3-speed Tranny Clutch problems ?'s - The 1947 - Present Chevrolet & GMC Truck Message Board Network

yesterday, the clutch pivot arm ball stud that mounts the engine sheared off.
I happen to have an old one that isn't quite correct, alittle longer, but same dia. ball. I replaced the ball stud and readjusted the clutch with the truck off and sitting in the driveway.

when i drove it to work this morning the clutch felt fine coming out of the driveway, but i noticed everytime i hit the clutch i had to push the clutch in further and further until the point where i was stomping it into the firewall and still was having problems shifting. this is similar to what happened just before the other one sheared.

i have ordered the correct one from LMC this morning. i am wandering if there are other issues going on here. is this the sign of a clutch going bad or am i missing something?

Could it maybe be a problem with the arm?

perhaps, but what could go wrong with the arm.

i seems like something is giving, allowing full pedal travel but not full clutch travel. i adjusted the pedal 1/2" last night and it still wont fully disengage the clutch.

I was just wondering if it could be chewing up the ball. That also could have caused the first one to fail.

thats what i am afraid off. something else is wrong and causing the pivot arm to binding on the stud and shear it off.

after work i think i am going to check the bellhousing bolts. i will look at the fork and its pivot ball. i am going to pull the dust cover as well.

I've seen the arms break off of the z bar before.

Are you sure you tightened your clutch adjustment nuts though ?

Tx, if your talking about the two jamb nuts, yes their tight.

I did a thorough inspection last night and all i found was a slightly loose motor mount bolt. The problem still exsists. i am going to try taking some more slack out of it.

Could there be something going on with the fingers of the clutch itself? the clutch probably has 50K-60K mile on it.
