not even sure if this is the problem Larry, it's a part on a new/old machine I just had shipped up from good 'ol Alabamia, sposed to make a motor move on a piston and not working...but when and if I get it working it will be the mother of all drilling machines...2 horse 3 phase 240 motors on it
The part I got a question on was originally made in the 50's.....and they still make it today too!
