Maximum raw water pressure must not exceed 1 035 kPa
(150 PSI). Minimum acceptable raw water flow at 21°C
(70°F) raw water temperature and 38°C (100°F) ambient air
temperature should be at least 227 L/min. (60 GPM) at the
2100 RPM listed rating. |
Ventilation air required for engine combustion is 802 L/sec.
(1700 CFM) at 2100 RPM rating. This is for engine air com-
bustion only and does not take into consideration additional
air required for normal room cooling.

The agency-approved horsepower ratings published are
already derated for fire pump service. The ratings show
horsepower available for driving the fire pump at standard
SAE )1349 conditions of 7521 mm (29.61 in.) Hg barometer
and 25°C (77°F) inlet air temperature (approximate 91.4 m
[300 ft.] above sea level). The only additional deration
necessary is for higher ambient temperatures and elevations
as follows: 3% for each 305 m {1000 ft.) above 91.4 m (300
ft.) and 1% for each 5.6°C (10°F) above 25°C (77°F) in
accordance with National Fire Association Pamphlet No. 20.
Bearings: Replaceable, precision type, steel backed inserts.
Seven main bearings, 146 mm (5.75 in.) diameter, Con-
necting rod bearings 96 mm (3.75 in.) diameter.
Camshaft: Dual camshafts precisely control valve and
injector timing. Lobes are induction hardened for long life.
Fourteen replaceable precision type bushings 51 mm
(2.0 in.) diameter.
Camshaft Followers: Induction hardened, roller type for
long cam and follower life.
Connecting Rods: Drop forged, I-beam section 305 mm
(12 in.) center to center length. Rifle drilled for pressure
lubrication of piston pin. Rod is tapered on piston pin end
to reduce unit pressures. Rods are removable through
Cooling System: Self adjusting belt driven centrifugal water
pump. Large volume water passages provide even flow of
coolant around cylinder liners, valves, and injectors. Dual
modulating by-pass thermostats regulate coolant
temperature. Spin-on corrosion resistors check rust and
corrosion, control acidity, and remove impurities.
Crankshaft: Fully counterweighted high tensile steel forging
with induction hardened fillets and journals.
Cylinder Block: Alloy cast iron with removable wet liners.
Cross bolt support to main bearing cap provides extra
strength and stability.
Cylinder Heads: Alloy cast iron. Each head serves three
cylinders. Drilled fuel supply and return lines. Valve seats
are replaceable corrosion resistant inserts. Valve guides
and cross head guides are replaceable inserts.
Cylinder Liners: Replaceable wet liners dissipate heat faster
than dry liners and are easily replaced without reboring
the block.
Fuel System: Cummins exclusive low pressure PT™ system
with wear compensating pump and integral dual flyweight
governor. Camshaft actuated fuel injectors give accurate
metering and timing. Fuel lines are internal drilled
passages in cylinder heads. Spin-on fuel filter.
Gear Train: Timing gears and accessory drive gears are
induction hardened helical gears driven from crankshaft
and located at front of block.
Lubrication: Large capacity gear pump provides pressure
lubrication to all bearings and oil supply for piston cool-
ing. All pressure lines are internal drilled passages in block
and heads. Oil cooler, full-flow filters, and by-pass filters
maintain oil condition and maximize oil and engine life.
Pistons: Aluminum alloy, cam ground and barrel shaped to
compensate for thermal expansion assures precise fit at
operating temperatures. CeCorr™ grooved skirt finish
provides superior lubrication. Oil cooled for rapid heat
dissipation. Teflon pads on thrust faces minimize liner
vibration and noise. Three compression and one oil ring.
Piston Pins: Full floating, tubular steel retained by snap
rings. 51 mm (2.0 in.) diameter.
Turbocharger: Two top mounted Cummins exhaust gas
driven turbochargers. Turbocharging provides more
power, improved fuel economy, altitude compensation,
and lower smoke and noise levels.
Valves: 48 mm (1.875 in.) diameter poppet type intake and
exhaust valves. Wear resistant face on exhaust valves.
Air Cleaner: Two, 381 mm (15 in.) diameter, dry type,
Belt Guard and Damper Shield: Protection from alternator,
accessory drive, and water pump belts and vibration
Coolant Pump: Belt driven, centrifugal type.
Corrosion Resistor: Fleetguard, mounted, checks rust and
corrosion, controls acidity, and removes impurities from
Electrical Equipment: 24 volt negative ground system.
24 voit starting motor; 24 volt, 18 ampere alternator;
voltage regulator; manually operable contactors; junction
box with enclosed terminal strip.

water temperature gauge, lubricating oil temperature
gauge, lubricating oil pressure gauge.
Oil Pan: Cast aluminum, center sump type, 68.1 litre
(18 U.S. gallon) capacity.
Oil Pressure Switch: Provides signal to activate alarm (not
included) tor low oil pressure.
Overspeed Switch: Mounted. Overspeed shutdown with
manual reset, stop crank contacts.
Sight Glass: Shows water level of engine at a glance; made
of heavy duty plastic for shatter protection.
Stubshaft: Mounted on flywheel.
Throttle Control: Hydraulic, with no manual override.
Vibration Damper: Compressed rubber type.
Water Jacket Heater: Mounts on right side of engine;
230 volt, 4000 watt.
