I took off both my raw water pumps so I can change the impellers for next season. I have a silverton 31 c with twin chrysler 318s. the pump in question is a sherwood G7B. I removed the impeller, and upon inspecting the bearing/shaft housing, it seemed a little dirty around the seal, also there is an audible click when spinning the pulley. It still spins freely, but I don't like the click. I would like to replace the bearing(s) and seal. I'm curious if anyone has broken down this model pump before. I would assume that the pulley has to be removed to access the snap rings that hold the bearings in place (I could be wrong). There doesn't seem to be an obvious way to remove the pulley, other than having it pressed off. is this the way this needs to be done? I have rebuild Jabsco raw water pumps before, and the pulley on the ones I've done have a keyway, a set screw, and a thrust pin to hold the pulley on. I will say that the Sherwood pulley has a circumferential groove around the hub, that looks like its there for a puller. Just wondering if anyone has done it before.
Thanks
