T19 tob squeal/ linkage questions

[BrianX128]

My t19 in lenny in my sig started to get the old squealing throw out bearing. It usually only does it when it's cold but sometimes if it hits a good bump on the road it will do it in 4th going down the highway unless I tap the pedal.

My question is my pedal has tons of travel before it starts to effect the clutch pulling away from the flywheel so is there any harm in me putting a small shim where the pedal comes back up on the linkage to keep some pressure on things down there? It's like next to nothing maybe 1/8 of an inch of travel will shut it up. I can press it more than an inch if not more after this before it has any chance of slipping the clutch. The distance I would be shimming the pedal also isn't under much pressure at all you can push it that distance with one finger.

That 1/8” is there to keep tension off the tob. If you shim it, it will make the tob wear faster

The hydraulic clutches in these trucks are designed to have the throwout bearing running against the clutch fingers at all times, unlike the old mechanical clutches. Not having enough pressure on the bearing against the fingers can make it slip against the fingers and make a squeaking noise.

If you have a method to take some of the slack out of the system, I would try it. What I had to do to mine was to take the clutch master off, while it was still hooked up and laying on top of the engine, I took a sawzall and visegrips to hold it, and cut the rod going into the master in half. I then took a die and threaded what was left of the rod going in the master, and threaded the other piece also. It was a while back but I think it turned out to be 3/8-16 thread. I then took a long all-thread coupler nut and a regular nut, threaded them on and used the long coupler nut to put the rod back together and use the regular nut to lock it. I then was able to adjust the length of the rod by taking the end loose after the master was mounted back in place, and turn the shaft in the coupler to make it longer or shorter.

Don’t use a solid object like a block of wood, but rather use a spring on the clutch fork to hold just enough tension

I wasn’t saying it completely lifts off the pressure plate. I was going off the concept of how you’re not supposed to drive with your foot resting on the clutch pedal. That extra pressure causes increased wear.

Is there a good place to mount a small spring for this? I didn't even think of that. Might be hard to get it to hit just the right amount of tension.
