Clutch adjustment - pedal not fully returning?

[proporsche]

maybe you had a problem with your Omega spring ..but..the OP spring is in pretty good condition as you can see on the video;-)

I would remove the small arm and see if the larger arm is binding on the shaft. It should turn freely.

Thank you Ivan and Pete.

I will pull the "little finger" and inspect the larger arm to ensure it can turn freely. Ivan, you say I will "see the problem". Can you describe what I will see? Will the larger arm be binding or stuck? Is something improperly indexed?

I can "release" the omega spring so it taps the heat exchanger ever so slightly in the current configuration.

I can wiggle the exposed cable when it it adjusted properly. It is taunt, but not so tight that I can't move it. How should it feel?

[proporsche]

lets say, remove the little finger and clutch cable, then we see if the arm is frozen on the shaft.. then report.. again loosen your clutch cable should be the first thing.. before you do anything..

There's a few different videos on youtube that show the same as your pedal.
If it looks like yours...email them.

That exactly it. Hunting for contact info for the person who created that video.

I also plan to follow Ivan's instructions as well.

Is it sticking or is there free play past the point where the short arm stops ?

If I had to pick between the two, I would say it's play. That said, it kind "bumps" into position for the last inch. The videos show it better than I can describe.

Ivan,
I removed the little arm.

The big arm moves freely. In fact, I moved it a little and the tension from the omega spring swung it freely. I can take more pictures and video.

What should I look for next?

[Locker537]

From the Bentley manual:

"If the release lever will not slide off the clutch cross-shaft, the pedal stiffness problem may have been found"

Could that be it?

Also of interest, the omega spring does have a little wear / divot where it rides the pivot pin on the transmission. I can replicate a similar binding by hand.

The release lever of this car has a pin next o the cross shaft, which I assume is retaining the lever.

Maybe this will be of some help....https://www.pelicanparts.com/techarticles/Mult_pedal_cluster/Mult_pedal_cluster.htm

Be sure to read the comment by Norm Smith at the end. Is it similar to yours?

I don't think so. I'm working under the car at the transmission, not at the pedal assembly.

I believe the pin needs to be removed for the lever to slide off. Earlier versions like mine don't use the pin so I can't confirm.

I probably should have said....skip the article, read the comment.

The comments about roll pin and pressure plate replacement from Norm? No, I don't believe that is related to this.

I did not have hard shifting or any other real issue. I was attempting a routine clutch adjustment and have ran into this "pedal not fully returning issue".

My hunch at this point, is that the omega spring is not actually broken, but where it rides on the shaft on the transmission is worn and there are two humps. Jumping between the first and second hump is the cause of that last inch of pedal travel binding up.

Just my working theory at this point. I took more pictures and video and will share when I am back to my other computer.

The cable, pedal cluster, long arm doesn't look or sound like they're sticking from your videos or description. I'll go with the omega spring.

My clutch pedal is the same, been that way for a while...

What i have been doing is putting a bungy cord around the clutch pedal, fastened to the steering wheel, to keep the pedal in place during the adjustment.
Once the adjustment is complete I remove the bungy cord and everything is fine. Great clutch engagement. Good luck.

THIS. ^^^^^^^^^ Yes.

I had this today during my first ever effort to adjust the clutch cable. For me, it was resolved by adjusting the clutch cable housing nuts to pull the clutch cable release toward the front of the car.

It took several efforts, but I went from zero clutch engagement with a floppy pedal, to partial engagement with exactly what is in that video, to a high-pedal clutch engagement to something normal (mid pedal) after that many tries.
