GT750 water pump spring seal

Suzukidave · Post by **Suzukidave** » Tue Jun 09, 2009 6:39 pm

I need to replace the spring seal in my project engine water pump , does anyone know if the seals can still be purchased from Suzuki or if not has anyone cross matched the seal to a standard water pump spring seal ?

Is he membrane ripped or is the pump just leaking..

The stainless seat part was really stuck on the shaft so in the process of pressing the shaft out the carbon ring broke and the other pump i had handy didnt have any seal at all . I just may have another case with a pump still in it and i will check tomorrow

Ah well, I guess you'll have to fit an electric water pump and get rid of the tacho and pump drive. I see a high output alternator in your future

Nice idea Teaser but i think finding a replacement spring seal a bit cheaper

Dave. I don't know if the spring seal for the buffalo was ever available separately, but the seal for the RE5 was. Part no. 17470-31010. They look to be the same. Don't quote me though. If you get in a bind, I have a few spares. Cheers.

Dave,

I bought a repair kit off a guy in the UK for that Blue A I restored a couple of years ago and it included the usual water/oil seal and a replacement for the graphite seal made of teflon.

I seem to recall the same unit on the web - maybe at G&Gt spares in the Netherlands.

Thanx Richard , i went and looked around and saw whole pumps and a replacement stainless collar but not the spring seal http://www.knalnaarpotz.nl/ . Maybe i could drop him a email and ask .

You could also try Reiner in Germany as he has a lot of GT750 bits and pieces as well as reproduction parts and kits. His email is GTReiner1@aol.com.

Reiner's kit has the teflon instead of graphite. The one I rebuilt using his kit didn't seal, but that could've been my fault.

As I have mentioned before, I searched and searched a while back for these seals. I found a company (also in China) that would make them. I sent my contact one that I had and he said no prob but I had to order 2000 of them!
Thinking on this some more these seals must be available thru other applications. I know I have seen them on appliances like dishwashers or dryers.
If anyone finds one please let us know, I have 3 waterpumps sitting in a box all needing this seal.

Yeap it didn't seal for me either.Had to cut notches in the inner Diameter to fit over the Pressed sheetmetal sleeve.I wound up buying a new pump in the long run.

Likewise I also had to cut the notches, and it did take a few runs before it sealed. It may have been better had I used a new sealing seat (part 17476-31000 - the metal plate that presses against the Teflon seal) rather than reusing the old one

. At any rate, it seems OK currently.
