durability you can count on. Every day and every year.
Here are some of the heavy-duty components that make
the QSK23 the right choice for your applications.
■ Instrument Panel – Operates on 24 volts using the
■ One-Piece Cast-Iron Block – Heavy-duty design with
wide cylinder spacing for long life and excellent
rebuildability.
■ Full-Authority Electronic Controls – Sophisticated
Murphy PowerView Module J1939 communication with
a 9-pin diagnostic connection. Isolated inner panel within
an outer protective lockable box. Shutdown protection
provided through the ECM. Available on right- or left-hand
side of unit. Nema panels also available.
■ Cooling System – Heavy-duty solid-mount radiator
assembly with jacket-water, charge air cooler and fuel
cooler incorporated. Sucker or blower fan arrangements

of ferrous cast ductile iron so that expansion and
contraction won’t create excess wear.
■ Ferrous Cast Ductile Iron Pistons – For even expansion
and contraction during thermal cycles. This is the same
technology found in our 3500-hp QSK78.
■ Large-Diameter Camshaft – 105 mm of hardened
surfaces handle high load capacities. Created specifically
to work with high-pressure injection systems.
■ Rear Gear Train – Significantly reduces engine noise.
■ Seven-Bolt Cylinder Head – Delivers even clamping
force, enabling high cylinder and injector pressures.
■ Two-Stage Oil Filter – Combination full-flow and bypass
oil filter reduces maintenance costs as it extends
service intervals.
■ Clutches – Over center and spread bearing clutches
available depending on application. Provided primarily by
Twin Disc.
Cummins Industrial Warranty.
Standard And Optional Features.
S TA N D A R D
Coverage for two years or 2,000 hours of operation,
whichever occurs first, from the date of delivery of the
power unit to the first user, or from the date the unit is first
leased, rented or loaned, or when the power unit has been
operated for 50 hours, whichever comes first. If the
2,000-hour limit is exceeded during the first year,
coverage continues until the end of the first year.
Maintenance Intervals.
The less time an engine spends in service, the more
productive it is on the job. That’s why Cummins QSK23
power units only require oil and oil filter changes every
250 hours or 6 months.
