Leaking clutch slave cylinder

It is a 1" bore cylinder with "S-134" cast into the side. Does anyone know what replacement seal I need?

Thank you.

Sounds like you over extended your slave.
When you replace/repair it you should check and see if a clutch pedal stop is in order.

Forget the rebuild kit - go to Napa and pick up a new one for $50.

Phil,
Paul is in England. I am not sure if they have NAPA stores.
Aren't they the Wagner slaves?
What is the part number for them?
Is this the right slave Wagner # SC124111?


Paul,
You might have over extended the slave from day one and blew out the seal.
I am just guessing or it could have been bad from get go.
Call Bill at SA and tell him. He might just send you a new one or get him to give you the brand and part number for it so you can find a UK source for the slave. As Phil stated they are not expensive.
Finding the proper O-ring could be a real PITA.

Another thing you could do is call the Kirkham Bros. and asked them what slave set up they use for there cars. Sometimes it is a matter of using the slave that works with there clutch master.

Hi Tony,
If anything, I don't have quite enough travel, rather than too much.

Clutch pedal travel is affected by the master cylinder size -- the bigger your master cylinder is the less travel you need to get the same movement at the slave, albeit at the expense of additional pressure under the toes. In order to gain additional room for my long legs, I use an oversize Tilton, along with the stock BMW slave, on my ERA. Pedal configuration, master cylinder size, and the slave all need to work in harmony. If not, then you end up blowing your slave, or not fully engaging/disengaging the clutch. Here's a shot of my hydraulic setup; I'll give you part numbers if you're interested.

I was lucky enough to find a repair kit at a local motor factors. It's a Girling Lockheed unit apparently.
I'll put it back together this afternoon and see how it goes.
Thanks for the input.

I think my master cylinders are Willwood (if that's what Kirkham fit as standard). However, I would be interested to know what your slave cylinder is.
Thanks.

Looks like a CNC.
