This is a 12 yr old thread. Bill don't hardly come around anymore. The mustang spring may very well work, IU would try it. Or I would probably find an old school hardware store and look at their selection of springs and find one that would work. But that's just me. Good luck!

 

Thunderkiss1965,

Thank you for your comment and for updating me on Bill. He was a great source of knowledge on this site.

I found one at NAPA just about 2 months ago. Not sure if I still have the receipt but it was a very generic part number that fit a bunch of different makes/models. You may be able to have them search their computer for something. If I find the receipt I'll ping you back. Good luck!

 

cmjacko:

Thank you. I'll check with NAPA.

I am trying to locate the correct location where the end of the clutch spring attaches to. I know that the one end attaches to the throughout bearing fork; however the line drawing in the manual is very unclear on where on the Z-bar the other end attaches. I don't see any hole where the end might go. Mine is attached to the steering box, which I'm sure is the wrong place (see attached pic)! If someone has a pic showing the correct location I would greatly appreciate the help!

Thank you!

On my '65 w/240 and manual 3 speed, it attaches to a small hole in the large crossmember that runs under the engine. Its behind the left engine perch. On my 1966 w/352 I couldn't find a similar hole so I made one with a drill. Seems to be working fine.

 

cmjacko,

Thank you for the reply sir. That's a long spring!! Not sure that's the correct location, but if it works.... The manual shows it going somewhere near the Z-bar, but doesn't show exactly where. I'll look some more. My location appears to work fine, but I'm a stickler for doing things the proper way.

Yes, I agree - the spring has some significant length. I don't think my truck has been modified and I've seen images posted in the past (maybe from master parts catalogue?) that showed a similar looking spring, at least for the six cylinder engines. I looked in my shop manual though and it doesn't specify or show specific pictures as you mentioned. Please let us know what you find out, I also prefer to have things buttoned up the correct way. Thanks!

 

Catalog lists two clutch springs for 1964/66 F100/250 2WD and 4WD (except 1964 4WD which used a different spring) all engines. 4.60" length was used before serial 830,001 and 9.16" after that serial. The spring CMJacko has reminds me of the emergency brake equalizer return spring from my 4x4 trucks. That's 23 1/2" long. Picture of 2 of those below. One broken end on one of them.

 

TA455HO,

Thank you for the reply sir. What you have provided is what I've been seeing in my research; however, my dilemma is where does the end attach to on the z-bar. The line diagram in the manual only shows it going under the z-bar and not where it attaches. I can't find and hole of cutout anywhere where the end would fit into! Very frustrating.

Sorry I can't be of more help. My 2WD truck is an automatic so no clutch and my two 4x4 trucks do have clutches but the return spring is hooked to the fork and to a bracket that's bolted to the frame. As I looked up that base number 7542 it showed me the full part number for the 4x4 bracket which was a serviced part number. Then I noticed on the bottom of the preceding page it showed brackets for the 2WD trucks. Unfortunately, they are all not serviced - indicated by the star (*) - meaning you had to improvise. So, my hunch is the 2WD trucks should have originally had a similar bracket.

 

Man I'm getting good at resurrecting old posts but I'm assuming it's better than creating a duplicate post. I recently replaced my flywheel and clutch and when I did I just put the setup that was there back exactly like it was. So I am pretty sure my clutch is adjusted properly however the last couple of inches of travel when letting the pedal up It feels like it almost has some resistance but then releases. I hope that makes sense. So I wanted to try and find out what was causing the issue and I remembered that whenever I replaced the clutch that there are not one but two clutch return springs. They were both attached to the throw out bearing fork and then both went somewhere on the frame in different spots. I'm not sure why the prior owner had two springs on the clutch pedal but I'm pretty sure that's not how it's supposed to be. So the purpose of this reply is to see if anybody was ever able to explain exactly where the clutch return spring connects opposite of the throw out bearing fork. Also when releasing the clutch there's a definite sound of a spring releasing due to what I assume is because the spring is not in the right place and is rubbing somewhere. Now that I look at it the springs are touching so that very may well be the source of the sound. It reminds me of the sound a spring makes when opening a folding attic staircase. 😂 If anybody has any pictures of where the spring is supposed to connect that would be great. I don't want to undo what I have now until I know where it goes. Also if anyone knows the exact length of the correct spring that would be helpful as well. Thanks

Hopefully I’m posting in the correct forum to help. The anti rattle spring goes on the two holes on the fork, the belly of the spring goes in the nail of bell housing to keep it in place.
