To make the tool, you need:
- a 5/16"-24 piece of all-thread , 3" long
- a 5/16"-24 coupler nut
- a large washer, 2-1/2" OD, 5/16" ID, 3/16" thick.
On one end of the all-thread, machine or file a couple of flats 180 degrees apart to put a wrench on. Chase the threads around the flats with the nut. Permanently attach the coupler nut to the other end of the all-thread, screwing the coupler nut about half way on. I used Loctite 272 retaining compound to lock the pieces together, one could also drill and pin them together, or braze them.
Usage is similar to the first version of the extractor. Install the coupler nut on to the grease cap, slip the large washer on, and install and run the 5/16" nut down. Continue to tighten the nut against the washer with a wrench until the grease cap is free. Use a small adjustable wrench on the flats of the all-thread to keep the all-thread from rotating, if required.
