Have a relic for farm use, problem is the boom vlv looses fluid like a screen door. Have previously purchased a used vlv, have rebuilt both the vlvs three or more times. No luck. Any suggestions besides cutting up for scrap?
Where does it leak fluid from? Might try repacking the boom cylinders. Might help.
Boom Valve, control block. They do not make them any more. Unable to find any after market part ether.
