CLUTCH

UNDERSTANDING THE CLUTCH
The purpose of the clutch is to disconnect and connect engine power at the
transmission. A vehicle at rest requires a lot of engine torque to get all that
weight moving. An internal combustion engine does not develop a high starting
torque (unlike steam engines) so it must be allowed to operate without any load
until it builds up enough torque to move the vehicle. To a point, torque
increases with engine rpm. The clutch a llows the engine to build up torque by
physically disconnecting t he engine from the transmission, relieving the engine
of any load or resistance.
The transfer of engine power to the tr ansmission (the load) must be smooth and
gradual; if it weren't, driv e line components would wear out or break quickly.
This gradual power transfer is made possi ble by gradually releasing the clutch
pedal. The clutch disc and pressure plat e are the connecting link between the
engine and transmission. When the clutch pedal is released, the disc and plate
contact each other (the clutch is engag ed) physically joining the engine and
transmission. When the pedal is pushed in, the disc and plate separate (the
clutch is disengaged) disconnecting the engine from the transmission.
Most clutch assemblies consists of t he flywheel, the clutch disc, the clutch
pressure plate, the throw out bearing and fork, the actuating linkage and the
pedal. The flywheel and clutch pressure plate (driving members) are connected
to the engine crankshaft and rotate with it. The clutch disc is located between
the flywheel and pressure plate, and is splined to the transmission shaft. A
driving member is one that is attached to the engine and transfers engine power
to a driven member (clutch disc) on t he transmission shaft. A driving member
(pressure plate) rotates (drives) a driv en member (clutch disc) on contact and,
in so doing, turns the transmission shaft.
There is a circular di aphragm spring within th e pressure plate cover
(transmission side). In a relaxed state (w hen the clutch pedal is fully released)
this spring is convex; that is, it is dished outward toward the transmission.
Pushing in the clutch peda l actuates the attached linkage. Connected to the
other end of this is the throw out fork, which hold the throw out bearing. When
the clutch pedal is depre ssed, the clutch linkage pushes the fork and bearing
forward to contact the diaphragm spring of the pressure plate. The outer edges
of the spring are secured to the pressure plate and are pivoted on rings so that
when the center of the spring is compre ssed by the throw out bearing, the outer
edges bow outward and, by so doing, pu ll the pressure plate in the same
direction - away from the clutch disc. This action se parates the disc from the
plate, disengaging the clutch and allowing the transmission to be shifted into
another gear. A coil type clutch return sp ring attached to the clutch pedal arm
permits full release of the pedal. Releasing the pedal pulls the throw out bearing
away from the diaphragm spring resulting in a reversal of spring position. As
bearing pressure is gradually released from the spring center, the outer edges

DRIVELINE

DRIVESHAFT AND U-JOINTS
The U-joint is secured to the yoke in one of two ways. Dana and Cleveland
shafts use a conventional snapring to ho ld each bearing cup in the yoke. The
snapring fits into a groove located in eac h yoke end just on top of each bearing
cup. The Saginaw design shaft secures its U-joints in another way. Nylon
material is injected through a small hole in the yoke and flows along a circular
groove between the U-joint and the yoke , creating a synthetic snapring.
Disassembly of the Saginaw U-joint requi res the joint to be pressed from the
yoke. This results in damage to the be aring cups and destruction of the nylon
rings.

battery, electricity is forced into the battery
, and the battery is returned to its fully
charged state.
Alternators are used on the modern autom obiles for they are lighter, more
efficient, can rotate at higher speeds and have fewer brush problems. In an
alternator, the field rotates while al l the current produced passes only through
the stators windings. The brushes bear agains t continuous slip rings rather than
a commutator. This causes the current produced to periodically reverse the
direction of its flow. Diodes (electrica l one-way switches) block the flow of
current from traveling in t he wrong direction. A series of diodes is wired together
to permit the alternating flow of the st ator to be converted to a pulsating, but
unidirectional flow at the alternator out put. The alternator's field is wired in
series with the voltage regulator.
Please refer to Engine Performance & Tune-up for ignition system testing
procedures.

alternating current developed
within the stator windings to a direct (DC) current
at the output (BAT) terminal. Three of these diodes are negative and are
mounted flush with the end frame while t he other three are positive and are
mounted into a strip called a heat sink. The positive diodes are easily identified
as the ones within small cavities or depressions.
The alternator charging system is a negative (-) ground system which consists
of an alternator, a regulat or, a charge indicator, a storage battery and wiring
connecting the components, and fuse link wire.
The alternator is belt-driven from t he engine. Energy is supplied from the
alternator/regulator system to the rotati ng field through two brushes to two slip-
rings. The slip-rings are mounted on the rotor shaft and are connected t\
o the
field coil. This energy supplied to the ro tating field from the battery is called
excitation current and is used to init ially energize the field to begin the
generation of electricity. Once the alter nator starts to generate electricity, the
excitation current comes from its ow n output rather than the battery.
The alternator produces power in the form of alternating current. The alternating
current is rectified by 6 diodes into dire ct current. The direct current is used to
charge the battery and power the rest of the electrical system.
When the ignition key is turned ON, current flows from the battery, through the
charging system indicator light on the in strument panel, to the voltage regulator,
and to the alternator. Since the alternat or is not producing any current, the
alternator warning light comes on. When the engine is started, the alternator
begins to produce current and turns the alte rnator light off. As the alternator
turns and produces current, the current is divided in two ways: part to the
battery(to charge the battery and power the electrical components of the
vehicle), and part is returned to the alte rnator (to enable it to increase its
output). In this situation, the alternator is receiving current from the battery and
from itself. A voltage regulat or is wired into the current supply to the alternator
to prevent it from receiving too much cu rrent which would cause it to put out too
much current. Conversely, if the voltage regulator does not allow the alternator
to receive enough current, the battery will not be fully charged and will
eventually go dead.
The battery is connected to the alternator at all times, whether the ignition key is
turned ON or not. If the battery were shorted to ground, the alternator would
also be shorted. This woul d damage the alternator. To prevent this, a fuse link
is installed in the wiring between the battery and the alternator. If the battery is
shorted, the fuse link melts, protecting the alternator.
An alternator is better that a convent ional, DC shunt generator because it is
lighter and more compact, because it is designed to supply the battery and
accessory circuits through a wide range of engine speeds, and because it
eliminates the necessary maintenance of replacing brushes and servicing
commutators.

MECHANICAL ENGINE
REMOVAL & INSTALLATION
In the process of removing the engine, you will come across a number of steps
which call for the removal of a separ ate component or system, such as
"disconnect the exhaust system " or "remove the radiator." In most instances, a
detailed removal procedure can be found elsewhere in this repair guide.
It is virtually impossible to list each individual wire and hose which must be
disconnected, simply because so many different model and engine
combinations have been manufactured. Careful observation and common
sense are the best possible approaches to any repair procedure.
Removal and installation of the engine ca n be made easier if you follow these
basic points:
• If you have to drain any of the fl uids, use a suitable container.
• Always tag any wires or hoses and, if possible, the components they
came from before disconnecting them.
• Because there are so many bolts and fasteners involved, store and label
the retainers from com ponents separately in muffin pans, jars or coffee
cans. This will prevent conf usion during installation.
• After unbolting the transmission or trans axle, always make sure it is
properly supported.
• If it is necessary to disconnect t he air conditioning system, have this
service performed by a qualified tec hnician using a recovery/recycling
station. If the system does not have to be disconnected, unbolt the
compressor and set it aside.
• When unbolting the engine mounts, a lways make sure the engine is
properly supported. When removing t he engine, make sure that any
lifting devices are properly attached to the engine. It is recommended
that if your engine is supplied with lifting hooks, your lifting apparatus be
attached to them.
• Lift the engine from its compartment sl owly, checking that no hoses,
wires or other component s are still connected.
• After the engine is clear of the compar tment, place it on an engine stand
or workbench.
• After the engine has been removed, y ou can perform a partial or full
teardown of the engine using the procedur es outlined in this repair guide.
