Re: Elto Sportster Not Pumping Water

Those ‘wobbler’ type pumps are among the simplest designs around, there’s not much to prevent them from working, other than excessive clearances – as others have noted.

I don’t mean to be insulting, but are you sure the little drive pin #550082 is in place? The pin is about 1/4″ long, and inserts into the prop shaft. The eccentric #550085 then slides over the prop shaft, and has a machined groove to accept the drive pin. Finally, the rubber rotor (aka “wobbler”) #550040 is fitted over the eccentric.

No pin = no eccentric rotation = no water flow. And they’re so easy to lose or just overlook.. Also, a missing gasket or intermediate plate will shut things down, too.

Thanks for the tip, because I was wondering where that extra pin came from…, but unfortunately that is only one of the problems because it still won’t pump water. What exactly do you mean by intermediate plate, though? Any further elaboration and ideas would be greatly appreciated.
