If there is no improvement, inspect the truck for adequate release bearing travel.
^
It should be 11 mm or greater for full pedal travel.
^
Pedal travel at the center of the pedal pad should be 6.75" (171 mm minimum) or more, Figure 2.
9.
Release bearing travel and gear grinding noise may indicate the following concerns.
^
If the release bearing is 11 mm or greater and there is grinding of one or two gears only, the concern is probably with the transmission.
^
If all gears grind, the concern may be with the clutch and/or pilot bearing which will need replacing.
^
If the release travel is less than 11 mm, check the clutch hydraulic system for air and bleed as necessary.
10.
If the release travel is still less than 11 mm, with all of the above items eliminated, proceed as follows:
a.
Raise the hood, while an assistant operates the clutch pedal.
b.
Watch the clutch master cylinder for significant deflection.
