Primarily Petroliana Shop Talk Forums Thread Like Summary - Wayne 276 pump stuck

Recently acquired a Wayne 276 and I have no experience with previsible pumps. Forgive my terminology if incorrect, but the plunger is stuck so I cannot crank the pump. I poured a can of seafoam down the fuel outlet pipe but really do not have an understanding of how it works so i'm not sure if it will help. I plan on cleaning the pump up and it will be an outside display so I really dont want to completely disassemble that part of the pump. Any ideas about getting it freed up are appreciated.

On these old units, the pump is similar to an old boat bailing tube. The gear system is attached to a simple stroking rod which has a pump ring at the end. The pump plate has leather sweeps attached to cause suction....bringing gas up from the tank. On the down stroke, there is a way to release pressure in the same area. The rod goes up and down inside a brass cylinder. This is a very basic machine. If you don't want to take it apart, try some automatic transmission fluid? It might work? Let it soak a while. There have been times, when I have restored these old pumps and no matter how I tried to get them to move.......I have had to tear them down to accomplish the results needed.

I believe you are going to have to disconnect the plunger rod and handle. Also separate the gear case from the plunger. You probably have two or three location where this mechanism is bound up.
I'm thinking that once the rod has been raised during the pumping of gasoline there is something about pressing the handle shaft towards the gear case and that allows the plunger to go back down into the cylinder to start over. Sorry, It's been awhile since I restored mine.
