Fuel Injectors: The fuel injectors are
located on the top left side of the engine, mounted on the
cylinder head with vertical fuel injection lines. The fuel
injectors are configured with a four-hole injector nozzle
for maximum fuel flow.
i.
Fuel Filter: The fuel filter is located on the
left side of the engine, mounted on the cylinder head in
line between the fuel injection pump and the fuel tank.
The cartridge type filter element removes particles from
the fuel system.
j.
Flywheel: The flywheel is located on the
back of the engine. The flywheel is held in place on the
crankshaft with six bolts with washers. The flywheel
transmits power from the crankshaft to an attached
pump drive gearbox through the drive plate.
k.
Oil Sump: The oil sump is located on the
bottom of the engine block. Engine oil is circulated by a
gear-type oil pump driven from the rear of the front-
mounted balancer unit, located inside the oil sump. The
oil sump drain is connected to a hose for remote
draining.
l.
Fuel Injection Pump: The fuel injection
pump is located on the left side of the engine, mounted
on the back of the engine timing housing. The pump is a
mechanical governor type, configured with a D.P.A.
distributor. The fuel injection pump is connected to the
engine camshaft by a gear. The fuel injection pump
sends fuel into the engine cylinders for combustion. The
engine cold-starting induction heater is also fed by the
fuel injection pump, through the fuel filter. Fuel input is
adjusted by a transfer pressure screw on the injection
pump.

PUMP DRIVE GEARBOX.
The pump drive gearbox links the engine to the two
hydraulic propulsion pumps. A drive plate and drive
shaft connect the engine flywheel to the gearbox. An
adapter gear sleeve links the gearbox to each hydraulic
propulsion pump. The pump drive gearbox has a 1:1
ratio and is lubricated by gear oil. Two horizontal output
gears are driven by one central input gear inside the
gearbox housing. An oil drain hose and plug are
attached to the bottom of the gearbox housing.
