I'd guess its rooted because someone run it without coolant
(sorry Mick couldnt help meself)

Just pulled the water pump off, there is a shaft that drives that impeller and it goes into the motor somewhere and it's broken, how, why? Fucked if I know, now a matter of sussing out if it's worth fixing or the bike goes to Vic bike wreckers as a piece of shit and I either a) become a cager or b) more likely, loook to get a loan for a bike..

Pink ribbon will have to go without me along with a shitload of other bike rides for a while I reckon, damn!!!

Mick - I think you may find that impeller shaft breakages are not that uncommon at all. Remember, that little shaft has to pump through thousands of litres of coolant each week ( assuming you ride every day).

Not sure on the exact figure, although I am sure there is an anorak out there who could work it out, but assuming it takes 1 minute to pump 8 litres of coolant through the system, then 1 hour riding would equal 480 litres pumped...............do that 5 days per week, and you are looking at almost 2,500 litres per week...... ( and thats using conservative estimates of pump capacity...)

Replacing the impeller shaft is a pain in the arse, but not the end of your bike, thats for sure. Chin up mate, it could have been heaps worse.

stop being a bloody accountant and tell him how to fix the bloody thing....

It could?? Well yeah I guess it could, dunno about MUCH worse but indeed could be worse. Quote for repair is around $1500, have to take the motor out, split it, replace shaft and indeed water pupmp, then put it all back together and back in the bike.

Will be needing a veritable shitload of gaskets and frankly it's not worth it so time to go bike hunting.

This will become a project, hopefully not as big a project as Tapes

I hear the 14's a nice tourer.

I think a goldwing would be more fitting for Mick, he could sleep and ride at the same time!

mate..sell the zzr off or parts..well what ever parts are usable...

Quite your bitchin, fix it and go for a ride you old poof
Some would kill to have a broken bike being the only thing stopping us from riding ...

We offered to fix it for him, I was all ready to go and pick it up. I am no good at fixing bikes but I could have broken it more for him Tones was happy to do the job for him

Well I had a bid on an older model ZZR600 on ebay but been outbid so there goes that idea

So what's exactly broken? the shaft that drives the impeller on the pump? or whatever the heck it plugs into within the motor?

I took the waterpump off my old gpx recently and the shaft went all the way into the motor, i gather the fugger broke and has fallen into the sump somewhere?

Mike, yeah that's exactly what's worng wit it, will need another wter pump too.

That's a bit of bad luck Mick.

Mine went earlier in the year, first I knew about it was when it leaked oil all over the footpath at work. When I pulled it off to replace the o-ring sealing the outside world off from the engine oil, I found the bearings in the water pump had shat themselves. I'm guessing if I hadn't found it when I did then the bearing contents would have found themselves inside the engine with disastrous results.

Anyway, I got a 2000 model pump from a wrecker and used the internals with my casing (the 2000 has a manifold heater fitting). Seems ok...so far .
