Thread: 57 Chev Clutch Pedal Installation

Tweet

Going back to stick in my 57 using my old clutch pedal, which I saved 10 yrs
ago, but am having trouble with the pedal sticking to the floor when pushed
in, and it will not return on its own..Looked at a diagram, thought I had it
right, but something must still be wrong..Has anyone had a problem similuar
to this before..

Assuming your linkage is in the right position and functioning right, the diaphram is either collapsing down or your throwout bearing might be wrong, as in being too short maybe. A mismatch of parts like using a diaphram pressure plate and a three finger type throw out bearing can cause some problems too.

Do you have a return spring on and hooked up right?

Just now puting pedal in....No other hook ups done yet such as forks, z-bars
etc...Has to be something small I am doing wrong with the spring. R dobbs

Here's a picture that may help - make sure the top spring (3720151) is the correct one ant that it has good tension. Lube it where indicated. Also the shaft that the clutch pedal rides on must be lubed. the pedal is not intended to go all the way to the floor, rather it should hit the rubber bumper (3723230) before going over center for the spring.

Remember too that when all components are installed, the spring in the clutch diaphragm (pressure plate) will assist in the return of the pedal to the top position.

Hope this helps,
Glenn

Glenn, I think you have helped solve my problem as I have nothing else hooked up yet other than the clutch spring...I already had your diagram, but
there is also another one at tri five library that shows the long stem of the
spring being hooked into a plate about 1 1/2 in long...this plate then slides
over the lever assembly bracket which has a grove in it..This is the way I
have it hooked up now....Also, what is not shown is, there is a small rod
running thru the channel towards the dash with a hook on it..This is where
I hooked the short end of the spring...................If you have any other
coments, let me know, but I think the fact that the whole assembley is
not together yet may make the difference....Thanks R. Dobbs

It sounds like you're headed in the right direction - get everything installed, make sure all friction points are well lubed and move freely and I think you'll be fine.

Regards,
Glenn

I may wish I had a hydraulic clutch before this project is done..I will be
running a 11 inch clutch and plate, , but thus far my left leg is pretty
strong for my age.....thanks r dobbs

If you do a bellhousing from an early 60's pickup will work as they were hydraulic.

Ntfday, did not know about early 60's hydralic bellhousing..would
consider that approach, but have to have a scattershield in this
one to protect feet and legs......thanks r dobbs

The one I have in my garage was behind a 283 in a 62 1/2 ton.

make sure you have the return spring on under the dash the pedal should be in the up position at all times even with out any linkage.since you have nothing hooked up with out the linkage installed it will go to the floor but if you pull up 0on it should snap back up.
