Hydraulic Clutch Conversion
I am looking to install a hydraulic clutch to replace the old mechanical system. This will make it easier to operate and also do away with stretched cables and Z bar issues in the future.
I would like to see how you mounted your clutch master cylinder and whether or not you use a hydraulic throw-out bearing or traditional slave piston to release the clutch. Any help is greatly appreciated! |

I previously ran a Mcleod hydraulic throughout bearing with my T-5 setup and never had any issues although it was a major pain to bleed. With my new TKX I'm going to try a more traditional external slave I bought as a kit from Novac. |

Re: Hydraulic Clutch Conversion
I used the Captain Fab kit with T56/LS swap and it worked great. Here's a pic of the firewall side.
I have also used a Novak Adapters external slave on a Wrangler LS/AX15 swap. Good folks to work with. I had to make a stop so I didn't over center the clutch. |

Re: Hydraulic Clutch Conversion
How much easier is the hydraulic clutch on the leg vs the mechanical clutch?

Re: Hydraulic Clutch Conversion
I opted for the Speedway hydraulic clutch conversion and will use a slave cylinder as opposed to the hydraulic throw-out bearing.

Re: Hydraulic Clutch Conversion
Which GM trucks use a cable?

Re: Hydraulic Clutch Conversion
I believe it is all of them...at least through 1972 as far as I know, beyond that I am not sure. I don't know when the hydraulic clutches on trucks became 'normal'.

Re: Hydraulic Clutch Conversion
Before the 67-72 (63-66) they used linkage.
However, 60-62 were hydraulic.

I remember pulling out the z-bar and seeing how worn out the pivot ball was mounted to the engine block. The hydraulic clutch will look so much cleaner without the Linkage set-up. Thanks for straightening me out! This is my first C10 build. Now when it comes to MGBs, I can do those in my sleep! |

I only ended up in this thread because I'm reading up on hydraulic clutch options. The mechanical/linkage clutch just kills my leg.

Re: Hydraulic Clutch Conversion
What are you talking about NONE of these trucks had a clutch cable.

Re: Hydraulic Clutch Conversion
I used Captanfab's kit with a Novak kit on my 71 4x4. My first slave cylinder leaked but Novak took care of it quickly. If you still need or want pics I can get them for you.
