Gauges and Indicators

Gauges and Indicators
Your engine may not have the same gauges or all of
the gauges that are described. For more information
about the gauge package, see the OEM information.
Gauges provide indications of engine performance.
Ensure that the gauges are in good working order.
Determine the normal operating range by observing
the gauges over a period of time.
Noticeable changes in gauge readings indicate
potential gauge or engine problems. Problems may
also be indicated by gauge readings that change
even if the readings are within specifications.
Determine and correct the cause of any significant
change in the readings. Consult your Perkins dealer
or your Perkins distributor for assistance.
