Re: [Amel Yacht Owners] Re: Onan Water Pump



I looked at your illustration. When water exits where you illustrated, the internal seal is leaking  and the pump has to be rebuilt. I had 2 water pumps and switched them when the impeller timetable called for a new impeller. I also had the rebuild kit for this pump, but never rebuilt it. I believe the bearing is pressed on with a hydraulic press. Hence, the reason that I had two pumps.

Is there anything complex about rebuilding the pump?  It looks like I would order parts 4 thru 12 and a simple matter of replacements.  

Can the shaft (part 1) be removed without worrying about orientation?  Would you also replace the Body (part 3)?

The local West Marine rep told me I'd probably have to go to Annapolis for the parts, since you're in Annapolis any suggestions?  I'm now in Lewes, DE on our way to Marthas V ineyard and Cape Cod.

Thanks for your replies!
