16 450E Backhoe Loader specifications
Engine Features
• Three-ring pistons made of lightweight, silicon/aluminum
alloy for strength and maximum thermal conductivity.
• Forged chrome/molybdenum-steel crankshaft with
crankshaft with either induction hardened or nitro
carburized journals.
• Front and rear crankshaft oil seals are “lip” type Viton and
PTFE designs featuring an integral dust lip.
• Heat resistant, silicone-chrome steel intake and STELLITE-
faced exhaust valves provide long life.
• Cylinder block is high strength, cast iron alloy of deep skirt,
monobloc design for increased strength and long life.
• Cylinder head is high strength, cast iron alloy construction
with extra duty wall and deck thickness. Intake and exhaust
ports are precision cast to promote optimum gas flow.
• High pressure, direct injection fuel system provides accurate
fuel delivery; mechanically driven fuel transfer pump.
• Dry-type axial seal air cleaner with integral precleaner,
automatic dust ejection system, and filter condition indicator.
• Direct electric, 12-volt starting and charging system with
two 880 CCA Group 31 maintenance free batteries.
• Standard glow plug starting aid system for efficient cold
weather starting.
• High contact ratio/gear train, peripheral fixed isolation top
cover and open deck block design reduce bare engine noise.
• Higher low end torque for better engine/machine
performance.

LEVEL II
Cab – Sound ANSI/SAE J1166 Oct 98
is 83 dB(A)
Exterior Sound SAE J88 APR95 is 79 dB(A)
• The operator Equivalent Sound Pressure Level (Leq) is
83 dB(A) when “ANSI/SAE J1166 OCT 98” is used to measure
the value for an enclosed cab. This is a work cycle sound
exposure level. The cab was properly installed and maintained.
The test was conducted with the cab doors and the cab
windows closed.
• Hearing protection may be needed when the machine is
operated with an open operator station for extended periods
or in a noisy environment. Hearing protection may be needed
when the machine is operated with a cab that is not properly
maintained, or when the doors and windows are open for
extended periods or in a noisy environment.
• The average exterior sound pressure level is 79 dB(A)
when the “SAE J88 Feb 2006 – Constant Speed Moving Test”
procedure is used to measure the value for the standard
machine. The measurement was conducted under the
following conditions: distance of 15 m (49.2 ft) and “the
machine moving forward in an intermediate gear ratio”.
