Ok, here is my selection of water pumps to choose from for my rebuild; each one slightly more ugly than the next . the one in the middle 'looks' the best but it is worn right down at the end where it rotates in the bearing. The other two, aside from being corroded do have better bearing surfaces but in both cases the hard chrome(?) has worn through in patches and picked up a bit of bearing material. has anyone found a successful way of rebuilding these shafts, whether it be rechrome and grind or machine the ends and weld on a new sleeve, etc, or other method? Failing all that, does anyone have a good one that they would be interested in parting with?

The centre one.Clean the seal side up by polishing it.
Turn the cover bearing end down in a lathe, then make or get made a new phosphor bronze/nylon/whatever you choose bearing to suit. You could also clean the end up, weld it up and turn back to original size.
Easy if you have a lathe. If you don't, this is the perfect excuse to go buy one! They're fun!

If you buy an over-the-counter water seal from a bearing shop, they come in a kit with the seal shown in the photos from my post describing the tool dimensions.
They also come with the a new seal "face"- usually bright white in colour. It's the bit that the spring loaded seal rubs against as it spins. When buying from Suzuki, I've only ever got the metal bodied seal (with spring etc).
Until recently, I didn't know that the seal "Face" on the "wheel" like component on the RE5 shaft is actually removable. It's the side of the "wheel" that is opposite the impeller. You can prise it out and fit a brand newy from your replacement kit, no polishing required.

That's interesting to know, Wayne. The concern I had with welding the shaft to build it up would be that the heat would potentially destroy that face, but if it is removable and replacements available then that makes the job easier. In saying that, is the rest of the face holder (for want of a better description) all metal / heat resistant? For some reason I had in my mind that it was composite or carbon? I was about to order a replacement seal from 'GTReimer', but I suspect his dont come with that extra seal face? I don't suppose you have the common part number for the locally available ones?

Andy, I've gone through every box of RE5 bits I have (and trust me, there's plenty) and unfortunately could neither find a new seal set or old waterpump shaft.
I've given away a handful of seal sets over the last couple of years to people needing one in a hurry. Time to go back and buy some more.
I only know that when I've turned up with an original seal at the bearing shop they've disappeared out the back to bring me a new one and it's always come in a baggy which also contained the white sealing face. Try your local ?
As for the material of the wheel-like holder, I'm sure Jess would know the answer. I thought it was metal but can't say I ever checked that closely.

I spent ages in seal shops here in Perth and none could supply a seal of the right size. Yes they had the new ceramic seal face in its rubber holder but none of the seals fitted over the shafts. In the end I bought a couple from Jess- which I should have done in the first place. I just wanted it right now!

Yes, I recall now the problems you were having with the shaft diameter. I have seen the version of the metal seal which is identical in every way except it has a too small inner diameter for the RE5 shaft. For anybody else's interest, this is the ceramic seal that is fitted into the "wheel" on the waterpump shaft. Unless you look closely, it all looks like the one piece but in fact you can pop this part out of the shaft "wheel" housing and fit a new one.

Thanks for having a look, Wayne. I took to my grottiest looking shaft with a pick and popped the rubbing face right out! It's design is pretty simple, yet quite clever. Until you pointed this out I thought it was all manufactured as a one piece unit. The outer housing of the "wheel" appears to be steel so heat from welding shouldn't pose a problem.

Hi Neil, picking the steel up this week to have a go at making the shaft, seal kits are available off the shelf so I'll get one and make sure the ceramic seals fit the new pump shafts, I have also extracted the graphite bush from the pump side cover and will be replicating that in phosphor bronze with a bit of luck might have something for you next week.

Thanks Stuart, I'm sure there will be more than a few people here watching with interest?. I bought a new pump seal the other day from GTReiner but it didn't come with a new rubbing face to go in the shaft 'wheel'. I know Wayne mentioned that he had in the past sourced replacement seals locally over the counter which came complete with a new bit for the wheel but my local seal supplier couldn't help.

Can the complete seal (impeller and housing parts) be replaced without removing the clutch casing? I think mine is OK but if the clutch housing has to come off to replace the seal I'd rather do it now before I rebuild the cases to be on the safe side.

Ray, just the impeller with a keyway, and the thermostat are accessible. When installed on the bike you will need a wet suit to pull the clutch cover
