  • How Do You Remove the Center of a 5/8" Spark Plug?

    I need to make a grease fitting adaptor to a 14mm spark plug, so I can hopefully use a grease gun to push a stuck piston in a Power Products engine.
    It was easy to snap the upper part of the plug off, but I can't even chip the rest of it inside the metal body.
    I bought two of these adaptors at AutoZone for just under $4, but still would like to knock out the centers of a couple of old 5/8" plugs.

    SPARK PLUG NON-FOULER 14mm with copper washer... stop plug from fouling!!

    Here's the link to one on ebay.

    Tom i usually screw the plug into an old head and then punch the center through. Wear googles as the porcelain can splinter and get into your eyes

      A few years ago I was using my 20 ton press to install an original impellor onto a new stainless water pump shaft, and that thing exploded, sending pieces all over the garage. From not on I'll buy the shaft with the new impellor installed.

        OK, the spark plug has a 14mm x 1.25 thread, and after doing some ebay research I found that thread is also used on some German wheel lug bolts, some bicycle pedals, some wheel studs, and some oil pan drain plugs. I just ordered 4 of these magnetic drain plugs, so I should be set for my projects, but I still want to remove a few centers from the spark plugs. Hate to get beat by a spark plug, so I might try the press.

          Spark plug continuity
          by Farmputzer
          If I continuity check from the screw cap to the electrode on a 3X spark plug, should there be any resistance, or at most very low resistance?

          Ran across this, for me really explains things and also shows examples of plug reads.

          Spark plug suggestion?
          by carolinamudwalker
          I have been running TT-10 spark plugs for 2000 miles on this trip and the porcelain is white as snow. Can someone suggest another plug? I am confused and thought I needed a hotter plug?

          Firestone S-80-CF plug gap?
          by psavello
          My restored 1928 Model A Roadster came with Firestone S-80-CF spark plugs. I cannot find through multiple searches the recommended gap for this plug. Any help/reference would be greatly appreciated. Also, does anybody know the difference between this Firestone plug and the Champion 3X plug (other than cost!)?

          Where can I buy a compression tester and what product brand will fit a Model A engine? Are thread adapters also needed to fit the plug hole?
