clutch slave cylinder

[wemtd]

While on a fantastic Blat with the local Lotus enthusiasts in the Hudson Valley yesterday my clutch went a little wonky (intermittently soft, didn't return, trouble shifting a few times). I topped up the fluid and got home without incident. Tonight I pumped it a few times: depositing all the fluid onto my garage floor. Since this is an engine-out repair I'd like to have parts on hand before pulling the car apart next weekend.

 

The challenge is a replacement clutch...  So far I've had no success finding a domestic source since Ford only sold that make overseas. 

 

Does anyone know of a domestic source or interchange part # for a Birkin annular clutch slave cylinder? I have part# <94ZT 7A564 AB> from Ford Mondeo circa 2010 in my build notes.

 

cheers

Seems to have been used in the USA

Clutch Slave Cylinder | CS360062 | Clutch Slave Cylinder | Dorman Products

 

Worst case is you have to order from UK and ship - at least you know it is the right one.

Check RockAuto, but remove the spaces in the part number which their search tool doesn't seem to like or automatically remove.  Also, not to raise a seed of doubt, but is it possible you transposed those last two letters?  When the penultimate letter is A that designates it's for the 4-cylinder implementation.  When it's B, then it's for the V6 version (the last letter identifies a very minor revision to the pattern, so typically a part ending in B is the replacement for the part ending in A).  Birkin may use the 4-cylinder version but both Raceline and Caterham use the part intended for the V6.  This post shows the differences between them:

Thanks John & Croc

 

BirkinDirect & Tom to the rescue once again.

He has them in stock. Better price. And certain to be the correct part.

I would trust Dorman products as far as Croc's vertical leap. As a last resort only try and find a better brand, Dorman in junk.

The part Croc gave you is the one I use in my 1999 Caterham with a ZeTec. It fits Ford and Mercury products with 2.5L engines from 1995 to 2004. The LuK part number LS0273.

Well...

here is the post-mortem thus far: looks as though a seal in the slave cylinder failed. I hope this is just an intrinsic failure. But If anyone has other ideas regarding a subtle malalignment or such could contribute to this I'd love to know.

It appears to have failed because the stepped metal center was not held against the trans input bearing retainer by the outer clamp ring by the bolts. In other words, when bolted down, there is a gap between the trans and the hrb metal center and there should not be. This allowed hydraulic pressure, internal spring pressure of the hrb, and expansion from heat to allow the center to move out of the body. The center is typically crimped around the edge to hold it in place when not installed. It also could have been pushed apart a little/unseated just before installation from an attempt to bench bleed with pedal movement instead of squeezing the hrb.
