I looked back (did a search) trying to locate a ready made set up that would replace the old clutch cable stuff and replace it with a Hydraulic/slave cylinder configuration. I found a few photos and a few posts saying there would be a kit forthcoming, but up to this point I haven't come across it. (IMG:style_emoticons/default/confused24.gif) Also saw a "hydraulically" actuated throw-out bearing. (IMG:style_emoticons/default/confused24.gif) This would be for a stock 75' 2 liter and tranny.
Also want to keep the pedal locations stock (I'm tall) the car also has the front and rear sway bars. Even more importantly does anyone have experience with either set up. Any thoughts or pointers in the right direction would be great. |

Don't think anyone offers a bolt-in kit, though several folks have done this conversion. The hard part seems to be fitting the clutch master cylinder. If a kit would become available, I think many folks would be interested to get rid of the clutch cable.

I just don't see the point unless you have V8 conversion or similar with a big heavy clutch,not an easy conversion...and yes no kits out there cause there is little or no interest.

I desperately need something like this for dad's car along with some sort of button operated actuator as my dad can't push in the clutch very well any more

The auto stick bugs did it with vacuum. There was a switch in the stick shift handle that actuated clutch when you pressed down and also when you pressed brake.

The hydraulic clutch was done years ago by "a914guy" using a CNC slave cylinder and a master cylinder from a 928 Porsche (if I remember correctly). The hydraulic lines and fittings were 3AN size. The line does go through the tube before fitting attachments.
The most complicated factor is welding a mounting plate onto the underside of the body next to the brake master cylinder; then set the arm length from the clutch to the master cylinder (rod does attach to the pedal arm without too much trouble.) Add a reservoir to the top next to the hydraulic one and run a line down and attach. The bottom right side of the transmission with a makeup bracket to hold the one end of the slave cylinder and the other one attaches to the clutch yoke arm using the existing metal shift cable wedge. I think you will find the details either by contacting "a914guy", a search under hydraulic clutches, or getting me off my old dead ass and take some photos. This example is one of the only ones that you can get details to where you can use the ideas to build your own. I built A914GUY's hydraulic clutch which is on my car. I used Wilwood slave cylinder #620-1033 and matched the shorty Wilwood master cylinder to it. Make sure you match the bore sizes as recommended by the manufacturer. (Something like 3/4 inch master; 7/8 inch slave). Hope this helps you. Steve Hurt |

Look at the 944 / 951 this is a stock set up. May be able to easily adapt.

It takes a little engineering but it works. Rnellums did a similar arrangement with his trans even though its a Subaru trans - it works really well. Lessening the effort makes it easier for him to push=better driveability for him. |

With the hydraulic the piston size is close to 1/1 so you probably have plenty of force in the stock 944 / 951 set up. The engineering is done, just a matter of mounting. That's why I recommended this as the 951 clutch is actually pretty beefy from the factory. The torque tube setup makes is undesirable to have to change often.

that's what I do! Group: Members Posts: 20,065 Joined: 27-December 02 From: Port Hope, Ontario Member No.: 26 Region Association: Canada |
Someone else did it with VW vanagon parts.
Hard part is fab the mounts, but that said what I've seen they're pretty simple. |
