My Heil dump body, probably built 1975 has two stage hydraulic cylinders. The part number is AID or ALD 2039-1
In dumped position it does not leak & would stay up months. In down position it leaks out the breather. I'm of the belief the pressure seals the piston, but when pressure is released, it seeps past the piston.
Hydraulic repair shops are understaffed, overloaded with work. The wait seems forever. Most promising is a shop in next state, a one man shop. He makes promised of "a few weeks turnaround". I think I can handle the rebuild, but a seal kit is at best a maybe.
I googled it, Found a company Allegany York, they offer a kit for Heil cylinders. Surely, there is more than one variety cylinder for Heil dump bodies? Could it be? The seal kit RH-K272-4893
