REMOVAL AND INSTALLATION
Dowels —Flywheel
Removal 1. NOTE: Take care not to damage the flywheel dowel holes or the surface areas around the
flywheel dowel during removal.
Remove the flywheel dowels by using a drift pin where the flywheel dowel is installed in an open
hole and a pair of locking pliers where the flywheel dowel is installed in a blind hole.
Installation 1. NOTE: Care should be taken to drive the flywheel dowel squarely into place until it is fully
seated and to not damage the surrounding surface areas.
Install all flywheel dowels by driving them into place using a brass or plastic mallet.

to block dowel is installed in an open hole and a pair of locking pliers where the flywheel
housing to block dowel is installed in a blind hole.
Installation 1. NOTE: Care should be taken to drive the flywheel housing to block dowel squarely into place

DESCRIPTION AND OPERATION
Clutch
The primary function of the clutch is to couple and uncouple engine power to the transmission upon
driver command. For additional information, refer to
Section 308 - 02 .
z The clutch is a single plate, dry friction clutch disc. The clutch disc has a splined hub (with
integral torsional dampening springs) which attaches the clutch disc to the input shaft.
z Engine output is coupled to the input shaft by the friction existing between the clutch disc
facings and the flywheel/clutch pressure plate assembly. The extent of this friction is directly
related to the composition of the facing material and the magnitude of the clamping force
exerted by the clutch pressure plate. These factors limit the amount of torque that can be
transmitted without slippage.
z The clamping force is obtained from a diaphragm spring contained within the clutch pressure
plate assembly. This force is developed during the attachment of the clutch pressure plate to
the flywheel.
z The clutch system is disengaged when the clutch pedal is depressed and engaged when the
clutch pedal is released. This displacement removes the spring load from the clutch pressure
plate and eliminates the coupling friction between the engine and the transmission.
z When the clutch pedal is depressed, a cable connected to the clutch release lever, hub and
bearing actuates the clutch pressure plate diaphragm spring, releasing pressure on the clutch
disc. This eliminates the engagement between the transmission and the engine.

1. Remove the transmission. For additional information, refer to Section 308 - 03A (T5OD) or
Section 308 - 03B (TR3650).
2. CAUTION: Loosen the bolts evenly to prevent clutch pressure plate damage.
NOTE: If the parts are to be reused, mark the clutch pressure plate and the flywheel.
Remove the bolts and remove the clutch pressure plate and the clutch disc.
Installation
NOTE: Clean the clutch pressure plate and flywheel with a commercial alcohol- based solvent so
surfaces are free from oil film.
Do not use cleaners with a petroleum base. Do not immerse the clutch pressure plate in the solvent.
1. Position the clutch disc on the flywheel. zUsing the special tool, align the clutch disc.
