Ok so the model on the data plate of the pump says 9201, and on the side of the pump case is has the number 5515. From looking at other stuff online I think this is a quincy 310 pump, is that correct? It has a leak from the seal where the crankshaft comes out, Looks like a very slow, years to build up kind of leak. Am I correct on the model of this pump? I am wanting to just go ahead and rebuild it real fast while I take it apart to give it a sweet paint job. I also need a new gasket for the valve on top.
The serial number says 310-21, I am beginning to think that means its a 310 pump, ROC (record of change) 21.
