plug mfgr. that Tempest bought. It does have wrench flats in addition to the ratchet drive. 1 Quote

My neighbor's tool is the only one that will reach. I'll take your lead and contact Tempest. Thanks! Quote
0TreeLemur Posted July 7, 2020 Author Report Posted July 7, 2020 One thing I didn't mention about the Kobalt tool shown in the first picture is that it is light weight. It isn't like a 1.5 lb socket, more like half that. Lighter weight gives one the ability to travel with more tools. Of the four options given by @N201MKTurbo, only one will work with Tempest plugs on an O-360 https://www.aircraftspruce.com/catalog/topages/ATSmagSocket.php Another thing is that the cooling fins on the O-360 are close to the plug, so the max. tool dia. allowable is 1.18" Quote
0TreeLemur Posted July 7, 2020 Author Report Posted July 7, 2020 I found another photo showing what the top of the tool looks like. I think this thing is cool. 1 Quote
Yetti Posted July 8, 2020 Report Posted July 8, 2020 I went through this with the tempest plugs. Champion fit fine. It's either the Home depot socket or the Harbor Freight that fit. or maybe it was the Oxegen Sensor socket from HF. You can make others fit by drilling out the top or dremel tool. 1 Quote
Igor_U Posted July 8, 2020 Report Posted July 8, 2020 I never thought a spark plug socket was so difficult to find. I have one from Harbor Freight in my travel kit and is working fine with Tempest plugs (or Champs in the past). The other came from old socket kit (Mastercraft?) I have for years and I never had any problems. YMMV. I must admit Kobalt is looking good, though. 1 Quote
Jeph357 Posted July 9, 2020 Report Posted July 9, 2020 (edited) I use this with a wobble extention. The magnet is awesome! You know the saying about spark plugs, "Drop it once then drop it twice" https://www.aircraft-tool.com/shop/detail.aspx?id=ATS950 Edited July 9, 2020 by Jeph357 1 1 Quote

bradp Posted July 14, 2020 Report Posted July 14, 2020 I have a deep well craftsman that works perfectly even on my fine wires. I was a hardware store find. I can get a 1/2 torque on there just fine with the baffles in my J. Quote

It is well made, thin walled, and worked great for Champion plugs on my IO-360. I have a Cruz Tools kit on my dirt bike that is well made and thought out. The owner of Cruz Tools flies a Mooney (was it an E?). Met and chatted a bit (after I had his tool kit). Unfortunately, when I got Tempest plugs, it was too shallow since Tempest has the hex lower down. I got the Tempest socket from Aircraft Spruce. -dan Edited July 14, 2020 by Bolter typo 1 Quote

tony Posted July 29, 2020 Report Posted July 29, 2020 The tempest plugs are a bit longer than the champions. I think I got a socket from napa that worked out ok. Bring an old spark plug with you and see if they are deep enough Quote
