Kawasaki Water Pump Removal
I'm looking to remove the water pump impeller from a z1000 based engine.
It's similar to a ZX9r and zx12r where the impeller is bolted to a short shaft sticking out of the engine that also drives the oil pump behind a
seal.
My thinking is that I can unbolt the impeller, leave the outer water pump cover off and just let the small shaft stay uncovered and rotate as it
measures around just 10mm. In future I could potentially use it to drive an oil scavenge pump of I have to either dry sump it. Am also turbo charging
it but likely won't need a turbo scavenge pump.
Either that or I can trim the shaft and fit a plug. Could use the hole for a turbo/breather return but I think with the oil pump being so close it
would end up recirculating the hot/unfiltered oil from these returns.

I presume you're fitting an electric pump instead?
Font know the engine but from looking at a couple of videos (not exactly clear) it looks like you could do as you plan. Is there a reason you want the
shaft exposed and not put the cover back?

I could put the outer cover back on to protect the shaft but I would redo the cooling system and could be impractical to route it just to run coolant
through the pump casing.
I have a Davies Craig pump hence why I'm looking to remove the impeller.
I did buy a used Kawasaki heat exchanger as other engines in the family use one thinking it would be cheap cooling but I've since rethought it
and will go electric pump for coolant and an external oil cooler for the oil.
