I've dealt with a couple of actuators that were full of likely what was air and gear oil mixed into a greenish goo. Patience and some brake cleaner finally got it cleaned out enough to start working again. I would strongly caution against bench testing the actuator. The one I did that to immediately blew the air seal bellows never to function properly again.I have done that, air comes through continuously, but when the line is connected it behaves as if clamped like there is no space for the air to pump to, and the locker is not actuating, air comes out continuously. I have not seen failure of air getting into the locker actuator being a problem in any posts, so didn't know if anyone had experienced them "clogging" or had a solution for that. Given lack of production of the actuator it looks like I will likely have to transition to an E locker or ARB, but if the original was salvageable I would prefer that. Just looking to see if anyone had run into this before.
You are correct on them no longer being available. I sent the last one NIB that I had to someone I trusted who promised he could easily replace it. I cautioned him to verify that to be true. He assured me it was possible, repeatedly. 3 years later, I'm still waiting. To be fair, I knew he wouldn't be able to.
