The Stovebolt Site Forums The Parking Lot '60-'66 Trucks 4-speed clutch linkage

1965 C10, 230, 4-speed Muncie.

I hope someone can help. I'm putting the clutch linkage back together where it bolts to the engine and the frame. You have the push rod that pushes the clutch fork end back towards the rear of the truck which pushes the throwout bearing into the clutch springs. I don't remember the rod having a "pushrod nut", LMC part #30-0912 page 71 so I bought one. This nut isn't threaded and the rod isn't threaded....is this nut suppose to go ahead of the clutch fork to do the pushing? or is it suppose to somehow go behind the clutch fork to keep the rod from falling out of the clutch fork? Pictures would be great.

Thanks,

There is a wedge that goes on the rod & fits in the groove on the clutch fork. Some models had a nut on the other side of the the fork to keep the parts from getting lost if the rod got out of the fork. If it used this the rod would be threaded. I can't imagine the nut not having threads on it.

I have a 66 Suburban that I have recently taken this apart, and yes it does have the wedge shaped block, and no, it does not have any threads. The wedge goes on the rod with the pointed end of the block, pointing toward the rear of the vehicle. The rod goes through the fork, and the wedge fits into the vertical groove in the fork. The rod is long enough, that it will not come out of the fork, unless you have major problems.

In addition to what has been mentioned, there is a factory spring that attaches to the clutch fork and forward to the frame rail, to ensure the fork & rod do not become seperated, as well as, some resistance on the pedal. The rod has a shoulder on it and neither the rod, nor the wedge nut are threaded.

Thanks Guys!
