Default Throwout bearing

75 4 speed. Should the throwout bearing be touching the pressure plate at all times? I looked in side bell housing at dust boot around the fork and the bearing is turning on that pressure plate all the time. If this is not correct then do I just need to adjust my cluch? Thanks in advance

No the bearing should not ride against the pressure plate. There may be two adjustment you have to make. Adjust the rod in the engine compartment to get the proper free play and if that does not work, adjust the pivot ball on the bell housing.

Thanks for the response. I'll tackle that this weekend. Hope the lif of the bearing has not been shortened too much.

Exactly. Get it off that pressure plate and keep it off unless shifting.

Also keep from resting your foot on the clutch pedal because it causes this same thing to happen.

In fact while driving I am subconsciously pulling up on the clutch pedal just to make sure it comes all the way back up in some cars.

Having the TOB ride the PP can cut the life of the clutch in half.

Check the free play in the clutch peddle. Your AIM will have the measurement. I think it's 1 3/8 inch from the stop of the peddle to where it first engages the clutch. If the T/O bearing is engaged all the time, it will wear out in short order. Lastly, make sure you have the correct T/O bearing. Chevy made two sizes, one for the Corvette and one for passenger cars.
