Clutch Pressure Plate Adjustment (Off-Vehicle (6.0L, 6.6L, 8.1L Only))
WARNING: This page is about a different car, the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, and 2003 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
Important:
- Use the following procedure when replacing ONLY the clutch disc. The self adjusting clutch pressure plate/cover assembly must be "reset" back to the "unworn" position in order to work properly. Failure to "reset" the cover assembly results in the inability to achieve full clutch release and clutch slippage under full torque.
- The 6.6L engine uses a "potted" style flywheel, and the cover stamping is much shorter to accommodate the flywheel, as a result to "reset" this clutch the cover MUST be evenly supported at all six bolt holes in order to keep from bending the cover and to unload the adjuster ring allowing the clutch to be "reset."
- Place the clutch pressure plate and discs, flange side down, on a press.
- Compress the pressure plate diaphragm spring fingers until tension is released from the stepped adjusting ring.
- Using 2 screwdrivers or other suitable tools, place them against 2 of the 3 stepped adjusting ring tension spring stops (1), just ahead of the adjusting ring tension springs.
- Using the screwdrivers, rotate the stepped adjusting ring counterclockwise (compressing the tension springs) until the adjusting ring steps are fully adjusted out, then continue to hold in position.
- Release the press pressure from the pressure plate diaphragm spring fingers.
- Release the adjusting ring tension spring stops.
- Remove the pressure plate and disc from the press.
