Capen" Subject: Re: RV-List: spark plugs and cooling baffles I have Vans baffle kit interfacing to a SJ plenum. I put the socket on the plug - then put the extension on the socket. My plenum sits low enough for this to work. It wouldn't work with the extension already on the socket. Ralph ----- Original Message ----- From: thomas sargent To: rv-list Sent: Saturday, January 02, 2010 5:51 PM Subject: RV-List: spark plugs and cooling baffles I just tried to put plugs in my engine (IO-360-B2B) today and found that the cooling baffles make it impossible to get a deep socket on the aft, top plugs (on 3 and 4). Actually, I can get the socket on OK, there just isn't room between the socket and the cooling baffle to get the ratchet wrench or even just a simple breaker bar on the socket. Now, I don't have a real aircraft spark plug socket, just a 7/8" Home Depot socket, so maybe the real thing is a bit shorter? I should mention that since I made a cooling plenum for my engine, my baffles are 1 or 1.5 inches shorter than they would be without the plenum. So, there's no problem on cyl. 1 and 2. Every one must run into this same problem. Will I have to hack an access hole in the baffles to get a socket extension in there? Or will ordering a spark plug socket from Aircraft Spruce solve my problem? Gee, I thought putting in the plugs would be easy. -- Tom Sargent, RV-6A final assembly. ________________________________ Message 2 _____________________________________ Time: 12:42:37 PM PST US Subject: Re: RV-List: spark plugs and cooling baffles From: Dan Bergeron Tom: I have an RV-7A but the RV-6 should be the same. You will have to cut an access hole in the baffle in order to get into the socket with an extension. The hole then gets covered over with a piece of .032 aluminum, secured with a nutplate and 8-32 screw. Keep at it - it took my wife and me 6 1/2 years, but it's well worth it; these are incredible flying machines.
