water pump repair kit question

Post by mick 63 »

Hi All i managed to remove my water pump today to install my repair kit i bought from Crooks Suzuki here in the uk,
i have a question regarding the Mechanical seal,
i have managed to strip the pump,
apart from the metal seat part of the seal, it seems to be bonded in either that or it is really tight ,
do i need to change this part & if i do how do i get it out ?
please see photo,cheers Mick.Image

Well - I suppose it depends. :? Here is a linkto some info on the pump. If you have damaged the rubber bellows then you are scuppered and will need to buy a new pump sleeve as this part is not available separately. The bellows fitting is a tight fit, and here is some sealant that holds it in on the top side of the pump sleeve. The face of the seal on the bellows side is quite fragile - replacements are available in Teflon, but some board members have had trouble getting them to seat properly against the stainless steel seat. Are you replacing the SS seat ? if not, then you may want to lap it smooth before re-installing to try and ensure it has the best chance of sealing against the bellows seal face.

Not sure if I've answered your question ......... what was included in the repair kit from Crooks (which is an unfortunate name for a dealership isn't it ? 8) )

Correct - as I mentioned in my earlier reply, the bellows are held in with sealant as well as being a tight fit. Good to hear you are having success ! Just curious - what was the part number for the Crooks repair kit ?

Hello Ian, on my first phone call to Crooks i asked for a water pump repair kit & a gasket for the water pump cover.

i had to wait for the mechanical seal as it was out of stock, i recieved my parts and soon realised that i would have to order additional parts,

so i ordered the bearing ,oil seal that goes under it, 3 o rings, & the 2 circlips total cost, £54.37,

you would have thought that Crooks would have known what goes into a water pump rebuild ?

there isn't a part number for the whole kit just part numbers for individual parts,

my friend who works for a major pipelaying firm here in the uk as a small tools repairman had a look at the mechanical seal and said that it is very similar to the type he uses in water pumps etc, so i'm thinking i could maybe get these from my local bearing / seals supplier ?,

the part number for the mechanical seal is 1740031809p

i'll let you know if i have any look with the supplier, cheers Mick.

Thanks !

That is odd, as none of the GT750 parts lists I can find show the seal just by itself. What they do show is the cartridge sleeve with the seal installed under part number 17400-31809. The only number I can find for the mechanical seal by itself, is 17470-31010 as it was also used in the RE5 but is no longer available from Suzuki. Just double checking Reiner's latest listings and it does look like he has a few of 17470-31010 left, as well as a reproduction part under his part number 17470-31010-000-Z which I hadn't noticed before, so I'd put money on your comment about something similar being available elsewhere. 8) 8)
