Throw out mystery
About 6 months ago I had to replace the slave and master cylinder on my truck.after the install the truck wouldn't disengage the safety start switch on the clutch pedal or go into gear with the truck on. So what I ended up doing was pulling the pitman type arm on the clutch pedal off and adjusted it forward a notch. After that it would disengage the start switch and go into gear. But what I'm thinking is that maybe by adjusting it forward it's putting pressure on the clutch causing the throw out to constantly ride? Therefore causing it to wear real fast ? ...
I'm on my 3rd throw out bearing in less then a year because they disintegrate and I can't figure out why. I already did the heim joint mod so there isn't slop.
That's the only way I can't think it could be something the pedal is causing.

That sounds like a very likely conclusion to me. Generally when the clutch interlock switch won't engage, it is because the bushing or pin at the end of the master cylinder are worn out. There is a heim joint replacement out there that effectively eliminates that issue.
I would move the arm back to where it was and check out the bushing and pin. While you have the arm off is the perfect time to do the heim joint mod.

I wonder if you may have cut the rod a little too short when you did the mod and now that the arm was slipped a notch it's a little too tight. If the throw out bearing is contacting the clutch all the time that would definitely wear it out prematurely. It would be like driving with your foot on the clutch all the time.

Well I actually didn't cut the rod. , I just eliminated the stock nipple thing and put a bolt and a good washer on it.
So dunno.
Maybe the clutch fork is bent or something as well. I'm replacing the fork and the throw out bearing with ford parts.
