Sherwood R10870G assembly

PMF1984 said:

I recently did a major pump rebuild of my raw water pump, Sherwood R10870G. This should be good for 4 years. After 125 hours of use the main bearing crapped out - as in disintegrated.

Either: 1-The bearing was defective, or 2-I reassembled the pump incorrectly.

Given my mechanical abilities, I can't rule out #2. The Service Bulletin says "Note how the seal and seat assembly are arranged so they can be properly reassembled." Perhaps I did not "note" the arrangement correctly.

Does anyone have a picture of how the internal seals fit on the shaft? I have a color schematic on the "R Series Technical Guide" but it is a little short on the critical details.

Buy the parts from Depco Pump and they can usually help you if Sherwood can't. Or treat yourself to an early Christmas and have them rebuild it.

I enlarged this view of a technical drawing of your pump that appears to illustrate the relationship of the seal to the seat assembly. Good luck

Thanks for the tip about Depco Pumps. Their pump catalogs are quite the resource. For parts I'm quite wedded to Niemiec Marine in New Bedford. There are close by and very reasonably priced.
