I have never taken a hydraulic backstay adjuster apart so have no firsthand knowledge of whether an adjuster is similar to a tractor hydraulic system or not. Surely the principle is the same. All I can go by is what I am told by marina repair technicians that I trust. The guys at Toressen Marine, who I and many others have a high level of trust in, told me that an adjuster should not be repaired by an ordinary hydraulics repair shop. They are not the same. They explained that, during training of technicians, after about the 6th rebuild, they trainees get it right. They had my adjuster for a week and could not get the proper seal kit from NavTec anymore, so gave it back. A tractor guy would have put off the shelf seals in that weren't designed for the unit and you get what you get.
So, FWIW, as I commented before, be careful where you save money. This is an important and expensive piece of hardware.

They are not all that different than anyone else’s hydraulics. Joe Della Barba Coquina
