Clutch Brake Pedal Assembly

Re: Clutch Brake Pedal Assembly

All------


The 68-81 clutch pedal design was very "regressive" design.

1963-66 used a pushrod clevis pin that was part of a bracket that was attached to the clutch pedal lever shaft with two bolts. So, replacement of the clevis pin was relatively easy, even with the pedal in the car.

1967 used a clevis pin with a bracket but the bracket was welded to the pedal lever shaft. This made replacement difficult and essentially requires removal of the pedal to replace it.

1968-81 uses just the bare clevis pin pressed into a hole in the pedal lever shaft and tack welded to the shaft. This makes replacement difficult with the pedal in the car.

Re: Clutch Brake Pedal Assembly

My memory is going, Just looking at my 73. The clevis arrangement is on the brake not the clutch. It was the brake that I had trouble removing the pin. The clutch is as Joe stated. The pin is tack welded onto the pedal lever. My pin is worn down to the point of not trying to salvage it. So I'll be looking for a new pin as well. No point in even trying to salvage this. This pin goes straight into the clutch rod. the clutch rod is flattened in this area with a hole. The pin goes thru this hole. There is no clevis joint as I know it on the clutch. The clevis joint is on the brake. My definition of a clevis is a two pronged fork with a hole thru the prongs and a pin then goes thru the forks. Don't know what a harness is. I was looking for some wiring initially until Joe straightened me out. Like Joe says, grind off the old pin and press and tack weld a new pin.

A "harness pin" is an alternate name for a clevis pin. Try this description:

The clevis pin for the clutch fork, is that pin the same as the one used on the clutch pedal.

I believe the clevis pin for the clutch fork is larger OD than the one on the clutch pedal.

Are you referring to this?

That pin secures the end of the lower clutch pushrod to the clutch fork in the bellhousing; the pin on the clutch pedal arm for the upper clutch pushrod is different.

Yes, I was incorrect in mentioning that this was the correct one for the pedal application. The correct one appears like this one but it's smaller in OD. The following should "fill the bill", though:

The above has a Rockwell hardness of B80 which should be sufficient. So, one can pay about 7 bucks + shipping and have enough for himself and 24 other guys.

Thanks for the information, if anyone needs a pin, let me know, as Joe stated I'll have 24 extra pins.

Re: Clutch Brake Pedal Assembly

Macmaster clutch pin.JPGI went an measured the various parts earlier today and came to the same conclusion on which McMaster pin should work. The dimensions are slightly off but it shouldn't matter. The pin hole is slighter bigger but should be ok. Attached is image of McMaster and my dimensions of the real pin. The only other way of doing this is to buy the clutch pedal assy from the vendors which are about $85. But are these pins hardened? Also when welding, keep the welding time short not to destroy the hardening or place a wet rag on the business end of the pin.
