It is made of metal.
I have an old Hein-Werner O'Boy 1 1/2 ton floor jack that has a few years on it. I started tearing it down to clean it up and a couple of the springs balls and seals from the hydraulics shot across the room. I found all the arrant parts, but failed to remember the order they ejected. I am trying to figure out how to get it back together again.
Hein-Wenner doesn't seem to have a web site and I haven't found any exploded diagrams of the jack. The kit for the jack is a little spendy and doesn't say if the instructions are included (I doubt it). Does anyone have have a copy of an exploded diagram or know where I can get one?
TIA
