EXTENSION HOUSING SEAL (IN VEHICLE)
REMOVAL & INSTALLATION
This seal controls transmission oil leakage around the driveshaft. Continued
failure of this seal usually indicates a worn output shaft bushing. If so, there will
be signs of the same wear on the driveshaft where it contacts the seal and
bushing. The seal is available and is fairly simple to install, with the proper tool.
1. Raise and safely support rear of t he vehicle to minimize transmission oil
loss when the driveshaft is removed.
2. Unbolt the driveshaft fr om the differential and center support bearing, if
equipped. Wrap tape around the bearing cu ps to keep them in place on
the universal joint and slide the sh aft out of the transmission.
3. Use a small pry tool to carefully pr y out the old seal. Be careful not to
insert the tool too far into the hous ing or the bushing will be damaged.
4. Use an oil seal installation tool to evenly drive the new seal into the
housing. Make sure the tool only cont acts the outer metal portion of the
seal.

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.

ENGINE & ENGINE OVERHAUL

ENGINE ELECTRICAL

ENGINE ELECTRICAL
The engine electrical system can be brok en down into three inter-related, but
distinct systems:
1. The starting system.
2. The charging system.
3. The ignition system.
BATTERY AND STARTING SYSTEM
The battery is the first link in the chai n of mechanisms which work together to
provide cranking of the autom obile engine. In most modern cars, the battery is a
lead-acid electrochemical device consis ting of six two-volt (2V) subsections
connected in series so the unit is c apable of producing approximately 12V of
electrical pressure. Each subsection, or ce ll, consists of a series of positive and
negative plates held a short distance apart in a solution of sulfuric acid and
water. The two types of plates are of di ssimilar metals. This causes a chemical
reaction to be set up, and it is this reacti on which produces current flow from the
battery when its positive and negative te rminals are connected to an electrical
appliance such as a lamp or motor.
The continued transfer of electrons would ev entually convert the sulfuric acid in
the electrolyte to water and make t he two plates identical in chemical
composition. As electrical energy is removed from the battery, its voltage output
tends to drop. Thus, measuring batte ry voltage and battery electrolyte
composition are two ways of checking the ability of the unit to supply power.
During the starting of the eng ine, electrical energy is removed from the battery.
However, if the charging circuit is in good condition and the operating conditions
are normal, the power removed from the battery will be replaced by the
generator (or alternator) which will forc e electrons back through the battery,
reversing the normal flow, and restoring the ba ttery to its original chemical state.
The battery and starting motor are linked by very heavy electrical cable\
s
designed to minimize resistance to the flow of current. Generally, the major
power supply cable that leaves the batte ry goes directly to the starter, while
other electrical system needs are supplied by a smaller cable. During the starter
operation, power flows from the battery to the starter and is grounded through
the car's frame and the batte ry's negative ground strap.
The starting motor is a specially designed, direct current electric motor capable
of producing a very great am ount of power for its size. One thing that allows the
motor to produce a great deal of power is its tremendous rotating speed. It
drives the engine through a ti ny pinion gear (attached to the starter's armature),
which drives the very large flywheel ring gear at a greatly reduced speed.
Another factor allowing it to produce so much power is that only intermittent

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 345
operation is required of it. Thus, little a
llowance for air circulation is required,
and the windings can be built into a very small space.
The starter solenoid is a magnetic dev ice which employs the small current
supplied by the starting switch circuit of the ignition switch. This magnetic action
moves a plunger which mechanically engages the starter and electrically closes
the heavy switch which connects it to t he battery. The starting switch circuit
consists of the starting switch cont ained within the ignition switch, a
transmission neutral safety switch or clutch pedal switch, and the wiring
necessary to connect these with the starter solenoid or relay.
A pinion, which is a small gear, is m ounted to a one-way drive clutch. This
clutch is splined to the starter armature shaft. When the ignition switch is moved
to the start position, the solenoid plunger slides the pinion toward the flywheel
ring gear via a collar and spring. If t he teeth on the pinion and flywheel match
properly, the pinion will engage the flywheel immediately. If the gear teeth butt
one another, the spring will be compressed and will force the gears to mesh as
soon as the starter turns far enough to a llow them to do so. As the solenoid
plunger reaches the end of it s travel, it closes the contacts that connect the
battery and starter and then the engine is cranked.
As soon as the engine star ts, the flywheel ring gear begins turning fast enough
to drive the pinion at an ex tremely high rate of speed. At this point, the one-way
clutch begins allowing the pi nion to spin faster than the starter shaft so that the
starter will not operate at excessive speed. When the i gnition switch is released
from the starter position, the solenoid is de-energized, and a spring contained
within the solenoid assembly pulls the gear out of mesh and interrupts the
current flow to the starter.
Some starters employ a separate relay, mounted away from the starter, to
switch the motor and solenoid current on and off. The relay thus replaces the
solenoid electrical switch, but does not eliminate the need for a solenoid
mounted on the starter used to mechanica lly engage the starter drive gears.
The relay is used to reduce the amount of current the starting switch must carry.
THE CHARGING SYSTEM
The automobile charging system provides electrical power for operation of the
vehicle's ignition and star ting systems and all the electrical accessories. The
battery serves as an electrical surge or storage tank, storing (in chemical form)
the energy originally pr oduced by the engine driven gen erator. The system also
provides a means of regulating alternat or output to protect the battery from
being overcharged and to avoid excess ive voltage to the accessories.
The storage battery is a chemical device in corporating parallel lead plates in a
tank containing a sulfuric acid-water solution. Adjacent plates are slightly
dissimilar, and the chemical reaction of the two dissimilar plates produces
electrical energy when the battery is connected to a load such as the starter
motor. The chemical reaction is reversible, so that when the generator i\
s
producing a voltage (electrical pressure ) greater than that produced by the

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 346
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.
