Operators of earthmoving and mining
equipment are facing a challenging
period. The slump in commodity prices
has had a major adverse impact on mining
operations and a further knock-on effect
on infrastructure delivery programmes.
Fleet operators who are surviving in
this challenging economic cycle have
reinforced their proactive maintenance
regime, which includes an attentive
approach to the aftermarket replacement
parts that they procure.
Andrew Yorke, operations director at
Metric Automotive Engineering, says these
enterprising fleet owners and operators
have struck a perfect balance between
the cost and quality of the parts they use
in their diesel engines. This has been
achieved by using quality aftermarket parts
that offer a more cost-effective alternative
to original parts, but meet or often exceed
original equipment manufacturers’ (OEMs)
exacting standards.
These companies do not sacrifice the
overall performance of their engines by
taking a short-sighted view on critical
diesel engine components. This is despite
procurement departments often being
incentivised to buy critical parts at the
lowest possible price and therefore com-
promising the entire diesel engine refur-
bishment cycle.
Yorke is concerned that the low cost
pirate parts do not meet the high perfor-
mance standards demanded by modern
sophisticated diesel engines that operate
in some of the most arduous environments
and conditions. They may not achieve the
expected remanufacture life and in exten-
uating circumstances may contribute to
catastrophic engine failure.
“OEMs continue to find ways of signifi-
cantly improving the horsepower of their
diesel engines. By introducing more power
into the power plant, parts are subjected to
increased stresses, increased combustion
pressures and temperatures,” says Yorke.
Metric Automotive Engineering is the
southern African distributor of IPD Parts,
which are being used by some of the
country’s leading operators of “yellow”
and “white” metal for their diesel engine
maintenance and remanufacturing require-
ments. These parts are manufactured in
a state-of-the-art factory that carries ISO
9001 certification.
However, it is IPD Parts’ ongoing invest-
ment into research and development that
continues to provide a key competitive
edge in the replacement parts market. This
is reflected by its patented new friction
welded one-piece piston. By combining
the crown and skirt, the piston is better
placed to withstand thermal loading, while
limiting plate movement and securing the
oil gallery retention plate firmly in-place.
Yorke agrees that challenging operating
conditions require very careful manage-
ment of costs, but these decisions need
to take into consideration the performance
expectations of diesel engine components,
as well as the impact that they will have
on the operation of the power plant.

IPD proves quality can be cost effective
Correct diagnostics of fuel injection systems cuts costs
IPD Parts patented a new friction welded

Incorrect diagnosis of fuel injection sys-
tems is causing fleet operators substantial
losses, and Warren Hauser, operations
manager at Reef Fuel Injection Services
(RFI), a leading accredited fuel injection
system remanufacturer in southern Africa,
is concerned that this not as apparent as it
should be to industry.
Modern fuel injection systems require that
fuel be delivered at a specific volume and
pressure. Because the tolerances for fuel
pressure variations are small, it is extremely
important that a logical series of diagnostic
tests are performed to ensure an accurate
diagnosis when problems occur.
Hauser says that it is essential that
diagnostics are conducted on professional
test equipment capable of accurately
examining the performance of fuel injectors
and injection systems. “It is only by doing
the relevant test regime on equipment that
is regularly calibrated that the customer
can be assured of an accurate report,”
says Hauser. “And it is this diagnostics
data that is used to effect reliable repair
work to injectors or complete fuel injection
systems.”
RFI is an experienced accredited fuel
injection system remanufacturer, and
through ongoing investment in equipment
and personnel, it has established its
position as one of few such companies
that can service all five leading diesel fuel
injection systems – Bosch, Caterpillar,
Delphi, Denso and Stanadyne.
RFI operates state-of-the-art electronic
diagnostic equipment which allows its
technicians to access fuel systems on
vehicle to check and diagnose. Hauser
says that it is not only access to the
latest technology that provides the quality
service, but also skilled technicians that
have extensive product knowledge. “This
facilitates the accurate diagnosis of all
fuel injection problems,” he says.
Commenting on the issue of incorrect
diagnostics, Hauser says it is a worrying
scenario and can be attributed largely to
situations where a dealer is ill equipped
and does not have skilled fuel injection
system technicians, but still does the diag-
nostic work. “These injectors are then sent
to a third party repairer, and we have had
several instances where we had to assist
customers who have found themselves in a
predicament where the fuel injection sys-
tem problem was misdiagnosed, resulting
in wasted time and money,” says Hauser.
The most important advantage that RFI
offers is it is a single source remanufactur-
er where the diagnostics and the remanu-
facture are done in the same facility. “Most
significant to the customer is the access
to rapid information, the responsiveness
shown through ongoing communication
and interaction with the fleet owner. This
not only minimises the vehicle downtime,
but through accurate diagnostics, ensures
that the correct repair work is done,” adds
Hauser.
