The process of just purchasing adapters was my original thought. I was advised that an adapter for NPT to ORB was not available. If they are available, all I would need is a short hose to run from working port on p40 valve to the existing tee currently used for the lift cylinders and a little modification for the tank/return line, adding a tee to connect the unused port. That sounds much too simple. I don't have any leaks on my hydraulics hoses, cylinders or connections at all. It's just the old dearborn valve leaks internally. I searched for a rebuild kit on the valve but I think its obsolete. If anybody knows of a kit available, pls advise. I was advised that the valve internal clearances are most likely wore and a kit would not completely repair the drifting, or internal leakage....which makes sense. This post has been most helpful. I'll try to connect with a NAPA locally that has a service rep that has the knowledge to advise on adapters. JIC fittings doesn't work with NPT threads, do they?

But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
