My Navtec hydraulic back stay adjuster started leaking/slipping a few years ago after ~ 17 yrs of reliable operation. In the farming area of eastern NC where I live, there are many hydraulic shops since just about every farm implement uses hydraulic pistons--often many on the same tractor.
All new seals, piston/sleeve polished, etc. more or less like new for ~ $260. Hydraulic technology is much broader than the relatively small but effective uses it is put to in sailing vessels! Sending what is a relatively standard piston back to Navtec ensures a high repair cost but not necessarily a better repair.
