Can you convert a 72 manual clutch to a hydraulic setup?

I've got alot of questions don't I

I'm getting ready to install a 915 tranny out of a '72 911 in my project car and was wondering if anyone has converted over the manual clutch to a hydraulic setup. Any info would be greatly appreciated!

Thanks!

I have seen this done on a 915 recently. A friend of mine is a US distributor for a 904 reproduction from the UK. Anyway, this thing has a 915 box with hydraulic clutch. Basically they mounted a slave cylinder under the tranny with a long threaded rod (for length adjustment) that pushed on the clutch arm. The arm had been removed from the shaft and put back on at a different angle but that is irrelevant as long as the distance that it is pushed is the same as what the cable was pulling. It was a later 915 like mine but the principle is the same. It is actually pretty basic. I would think the only hard part would be mounting the slave cylinder and running the line through the tunnel.

Why would you want to??

G50's use a hydraulic clutch, but all 915's use a cable clutch.

I'm sure it can be done if you have the know how or money. The bell housing may need modification to adapt to a slave cylinder, but otherwise you'd need to adapt the pedals, lines, and setup some sort of reservoir system. That might be a pain too, the G-50 setup uses the fluid from the braking system.

Well, I'm putting the 915 tranny in my 81 DeLorean. I already have a Chevy engine in there and also the parts to mount the tranny to the engine, however, the DeLorean setup is hydraulic. I guess either way won't matter too much because right now my car is a stock auto DeLorean tranny. I was just thinking it may be easier to use a hydraulic setup since that's what stock D's came with.

Thanks for the reply!

You wouldn't happen to have a source for the parts or an email addy so I could get more info would ya?

Interesting project. I can see that you wouldn't want to move away from the Deloreans hydraulic setup if you don'r have to. But, and I'm sure I'm not the first to mention this, but the 915 isn't a M21 in terms of Chevy (SB?) torque handling. (I'm sure you're aware, but I just thought I'd mention it)

Alrighty then! I couldn't think of a reason to do it, but you got me. It does make sense to make it hydraulic. I can't help you, but I work with a guy with a Delorean that will probably be interested in hearing about your project. Good luck
