The plastic gear on it is shagged though (cracked in multiple places), but much to my relief the existing one from the bike has a very new looking gear (but muffed impeller).
So I want to remove the gear off the shaft put the good one on and with the good impellor and reinstall it.
I see a size 10 socket on the impeller, would you just grip the other end of the shaft in a vice with wood blocks and twist the thing off? left or right hand threaded?
Cheers guys
