The passion to restore classic
vehicles is one shared by
thousands across Australia.
Looking to recapture memories from the
past or restore old cars back to their former
glory, Aussies both young and old are
picking up the spanner and embarking on
the journey of classic car restoration.
To help those on this path, leading
Australian aftermarket restoration parts
manufacturer Rare Spares has launched
Shed Talk, an online DIY video series on
YouTube designed to provide information
about fitment and installation of Rare
Spares parts and products for your next
classic car restoration project.
For those looking to restore a classic car
or street machine with a do it yourself
attitude, Shed Talk is the best place to find
out all the information you need about
installation techniques and how to select
and fit the right Rare Spares parts.
“We recognised that there was a need
for an online video series demonstrating
the use of the Rare Spares range of
restoration parts for those undertaking DIY
projects,” Rare Spares General Manager,
David Rayner, said.
“We hope that the Shed Talk series will
answer some common questions and
problems that come up when starting a DIY
restoration project, and will inspire the
younger generation to keep these classic

Gates new accessory belt drive system
Gates, a leading supplier of drive belts and components,
has developed a new troubleshooting manual to
help you accurately diagnose accessory belt
drive component failures.
The information included in the manual will
help you detect an accessory belt drive
component that is past its service life, so you
can keep your customers on the road.
The troubleshooting manual assists you in
inspecting and diagnosing belt related problems
and includes advice on serpentine belts.
It is noted that special care should be taken
when diagnosing the EPDM constructed bets of
EPDM belts don’t necessarily exhibit
traditional signs of wear even though they might
be at or near failure.
The new troubleshooting manual illustrates
the signs of wear which indicate that a multi-
ribbed belt needs to be replaced.
The vast majority of vehicles using a multi-
ribbed belt employ an automatic belt tensioner.
If the belt tension is too low, the belt will
slip causing noise, extremely high temperatures
and premature belt wear, all of which can lead
to the poor functioning of the belt-driven
If the tension is too high, this will cause
excessive wear to the belt as well as to the belt-
Tensioners, like any other part, don’t last
Sometimes the tensioner pulley will show
signs of wear such as damage to the pulley belt
track section or grease leaking from the bearing
The rest of the tensioner is sealed to keep
moisture and contaminants out, which makes a
visual inspection difficult and unreliable.
Gates’ new troubleshooting guide explains
the signs you should look for which indicate that
the tensioner and other wear components
should be replaced.
Today’s engines are made smaller and lighter
by using more compact and lightweight
components but at the same time are becoming
More power means more strain on the
lightweight components causing more
To address this, some vehicle manufacturers
have replaced the ordinary crankshaft pulleys
with torsional vibration dampers.
Torsional vibration dampers are crankshaft
pulleys with a rubber damping element between
the two main metal parts to absorb vibrations
from the crankshaft.
A torsional vibration damper that is worn out
cannot properly dampen vibrations.
If the vibrations are not controlled, the
engine accessories can be compromised.
Follow the recommendations in Gates
troubleshooting manual as great care should be
taken when inspecting torsional vibration
dampers since the damage is not always
Seat heating, air conditioning and other
additional accessories require extra electrical
power, which causes the vehicle manufacturers
to utilise ever heavier alternators, compromising
the belt performance during deceleration of the
Drive system specialists have created the
overrunning alternator pulley which, as opposed
to a conventional solid alternator pulley, allows
the alternator to ‘free-wheel’ or ‘overrun’ every
time the engine decelerates.
Like any other part, overrunning alternator
pulleys don’t last forever and technicians will
be replacing more and more of them.
Failure of the pulley, wear and tear on the
inner spring and malfunction of the overrunning
clutch mechanism can occur.
See the Gates troubleshooting manual for
overrunning alternator pulley wear patterns.
Gates gives you complete coverage of belt
drive components to service your customers’
Gates recommends that when replacing one
of the wear parts, you replace them all.
Use Gates for genuine performance of the
accessory drive system.
