spark plug removal

Wed Jun 27, 2012 6:03 pm

Hi, In spite of sounding stupid, I am going to ask anyway... I have a Farmall Super A and I recently was going to change the spark plugs. My problem is that it has the recommended Autolite 3116 but they are threaded in so far that I can't get on the hex part to facilitate removal. I managed to get a pair of needle nose pliers in the tiny gap and got 3 out but cannot get the fourth loose. Is there a trick or special tool to get them out. There seems to be no room outside the hex for a tool. Any suggestions or advice will be greatly appreciated.....Thanks

Have you tried a thin wall deep socket?

A standard deep well socket. There is just no clearance. I thought someone had the incorrect plugs in until I checked it out. I will just keep trying and if all else fails, break it and try an easy -out or something. Thanks Anyways :-)

I run Champions, don't know if that matters, but 7/8 deep well fits them all.

I've had no problems removing the plugs from my Super C (same engine) with a standard deep well socket. Have you blown all the dirt and debris out of the plug well?

The area around the plugs on that engine is just the rough casting and there is some variation from one engine to another. Some of them get really tight and need a thin wall socket. When the tractors first came out, the stamped steel plug sockets were common. They were pretty thin. A minute or so with a die grinder or a Dremel would probably be a worthwhile fix.

I have been running bosh plugs in both my cub and 130. I've had better life with them and they have a reduced hex size so you use a smaller socket and have more clearance.
