9.14.11 Engine Low Oil Pressure Sender
The engine oil pressure sender (1) is located on the
engine and is connected via the engine wiring harness,
bulkhead connector and cab wiring harness to the front
dash panel.
The engine oil pressure indicator is located in the
operator’s instrument cluster (3) and illuminates when
engine oil pressure is too low to properly lubricate the
engine. The warning indicator illuminates when oil
pressure is below 8.7 psi (0,6 bar).
When the engine has attained normal oil pressure, the
sender opens and the indicator on the operator’s instrument
cluster turns OFF. (Refer to Section 9.8.35, “Engine Oil
Pressure Warning Indicator Troubleshooting.”)
