Hydraulic slave cylinder...how did you do it?, I know there has to be a few running a hydraulic clutch setup... Options

[Mueller]

The thread about BDSTONES awesome rebuilt pedal clusters got me thinking. .."how the heck do I activate my hydraulic cylinder that engages the pressure plate?" for my transmission?

Pics would be nice if you modified the pedal cluster.

[SirAndy]

Paul Sayegh did a hydraulic clutch on his car. I'm pretty sure he posted pics here somewhere.

Mike, I am currently doing a hydraulic clutch (puller type slave) which uses the Wildwood master and slave. Same that Rich Johnson uses on "Old Yeller" down in Texas.

I may have some other information on other types such as pusher slaves, etc.

Let me know and I will look up/forward the information.

I think the slave cylinder is the easy part, mounting the master cylinder for the clutch is the more challenging part as it would require more fabrication. If someone would come up with a bolt in(well, weld in) kit, I think many of us would love to do the conversion.

Yes a no brainer kit.

That's actually pretty simple, cheap, and bolt-in. Look on pages 7 and 8 of THIS thread of A&P Mech's build. It's something first done by 76-914 (and is in his build thread) that I also copied for my son's car and it works great. It uses a plate to locate a Honda master cylinder forward of the pedal cluster, then uses the cable hook on the clutch pedal for the M/C pushrod. Drill one hole, for the pushrod. I think I paid about $25 for the Honda M/C. That one pushes the Subaru clutch slave perfectly, if your slave is a different diameter/stroke you'd need to choose another M/C to fit.

In his build thread I think 76-914 even had a template for the plate, and if you use a slightly thicker gauge you won't need the bracing that A&P Mech put behind his. Mine didn't need it anyway, but I think that's mentioned as well.

DB, Kent's Honda set-up didn't quite work out (IMG:style_emoticons/default/dry.gif)

I ended up buying a Wilwood M/C and slave and going the same route that Rich did.

Kent cut the hole in the forward bulkhead floor for the M/C and I installed a small reservoir next to the brake system's reservoir with a hose to the M/C's location ... just need to fab a mount for the new M/C (and possibly one on the trans for the slave).

I'll be diving back into this task on a spare trans shortly, so I'll post my progress ...

[DBCooper]

The slave end didn't work? Or the M/C end? I know the M/C (pedal cluster) end works because my son's car and several others use it successfully. In fact in the A&P Mech thread mentioned above it works and he says he's pretty happy with it.

I think Kent was working on a slave kit for a 901 transmission too. I don't think that worked out, and may be what you're thinking about, but this is not that.

[A&P Mech]

I did fabricate a hydraulic clutch system for my car. I copied Kent's setup. It works great and it is well worth the effort to create. In fact after rnellums drove my car earlier this week he said that he was going to replace his cable system in his conversation with it.

It truly is a great setup.

Strawman has a good setup with the factory pedal cluster.

[Dave_Darling]

Look into the 87+ 964 pedal cluster. I believe they had similar space constraints to us, and still made the hydro clutch work.

For the slave cylinder, you can use one of the annular ones that replaces the whole throw-out arm and bearing. Or you can use an actual cylinder and link it to the throw-out arm.

Yes, it was on a 901. We weren't getting enough throw with that set up.

I need to fab a bracket for the M/C because the orientation of the threaded studs are @ 0 and 180° vs. 45 and 90° like the Honda M/C had.

It will be a 'build it and see' what works best approach. I've seen a few installations where the slave was simply mounted to an extended stud on the side diff cover with a heim joint. Just not sure if that will be strong enough, so it may need a bracket to spread the load (IMG:style_emoticons/default/confused24.gif)

Here is how I solved the clutch master cylinder issue on my 914/LS1 conversion. This solution assumes one will install a center console to cover it all up.

Thanks all...

Some slick ideas.

Slave cylinder built into transmission so one less thing to worry about there.

If you can wait til after the holidays, I'll send you a copy of my master cylinder mount.

It's awesome. You will like it.

Talk to Paul. He's busy with his new life and trying to sell the 914 but he did put a lot of engineering thoughts into his clutch setup.

I've driven his car and the clutch was smooth as butter ...
