Hi all, I purchased a couple of Hein Werner WS jacks some time ago and rebuilt them. The rebuild went fine, no issues. The jacks dont leak and they go up and down just fine. Here's the issue. Unless I put a plier to the release valve knob, I cant get these things to hold loads up and they slowly creep down. The model WS has a pin style release valve with some sort of seat inside the body. Is the sea replaceable? Do I need to lap the pin and the seat somehow? Or is there something I am missing. I love these old jacks. Didn't even bother painting them as the platina is great. Hoping someone can help me keep these two jacks going.
Thanks!
Thanks!
