Clutch brake? Clutch?

It looks like the adjustment bolt is stuck "in"(hard to tell if that's it in the pic). Sometime s you have to wiggle it to get to come back out. If it is, its a quick way to burn up a clutch. Also, they need to set the distance between the release bearing and clutch brake to 1/2 ''. Then adjust the linkage until the release bearing fork is 1/8'' away from the ears on the bearing. This should give you 1-1/2- 2" of free play in your pedal.

 

Once the clutch is properly adjusted, (1/2" between bearing and brake, and 1/8" between forks and bearing), you then adjust free play. HOWEVER, once you've adjusted free play once, then you never have to adjust it again. (you're not even supposed to adjust for linkage wear, you're supposed to replace the linkage) Simply adjusting the clutch will fix the free play automatically. So in this case, he either messed up the clutch adjustment, or your linkage was adjusted incorrectly at one point in time.

With the clutch engaged,(pedal out like you're driving) crawl under there and see if you can stick a 1/2" extension between the friction faces of the brake and throwout bearing. It should just barely fit. If it won't fit, or there's a lot of space still, then it needs adjusted again. This is something you can do right now in about 30 seconds with a 1/2" extension from your socket set, and a flashlight.

 

Should never touch the linkage. Set it and forget it. All adjustments should be done on the clutch itself.

 

I had a clutch linkage break and it was Christmas season I couldn’t get the part anywhere. I made it home 1400 miles by shutting off at lights and starting in bull low. It wasn’t too difficult. In your case you have a clutch so it should be a breeze if you stop at lights in gear like we’re supposed too.

 

That’s right. The linkage May be out of whack, due to wear or even Cab mounts, motor mounts being worn. Maybe it was off for a while. Probably could use a new clutch. But I was able to adjust mine, first. then adjust the linkage for freeplay. Same as a first time new clutch adjustment. I got what seemed like a totally shot clutch to last another year. Might be able to get it working right for a while.

 

When I first got my truck, I guess someone thought adjusting the linkage was the same as adjusting the clutch. Truck had zero free play at the time as well. I mean ZERO. The clutch pedal was so tight, there's no way the clutch was getting full engagement. Once I adjusted the clutch, I had FOUR INCHES of free play!
