That right there is some classic bubba work.

You guys are awesome!
My clutch pedal went to the floor, and I was just about to order a new cable when I saw this post.
Checked last night and found a sheared roll pin.
Everything else seems tight so no pedal cluster rebuild needed, but I cant find the roll pin at AA or PP.
Any idea where to get the right one, so I dont have to use a screw or nail? (IMG:style_emoticons/default/biggrin.gif)

This seems to be a common failure point.

Also the metal piece that that connects the gas pedal rod and the cable; mine bent awhile ago and had to have it welded.

It's like the metal turns to Play-Doh

I recently had the same problem,,, instead of a roll pin I used a solid pin. It won't break again....

[toolguy]

after you get it out of the car and disassembled, look and see if the hole can be salvaged by redrilling to a slightly larger roll pin. .
looks like the PO tried to use a bolt. . . the pin needs to press in firmly with no wiggle or slop. . . the bolt was probably loose and part of your clutch adjusting adventure.

If you can redrill, do it with the arm on the shaft. this will ensure the hole is perfectly aligned all the way through.

I bought a roll pin today...any hardware store/Lowe's etc will have a drawer of them in standard sizes...for my flywheel/crankshaft. It was $0.30. A roll pin...or tension pin as it was listed at the store...is designed to compress as it is pressed or hammered in in order to remain in place. A solid dowel pin will be stronger but won't have any tension holding it in place and you will need to jam it in there.

I've rebuilt only a couple of these pedal assemblies, but the first thing I did was punch out the roll pin in order to disassemble things, then clean and paint. reassemble with a new roll pin.

Much better than Bubba's approach and I bet you are glad you were uphill from home.

Good luck.

The roll pins that do not make a complete circle (e.g., the most common ones you get, including at one point the ones in the Weltmesiter bushing kit!) are not up to the task. There are "spiral pins" that are more or less a spiral of metal and have several thicknesses of metal holding the pin's shape rather than just one. Those are much stronger, but they may be harder to find.

(Think of an "@" instead of a "C".)

For a while, we had a rash of failures shortly after the brass bushing kit was installed. Not sure if that's still the case, though.

[A&PGirl]

The actual spiral like Dave mentioned appears to be NLA & no longer imported by general distributors in to this country in the right diameter x length.

Importing seems to be the only option. I found a factory in Germany, but I don't know if they'll export.

Lovely. Why does everything on this car require a contortionist?? (IMG:style_emoticons/default/dry.gif)

I can't tell if the f'd up hole was ground out by hand or happened over time. Classic.



Other side:

[7TPorsh]

The rest of the cluster looks ok. Did the factory use brass bushings?

How does it come apart?

That pedal is toast. Get in touch with Bruce Stone and see what he wants for a pedal assembly. He might even have just a pedal to sell ya. I would guess, he also has a box full of roll pins. I've also found, it makes it a lot easier to do this job by taking out the seat and removing the steering wheel.

Current price is $200 with a good core. I can build one from finished parts I have without you first sending yours to me. No charge for the lower clutch pedal but the hole in the shaft looks very questionable. Last time I checked the shafts were about $40.

edit: Seems the shafts are NLA. I have core pedal sets that I can pull one from.
Also note that the lever on the brake light switch is twisted like a pretzel. I have them too. I wonder if your brake lights were even working?

The roll pins I get in the bronze bushings kits are the spiral type. I have not had a reported failure out of the more than 200 pedal sets I have rebuilt. I do grind down the edge and taper the end to insert them so they do not telescope.
I have been tempted to use hardened dowel pins in place of the roll pins.

I think most of the reported pin failures can be traced to the pins used by the Weltmeister people in one time period. I also don't like the idea of a hardened steel pin because it doesn't allow for wear or variations in the size of the holes, puts a high level of stress on the material surrounding the hole (especially the casting), and has to be peened or otherwise secured in place. 356 differential locking pin failures are one good example of the problems associated with solid steel pins. Differential housing failures were rampant throughout production.

I ended up drilling and tapping with 8x1.25 threads and installing ss nut and bolt. Por15'd floor and pedal assembly last night. I will see how everything fits tonight when I put it all back together.

[7TPorsh]

Be careful of the nut and bolt...

Look what I ended up with:

bdstone: "Also note that the lever on the brake light switch is twisted like a pretzel. I have them too. I wonder if your brake lights were even working?"

Yup, brake lights were working...I fixed that awhile ago. that's my handywork from when I discovered PO had it bent and installed on the wrong side.

[BK911]

Look what I ended up with:

Yea your picture concerned me a bit.
But it looks like your po installed a cheap bolt that would slide right in.
mine is a larger ss bolt threaded through. Should eliminate any slop.
But we will see, time will tell!
Good luck with your fix.

BK911 - I did the same thing for my rebuilt pedal cluster; just used a metric SS nut & bolt, but I used a locknut and lockwasher on the bottom of the bolt to keep it from coming loose.

And, 7TPorsh, as long as you're that far into it, it's worth your while to rebuild the entire cluster with the bronze bushing kit.
