C1 (1960) Clutch issue

[Donald H.]

I can not get the push rod that connects to the clutch fork installed into the Zbar. I am having the same problem as covered in the thread in the link below. I have checked and double checked everything regarding the pedal assembly, the clutch pedal rod orientation and length, the bracket at the pedal is installed in the normal position with the clutch rod bend down (catches water). I have the standar 6 1/2" pedal travel. Correct flywheel and bellhousing. Correct Zbar assembly. However, I have the swivel connector on the fork rod screwed all the way in and I can not connect it to that side of the Zbar.

What I learned directly from David (his is the thread in the link below) was that he had his clutch plate reversed and that was causing his problem.

We took the transmission and the clutch assembly out tonight. My clutch plate was installed correctly. I don't know the clutch manufacturer (it does not look like the Luk that lots of folks recomment), but it is a cone type diaphragm that I bought from NAPA that was supposed to be correct for my 1960 per their database.

The one thing that I noticed tonight is that perhaps I have the wrong clutch fork. Again, in the link below there are pictures of the 55-62 fork and 64-81 fork. I have included picture of the fork that came out of my car. Mine appears to be more like the 64-81 fork. I have two questions:

Can anyone tell from the pictures if I have the wrong fork?

And, if I have the wrong fork will that cause the problem I am having, i.e. is the 64-81 fork bent forward more and thus not allowing me to connect the push rod?

Don I have a picture of mine I will post it as soon as I am where it is located, but off hand it does not look the same, the bend looks different but not sure it may take me until the morning.

That fork is definitely wrong. I don't have one detached to photo, but the end of the arm should turn and be pretty much parallel with the main portion of the fork.

Don. I have the exact set-up as Richard (which is post #13 in the link you posted) in my 60 which is original. I have a Luk clutch and everything adjusts like it should.

Re: C1 (1960) Clutch issue

I though it was likely wrong from the pictures I've see in other threads.

Philip, I would appreciate if you could post a picture of yours tomorrow.

Thanks,

Don

A passenger car fork is also correct & will work. Your fork is definitely wrong. Look for a plain steel fork.

55 & 56 clutch fork is definately different then 57 and later forks.

Re: C1 (1960) Clutch issue

Don, I could not find the picture I was thinking of but have one of the fork installed the bend is about 3 7/8 inch outside to outside this is appoximate. I have a Luk clutch installed diaphragm type, and it looks to be about 1 inch of thread on the adjustment left again approximate. If you need any other dimentions pictures let me know I will warm up the building and see if I can get what may help. Very cold here in the Pacific Northwest.

Thanks Philip, but it hard to tell. I think I just going to order one from Paragon. Seems from all the comments my must be incorrect.

Thanks,

Re: C1 (1960) Clutch issue

I checked the fork that came with my '62 and it appears to be the same one you have now ( 1st photo ), which is not correct. The engine and trans were out of my car when I bought it and I can't find the pushrod. I don't know what was done by the PO to make it work. The second photo is the correct fork, pt. # 3739043. I purchased that from Chevy in the mid '70's .
You can see there is over an inch difference in the heights. The last photo shows the two forks side by side.

Erich,

I get an 'unvalid attachment' message when I try to look at you photos.

Re: C1 (1960) Clutch issue

Should be working now. I had to delete the photos and reattach for some unknown reason

Thanks Erich,

Yes I can see them now. There's more of a difference that I was thinking. More than a full 1".

Re: C1 (1960) Clutch issue

Just to follow up. Here a picture of the new fork I got from Paragon, the one in the front (raw steel) and the one that came out of my car, but would not fit the new clutch. I'm pretty sure that everything will fit now.

Thanks,

Don
