C10 Water pump oil seal
« on: October 16, 2018, 03:55:17 pm »
I just pulled the water pump out of my GTR1000 because it’s leaking oil (and 24 year old!).  I got a new oil seal from Kawasaki (P/N 92049-1416) but when I got the original oil seal out of the pump its approximately 3mm smaller than the new part (25mm vs 28mm). Obviously I can’t get this to fit!
Has anyone else had the same problem? Is this just a mistake in packaging by Kawasaki, or am I missing something obvious?

Well if it's a packaging error, they made that mistake more than once.  I have a new seal of that part # laying around and it measured 28mm.  I never used the seal since when I got the pump out, it had more problems than just the seal.  I bought a new pump from Murph.

 :-\ :-\ :-\

Is this a US bike, or a Euro (GTR mentioned) bike?

I've replaced dozens of these seals, using the 92049-1416, and never had this pop up...
is it possible the waterpump was replaced with one from a different Kaw Model, like a ZX900/ZX1000 ninja, or something?
I don't think that would even matter tho... I recall some Euro versions had a pump, that could be dis assembled by pressing out the shaft, which the US models could not be repaired in that manner ( this was brought up during a lengthy discussion about the ceramic water sealing section, not the oil seal)..

I don't know what you have, but the 92049-1416 has been the working part here for decades...

I’m waiting to see what the Kawasaki dealer says today, but I have 2 of these bikes and a spare engine. I’ve now taken out 3 pumps and they are all the same. 
These are all European bikes (UK-spec), but so far everything in the cooling system is the same as described in the Clymer & Kawasaki workshop manuals and of course from the many threads on COG forums.

this is exactly what I suspected, as back in time, the person that posted ( an Italian fellow, and it required much translation to print it) about a w/p 're-build' did it on a Euro GTR bike; and the pump he was building did have some differences that appeared. Just curious, can you look up the part number on a euro Kaw Microfiche, and post the water pump assembly number?
The American/North America part number is
49044-1083   PUMP-WATER  (this part replaced p/n 49044-1058)
that would help us out, I know the older euro models actually had a coolant line that ran up to the carb bodies, to circulate warmed coolant to prevent "icing', primarily on the German models. never had the chance to do ant service to a Euro bike, so I'm sure there are other small differences. Might want to pose this question to some of the guys on the GTR forum, as they may have provided a seal replacement work around as we did.

also, our Australian pals my have input...
http://www.gtr-aus.com/

please report back, we would be glad to add it to our database.

EDIT TO ADD:
I went to numerous suppliers sites, in Europe (UK, FR, ) and found the exact same part numbers I have noted for the water pump, and also that seal... so I am at a loss of what is in place, you may end up purchasing a complete water pump, if so, please report back the seal size in the new pump, compared to the defective one,
best of luck, sorry for the lack of help here,

The water pump is on and clocked up 150km today. Checked the water level about 4 times today and all looking good. No puddles under the bike either. The fan didn't switch on as the temp guage rose above 1/2 way. A fiddle of the wires on the temp switch and it started. Something to watch in the future. I was paying more attention to the temp guage today than I would normally. Here are the parts I used (part numbers and prices) to rebuild the water pump.

Kawasaki parts;
920551271   Ring-O, water pump   $13.13
920551424   Ring-O, 33.2x2.4   $7.56
920491416   Seal-oil, water pump   $11.67
CBC Bearings parts;
EH790J08DBQ   Seal assy, Mechanical general   $15.40
6001LLU   Bearing, Ball, SRDG Metric (2x$7.70)   $15.40
BS120   O-Rings   $0.33
When I fitted the bearings they were popped into the fridge for about 10 minutes (still inside their plastic bags) and the pump housing in the sun. Bearings fell into position. A 21mm spark plug spanner is the same size as the bearings and seal for keeping them pressed into place.

Might help a little further in the issue. Cheers,

Crack a tinnie for your efforts,

I checked all the microfiche web sites in the UK and other countries, always selecting the UK variations where possible and they all showed p/n92049-1416 as being the correct oil seal part.  I spoke to a couple of dealers direct and they also thought that it should be the correct part.  However, I have 3 water pumps from 3 different engines (1991 A5, 1994 A9 and 1995 A9) all using a smaller oil seal.

I then called a seal and bearing specialist who advised to look closely at the seals I have got and on 2 of them a serial no. ‘S12257L’ was embossed on the inner face.  He identified that this was in fact 12mm inner diameter, 25mm outer diameter and 7mm thick.  I ordered the seal and it was a perfect match and good fit.  Construction of the seal was also identical to the original item.

Happy days, now I just need to get the rest of the cooling system back together.

congrats, glad you got hooked up...
as for the seals, this was the FIRST time this ever came up that I know of in 15 years of Concours ownership, and I was the Tech Editor for a while, so I'm very surprised.

Now I have to go and check the seals I have, to see what they are, and if they are marked in a similar manner, both new ones, and the ones I pulled during replacements.

that number you supplied definatly does describe the size, and I never disputed it, just never had it come up..
great job, thanks for your info also... :great: :great: :great: :great: :great: :great: :beerchug: :beerchug:
