Clutch rod to pedal, help

[twalker]

Need help, anyone have a picture of where the clutch rod mounts to the pedal?  I'm converting from automatic to tremec and can't seem to find where to mount the heim joint, guessing I have to drill a hole...

Does your pedal have a spud on it? if it does, knock it out and that is where you need to connect to. Ratio needs to be 6 to 1. IE if pedal length is 12" you need to connect it 2" from the pivot point. You need this mechanical advantage. I connected mine (as seen in photo) a bout 1" below the stock location. I have since changed it to where the stock spud was. The pedal was too hard to push where I had it in this photo. In the photo you can see the stock spud just above where the heim is bolted.

BIG help - will have another look and post up my results later today.  Thanks

Ok, got it mocked up.  Seems to work well, nice fluid motion and no binding.  Anybody have concerns or suggestions?

Mocked up, firewall:



Mocked up, pedal side:

I don't see a pedal stop. Make sure you don't overstroke the master cyl. I also found that the firewall would flex with my setup, so I made a brace going down to the frame.

Hmm, my kit didn't come with a stop, did you make or buy yours?

[jhaag]

Made it. My system is home brewed not a kit. You can see the adjustable bolt on the reinforcing plate in the photos above. You just need to make sure your pushrod does not travel more than stroke of the master before the pedal hits the firewall or whatever stops it. Overstroking the master could blow the seals out. Most installations I have looked at needed a pedal stop. Call the tech line of the kit manufacturer and see what they say.

I have a similar setup w/ a hydraulic clutch and the heim joints.  I'm converting from an auto to a manual.  How did you modify the brake light switch bracket?  In the stock location, the bracket contacts the heim joint.

Yepper it does, I'm just about to trim the bracket, will post a picture up later today.  How does the rest of my setup compare to yours?

Thanks, that would be great.

I've got a Keisler kit I've been sitting on for a while and finally got around to installing it. There are some differences but overall it looks similar to what you've shown.  I do like the adjustable mount for the clutch cylinder. Seems like that can handle build differences better than the fixed mount Keisler used.

The Keisler kit came with the clutch pedal and parts to convert to a manual setup.  The hole for the clutch pivot was already there.   There was a spacer to move the heim joint out (~1/2") away from the pedal.

Ok, set up nearly complete - just have to build a pedal stop.

Here is a pic of the modified brake pedal switch.





And a couple more of the setup.

Thanks for the pictures. Looks like a very simple mod. Nothing near to what I thought I had to do.

I bled the clutch last night. It feels good to actually have some pedal resistance. The high pressure line on the Wilwood MC was a PITA. It had a slight leak but eventually stopped after taking the fitting to what I thought was near its stripping point.

twalker, noticed a couple things, and maybe this is just a mock up for you. There should be a rubber bumper where the up stop on the pedal hits the pedal bracket. Keep it from making a clanking noise. Your pushrod may need to be lengthened to raise the pedal height, adjust freeplay, and allow enough pedal stroke. There is a reinforcing bracket available with studs that goes through from the engine side of the firewall where you have the 2 bolts for the bracket that the clutch pedal hangs from. Little things, just thought I would point them out. Parts available from Brewers or Roseville.

Thanks jhaag, I have a rubber stop I can put in there.  Wasn't sure I needed a brace for the firewall because it felt solid, and the steering column isn't in yet.  I'll look up the bracket on Roseville and make a decision.  Thanks again!
