COUPLING GP-FLEXIBLE 4157891 - Caterpillar

are based on SAE J1128/ISO 8665 standard ambient conditions of 100 kPa (29.5 inch mercury) and 25° C (77° F). Ratings also apply at AS1501, BS5514, DIN 6271 and ISO 3046/1 standard conditions of 100 kPa (29.5 inch mercury), 27° C (81° F), and 60% relative humidity. Power is based on a 35° (16° C (61° F) fuel which has Low heat value (LHV) of 42780 kJ/kg (18390 B/lb) used at 29° C (84° F) with a density of 838.9 g/L (7.001 lb/US gal). Engine ratings may be defined as gross output ratings or as the total output capability of the engine when equipped with lubrication oil, fuel and jacket water pumps. The power to drive auxiliary applications must be deducted from the gross output to arrive at the net power available for the external (flywheel) load. Typical auxiliary applications include cooling fans, air compressors, charging alternators, marine gears, and sea water pumps.
