LOCATIONS AND DESCRIPTIONS OF MAJOR COMPONENTS - Continued
Fuel Pump
The fuel pump (Figure 3, Item 23) is attached to the flywheel housing and driven off the right side camshaft gear.
It supplies low pressure fuel to fuel inlet manifolds in cylinder heads.
Blower
The blower (Figure 3, Item 18) is mounted on top of the cylinder block. It supplies a constant volume of fresh air
per revolution to the cylinders.
Cylinder Heads
The cylinder heads (Figure 3, Item 19) are mounted on top of each cylinder side. They contain fuel manifolds,
exhaust valves, injectors, and injector and valve operating mechanisms.
Camshafts
The camshafts (Figure 3, Item 22) are located on top of each cylinder side. They actuate injector and exhaust
valve operating mechanisms.
Cylinder Block
The cylinder block (Figure 3, Item 20) is the main structural part. It provides rigidity and ensures alignment of all
load bearing assemblies.
Crankshaft
The crankshaft (Figure 3, Item 25) is attached to the bottom of the cylinder block. It transfers the engine load
through the flywheel and supplies oil to piston assemblies.
Piston and Connecting Rod Assemblies
There are three piston and connecting rod assemblies (Figure 3, Item 24) located in each side. Pistons are cooled
and lubricated by oil pressure fed up through drilled connecting rods.
Oil Pump
The oil pump (Figure 3, Item 26) is mounted inside the lower front engine cover. It pumps oil throughout the
engine for lubrication and cooling.
Bypass Valve
The bypass valve (Figure 3, Item 21) is located in the rear end plate of the blower. It increases fuel efficiency by
reducing the amount of engine power required to operate the blower at above idle speeds when the turbocharger
is supplying sufficient air flow to sustain an adequate air/fuel ratio for models 5063-5392, 5063-5393 and
5063-539L.
