Important: Dowel pins are used to align the flywheel and pressure plate. When removing
the pressure plate check to see if the dowel pins are rusted into the pressure plate,
if so remove, clean, and reinstall the dowel pins into the correct location(s) on
the flywheel.

Installation Procedure
- If equipped with a 6.6L or 8.1L engine,
install the clutch pressure plate and disc to the dowel pins.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
