11. EXPLANATION
OF COMPONENTS
11.2.4 ENGINE OIL PRESSURE GAUGE
This gauge registers the pressure at which the lubricating oil is circulated
through the engine. The pointer must register in green area (1) immediately
upon engine starting and when the engine is operated at full load speeds.
11.2.5 ILLUMINATION
LAMP
This lamp illuminates
the starting switch and the ether start switch (if
equipped)
and is applied when the work light switch is pulled out to either
position.
11.2.6 VOLTMETER
The voltmeter indicates the condition of the battery. At low idle speed, the
gauge pointer should be within the green with white stripe area (I), which
indicates a good battery charge. If the voltage drops below this area (2) the
battery should be checked.
With the engine operating above low idle speed, the pointer should be within
the upper green area (3) which is the normal operating range. If the pointer
drops below or exceeds (4) this area, the battery and/or alternator may be
at fault.
11.2.7 DRIVE TRAIN OIL TEMPERATURE
GAUGE
The gauge registers the temperature of the fluid in the drive train. After the
engine has operated sufficiently to reach a stabilized drive train temperature,
check the gauge. The pointer must be in the green range (1). If the pointer
is out of this area (2) shut down the engine and check the following:
a.
b.
;:
Restricted radiator or oil cooler core.
Low drive train oil level.
Torque converter charge pressure.
Rear main frame breather.
