are parts availble for shop crane? Hydraulic ram plunger o rings has split....need part?
What is the crane make and model? If you don't have the model of the crane you can stop by almost any hydraulic/hose shop, they should be able to match up the packings.
may have one, or try a tractor supply shop in your area. You can try matching the ring at an auto parts store that has balk parts behind the counter.
You okorder / and buy a whole new jack. I replace one with Northern about two years ago. I got one that pumps on the up, and down stroke. Works better than the original!
