Replace the part with a third party part.
What about a higher mileage unit where
other systems on that vehicle might be in a
failure trajectory? Another alternative is to
consider a third-party parts provider. Th ese
will-fi t parts generally have a bad reputation,
but are getting better. As with many vendors,
fl eets can fi nd reviews to help evaluate less
known or unknown parts vendors.
Rebuild
Build a new part in-house.
Many parts, especially
simple parts, can be made
less expensively than they
can be purchased.
If a fl eet has the capability
to build a spare part, this
decision should be primarily
an economic one.
Rebuild the existing part.
When the component is less
critical, a qualifi ed rebuilt
part can be a good solution.
To rebuild is to recondition a
part by cleaning, inspecting
and replacing only worn or
broken parts. Serviceable
parts are reused if they fi t
within the manufacturer’s
acceptable wear limits. Th e
quality of rebuilt components
varies from one
rebuilder to another, and
many come with only a
limited warranty.
Remanufacture
Again, how much life does
the remanufactured component
have left ? An old rule of
thumb for remanufacturing
of specialized truck bodies
was to remanufacture if the
cost is less than 50 percent of
the cost of new with greater
than 75 percent of new life.
Remanufacturing is
diff erent from rebuilding.
Th e work is done in a factory
and all the components
of the part or system are
disassembled and thoroughly
cleaned.
In addition, during remanufacturing
some components
of the remanufactured part
may be replaced with new.
For instance, new parts may
include pistons and pins,
piston rings, connecting rod
bearings, the timing gear and
chain, valve and camshaft
bearings, pushrods, valve
lift ers, gaskets and seals,
freeze plugs and oil pumps.
Additionally, cylinder heads
are cleaned and resurfaced,
cylinders are bored and valve
seats are resurfaced. Th en
they are tested, repaired,
reworked or replaced.
When all this is fi nished, the engine is
reassembled and tested using state-of-theart
computerized equipment.
With remanufacturing, the engine must
meet certain performance requirements
during oil pressure, compression and vacuum
testing.
Conclusion
Overall, there are a number of considerations
to evaluate when it comes to parts, system or
full unit replacements. Be sure to take into
account all variables and complete all of the
necessary research in order to make sure the
best decision can be made.
