The place where the clutch was made said that the clutch was out of line because there is not a lineup ring on the flywheel does that sound right to you

We took the transmission back out and the clutch throwout bearing was eat up about to pull apart and it had a groove on the inside of it took the top off of the transmission and did not find nothing that appear to be wrong what could keep eating the clutches up in this engine

Morning

are you the driver of the truck ??

could be that foot resting on the pedal

and T/O bearing always spinning

or the linkage is worn and getting false free play at the pedal

No I don't drive the truck it is in my shop for repairs and it never left the yard this time before the clutch tore up
Expert:  Wayne replied 3 months ago.

Hi

I suggest to inspect the linkage real well

for the T/O bearing
