slave cylinder rebuild kit/ seal suppliers?

[straker]

Hello,

I remember years ago I could go to my local car parts shop, a bit like Bullseye are today, and they would be
super helpful in locating the right seal kit to rebuild an old clutch slave cylinder. Well I find myself in a
similar situation now, I have the slave cylinder ( a different one ) in my hand, and I'm trying to get a seal for it.

Its a bit technical for my local Bullseye guy, and all the other major stores want a reg number or the computer says NO! . . . .

The problem bit is I dont know what the slave cylinder is originally from, I have it in my hand so can measure it, and know
what size seal I require, I even got the embossed number off the seal which should identify it, but having difficulty finding somebody to supply me with one.
The details embossed on the seal are " aisin 90947-01048 "

Ive done some googling but havent found much help there, maybe I'm doing it wrong! . . . google suggest a totota seal may fit but i'm not sure.

Can anybody recommend a dusty old store with a backroom full of new seals, and a shop owner who knows just where to look in a huge pile of 'junk' to get the right bit for me? !

If i get desperate I'll buy a new slave cylinder and make a bracket to make it fit!

thanks . . . .

You may do better measuring the seal(s) and trying a local seal specialist - taking the seals in would be an idea.

Or using the measurements with an online company such as (quick Google):

thanks for the link,
I went to my local " city seals and bearings " , they dont do anything car related, apparently the
brake/clutch fluid requires a different kind of rubber to hydraulic fluid . . . so they couldnt help, but I may call
the link you posted, would I expect the guy on the phone to know the difference? I dunno :/ . . .

They were a random Google.
Just noticed I posted the 'simply bearings' one twice - I've changed it.
Good point about the seals being different - I do know that brake fluid can adversely affect some rubbers but forgot to mention it, so a 'D'oh' moment!
Well known bodge to stick some brake fluid into leaky power steering systems to cause the seals/o-rings to swell & temporarily stop the leak.

I'm a little suprised they can't identify by the number but it may have been an uncommon application.

Unless the component is pristine as regards wear/corrosion you may be better going for a common new complete unit which would also make it easier to source a replacement in case of later repairs.

yeah I'm currently scouring google images for a close fit! . . . . i think getting a new one that i know the identity of
is the way to go . . . I may have to adapt the linkage to get the same movement but its all do-able . .

gone are the days when I went into the shop, and the guy dusted off his girling/lockheed book with all the sizes cross referenced with part numbers . . . . do those places still exist? guess they cant compete with the internet . . .

I worked in a motor factors in the mid to late 70's & we did sell quite a few repair kits.
That said, more garages preferred to replace the whole item than repair the defective one as pitting in the cylinder bore could be an issue.

I think some still do stock them, but the last wheel cylinders I replaced on our own cars was in the late 90's early noughties & I just replaced the whole thing to avoid doing the job twice!

I've done the seals on the calipers on my RRC but replaced the pistons with ss ones whilst I was at it. All parts ordered online.

Can you post a picture of the slave cylinder and explain the application it is fitted to? Someone might recognise it and be able to point you to the original application for either a replacement unit or seal source.

any tips on how to upload pictures? do I have to join a hosting site? . . . .

ive used the search button for an up to date explanation but it wasnt that helpful, i'm not super literate on
these computer contaptions so simple explanations please

[straker]

meantime I've just bought another slave from ebay, it isnt a perfect match physically but looks close, so I may have to re do my bracket a bit, and hope that the bore size is similar . . . .

If you're using a PC / Tablet or laptop, first save the pic you want to upload into a folder (remember where the folder is located on your gadget), then click the link above which says "upload an image (beta)"

click "browse"

select the pic you wish to upload and click it, it'll then automatically fill in the "path" to the image (if it is in a folder, click the folder to open it)

click "upload"

it should do it automatically. If the pic is too big you'll then get an error message so you'll need to downsize the image with image resizer which is a very small plug in program free off the web.


Edit *
What do you need the slave cylinder for?. I had to replace one on my Lancer, after some cross referencing with the OEM number, I managed to get one but the casting was a different size, however luckily the I/D of the bore was the same so hopefully you might be lucky as well.

well that upload business appears to have been pretty easy!

as for what does the slave do . . . . .

I have a longterm track street project car, and want to keep it oldschool manual, I cant work a clutch pedal
with my busted leg, so am using a motorcycle hand clutch mounted on the gear lever, through a vacuum servo, to the slave cylinder mounted under the dash acting on the original pedal at the right point to give correct travel.

this also means my car can be driven normally by friends too . . . .

there are clever alternate electric/hydraulic solutions out there but they are not really within my budget, this isnt perfect but works well enough for now . . . . except for leaking fuid on your foot when the slave seal leaks!

thanks for the replies . .

Just a quick Google image search came up with this as a possible match for your slave cylinder geometry? https://www.carbuilder.com/uk/13mm-bore-clutch-sla...

It is a search of google images, see below.

I think over the years with the multiple 1000's of different such items suppliers just don't bother with rebuild kits for a £15 item as they would rather sell that than £2 rebuild kit.
