the torque converter end, while the blower, water pump, governor, and fuel pump are on the left side. On the 6081 engines, these
components are reversed. Rotation of both engines is counterclockwise viewed from the torque converter end.
(2) The engine is equipped with an oil cooler, replaceable element type lubricating oil filter, fuel oil strainer, fuel ol filter, air
i
cleaner, governor, and air starting motor.
(3) Fuel is drawn from the supply tank through a strainer by a gear type fuel pump. It is then forced through the filter, the fuel
inlet manifold and into the injectors. Fuel not used is returned to the supply tank via the outlet manifold and connecting lines. Since
fuel is constantly circulating through the injectors and carry off any air in the system.
(4) Air for scavenging and combustion is supplied by a blower, which pumps air into the engine cylinders via the air box and
cylinder liner ports. All air entering the blower first passes through air cleaners.
(5) Cooling is accomplished by circulating fresh water from the cooling system through the engine water jacket by a centrifugal
pump mounted on the front end of the blower.
(6) Full pressure lubrication is supplied to all main, connecting rod and camshaft bearings, and other moving parts within the
engine. A gear type pump draws oil from the oil pan through a screen, through the full flow filter and delivers it to the oil cooler.
From the oil cooler, the oil enters a longitudinal oil gallery in the cylinder block where the supply divides, a portion entering the bypass
filter and then draining back into the oil pan, part going to the cam and balance shaft end bearings and cylinder head, and the
remainder going to the main bearings and connecting rod bearings via the drilled crankshaft.
