to maintenance guidelines, fleets can mitigate
these issues.
Spec'ing
" If you don't know the transmission make and
model, you can certainly risk damaging the transmission through the PTO being on there, " Eaton's
Bauer says.
Improperly spec'ing the PTO
can have disastrous results,
ranging from the system
running inefficiently to breaking down entirely.
" You must know the gallons
per minute, the psi, the torque,
and the horsepower and speed
[of the transmission the PTO
is being spec'd to], " Muncie's
Hart says. " With all of those,
you can determine a correct
PTO. " He also suggests reading
over the footnotes on the application page as these will aid
in fleets purchasing the right
PTO for their vehicles.

scheduled preventive maintenance is the key to
that system's longevity and functionality.
" You will need to have a regular maintenance
check of your PTO, " Hart says. " So clean around all
electrical components, make sure [the] electrical
components are working, [and] regrease the output
shaft at least one to two times a year, depending
on the use of the truck. "

Hart also recommends double-checking the
torque on every mounting bolt.
Additionally, Bauer suggests visual and auditory inspections to check for leaks, wear, and
excessive noise.
By implementing these maintenance procedures, fleets can expect maximum performance
and longer life from the PTO.

Installation
Mounting or installing the
PTO incorrectly will also lead
to problems. It's important
technicians follow the installation manual provided with
the PTO to ensure they are
properly setting the backlash
and connecting the plugs to
the right places.
Shifting
Drivers must know how to
correctly shift the PTO. If they
do not, they could wind up
clash shifting, meaning they are
trying to engage a mechanical
PTO without stopping the transmission gear first, Hart notes.
Again, an error like this could
lead to damage in the system.
ECU programming
As technology continues to
advance, the engine control
units (ECUs) in trucks have
become more complicated.
This can make installing a
PTO a bit tricky.
" When you set up a PTO ...
along with [the installation]
being correct, you also have to
program the ECU with correct
diagnostic software because if
it's not programmed correctly,
that can cause failure, it can
cause excess fuel consumption, it can cause all sorts of
havoc, " Eaton's Gulick says.
