Hummer H3. Manual — part 928

of 25 mm (1 in). Inspect for clutch pedal reserve by depressing the clutch pedal. Allow the clutch
disc to quit spinning and let up on the clutch pedal while listening for the clutch disc to start
spinning. The distance the pedal moved from the floor, before the clutch disc started to spin, is
the pedal reserve.

In order to determine if the clutch is properly releasing and the hydraulic system is functioning
properly:

1. Depress the clutch pedal fully to disengage the clutch.

2. Shift into a low gear, either 1st or REVERSE.

3. Slowly shift out of the gear, only to disengage the synchronizer sleeve from the speed gear

engagement teeth.

4. Let up on the pedal, to engage the clutch.

5. Depress the clutch pedal and shift back into gear.

If the clutch pedal is releasing properly, you should be able to engage the gear without grinding
after 4-5 seconds, which is the time for the clutch disc to quit spinning.
