1-12. FUEL SYSTEM (CONT)
ACCELERATOR PEDAL. Depressing pedal with foot increases fuel flow and engine speed.
Releasing pedal decreases fuel flow and engine speed.
Pedal is spring loaded to re-
turn to low speed position when released.
FUEL LEVEL GAGE. Electrically operated meter type. With ignition key switch in ON
position, FUEL LEVEL gage indicates quantity of fuel remaining in fuel tank.
FUEL SHUT OFF CONTROL (ENGINE STOP). Cable connected to fuel injection pump fuel
shut off lever. When pulled out, fuel is unable to enter fuel injection pump effec-
tively stopping engine operation.
FUEL INJECTOR LINES. Fuel is routed to six fuel injectors from fuel injection pump
through rigid metal tubes.
Return (leak-off) fuel is routed through rigid metal
tubes interconnecting each fuel injector back to fuel injection pump.
1-13. COOLING SYSTEM
RADIATOR. Located at rear of loader. Engine coolant circulated through radiator giv-
ing up its heat to air stream developed by belt driven fan. Cooled coolant drawn
from bottom of radiator by water pump and discharged into lower part of cylinder
block. Radiator has oil cooler built into its bottom for cooling transmission hy-
draulic oil. Radiator cap accessible by unlocking and raising access panel located
at top rear of loader.
WATER TEMP GAGE. Indicates engine coolant temperature. Normal operating temperature
is in green zone.
