Happijac new vs old?
I have electric Happijacs, possibly 4600 (numbers are illegible) that are complaining. I could: 1) remove, clean and relube 2) replace the legs with 4220 or 4820 legs 3) replace the whole set...

A couple of years ago, I needed to order a replacement for one of my old jacks that had frozen with broken parts. A tech rep at Tweety's had all the information on recommended replacements and compatibility of parts. I suggest you give a call and see if they can help.
