JBASCO IMPELLER REPLACEMENT?

Postby kwoffa » Wed May 09, 2018 7:45 pm

Hi Chaps..

My Impeller is in bits!!...i have ordered two new ones so no problem with replacement except i cannot remove whats left,its the middle bit that sits on the shaft..i can see a very small pin? there is no slot in the shaft so it dosnt just push on or pull off ! does anyone know how to remove this...is it the pin thats stopping it ? if it is a pin ? on the cap it says 1/4-400 the pump is bolted to a 100e engine now off...its the last thing stopping me going in the water...it may have never been changed..i really dont know...TIA ..

Have you got all the bits of the failed impeller? If not they may lodged in your cooling system.

Most if not all the bits was jamed in the pump ! causing a hose to come off !! My new impellers came very quickly..and have been fitted..so hopefully when i put a hose in tomorrow and fire her up if there is any loose bits they will flush out..i will run the engine up to temp..and keep my eye on the temp..which will be a good test,my old impeller was quite brittle....so shouldnt cause any problems...Tuesday misty is going into the water for the first time in years ! so a big day coming up ! :woo:
