• These ratings apply at 1,800 rpm when tested under the
specific standard conditions for the specified standard.
• Power rating conditions based on standard air conditions
of 25° C (77° F) and 99 kPa (29.32 in Hg) dry barometer,
using 35° API gravity fuel having an LHV of 42 780 kJ/kg
(18,390 Btu/lb) when used at 30° C (86° F) [reference a fuel
density of 838.9 g/L (7.001 lb/gal)].
• Net power advertised is the power available when the
engine is equipped with alternator, air cleaner, muffler
and hydraulic fan drive.
• No derating required up to 3048 m (10,000 ft) altitude.
• Direct-electric, 24-volt starting system with 100 amp
alternator and four high performance maintenance-free
batteries with 1,000 cold cranking amps.
