I just picked up a '79 Jeep CJ7 that has an old Meyer setup. Unfortunately, the previous owner completely covered the pump and motor unit with some type of undercoating so I can't identify it. There are also no operator's manuals. There is a lever on the pump that is actuated by a cable that leads into the cab. It is a manual angle plow and the lift arm does not electrically/hydraulically move right now; only by hand and with no resistance. I was told that the pump leaks and I'm sure there's little or no fluid left. I can't even see where the fluid-fill hole is. It probably needs seals at the least, but I don't know where to go for a service book or more information. Any help would be appreciated.
