Hydraulic Clutch, This works GREAT! Options

[PRS914-6]

Seems like there is always interest in converting to a hydraulic clutch. Using a 911 clutch gives a bit of a stiff pedal but my biggest complaint was I didn't like the modulation and feel especially using a performance clutch disk. The 914-6 cable is much smaller in diameter than a 911 cable and aggravates the problem. In addition, my first gear is really tall and with a clutch that felt like it was on/off was a little annoying and down right scary when stopped on a hill with someone on my ass.

I picked up a new generic master cylinder and pull style slave (available at most any buggy shop for under $150.00 I also picked up a 4 ounce remote reservoir.

I made a plate that fit under the brake master cylinder and a bracket that fit on the side cover of my 915 tranny and ran the hydraulic lines down the tunnel. I also installed a bracket from the plate to the I beam of the suspension to eliminate any flex.

I'll cover the entire installation in a future issue of Excellence with the project car (at Pete's discretion) but here are a few pictures to show the method I used. The "feel" and modulation of the clutch is dramatically improved. Absolutely smooth as silk now.

Larry hubby did a nice write up back in 2008 with some nice detailed diagrams using 944 factory parts. Halfway down this thread

I am following Larry's example using the longer 911 clutch shaft and a bell crank at the transmission side to allow use of the 944 slave.

I did not create the nice aluminium shim Larry did due to my lack of machining skills but did a flat plate like Paul S.

The thicker plate also between cluster and brake move the master away from the cluster by 1/4" but you can make it up with adjustment on the rod. I also shim my brake, clutch pedals down a little bit to give my self more legroom.

Created a brace at the same time.

I also created a splitter down at the brake to share the rear fluid supply with clutch slave so I don't need an extra reservoir for the clutch.

I have not done the rear but my front looks like this, similar to Paul S.

Hardest part is running the hard line through the tunnel and back to transaxle cleanly.

I think this is Larry's slave setup. Could not find original post on this pic...
