Title: Clutch pedal doesn't come all the way up
Post by: Rocket80501 on March 29, 2019, 02:55:47 PM

We have a '66 Mustang convertible, and '66 Hertz, and neither clutch comes back to top after using clutch. Both are adjusted with about 1 inch free drop before engaging clutch, and have new springs that go to clutch lever on bellhousing.  Thanks for your suggestions. Ron

Usually the pressed bushings in the pedal support are excessively worn, you might check that.

Can you place your tip of your shoe and pull it up against the stop?

Time to check travel and any possible obstruction which can turn up in a number of places in the system from the trans throw out to the pedal.

All bushings and nylon bushings have been replaced. Convertible has regular Ford type clutch, and Shelby has Centerforce, I think. They are adjusted with about 1 inch free fall. They have been like this for years, and I don't like to have to hook my toe under the pedal to bring it back to the top. Going to have the clutch, pressure plate, throw out bearing, and pilot bearing replaced on the convertible, so will see how it acts after all that is finished. Ron

Is the over-center spring on the underdash pedal support?

They both have the heavy spring up under the dash.  Ron

What happens to the clutch linkage from the "Z" bar down to the bell housing when you "pull" the pedal back to the top? This is a two man task.

When you pull up on the pedal, all of the bottom linkage moves as it should, but looks like the linkage is hitting the header. Ron

Could the under dash spring be missing its 'half moon' plastic bushings?   There's one on the pedal and one on the bracket that bolts to the pedal
support.

Under dash spring and both bushings are there. I think I found the answer, the bottom arm on Z bar is hitting on headers. Ron
