9.15.10 Engine Low Oil Pressure Switch
The engine low oil pressure switch (Fig. 9-115, 1) is
located on the engine, and is connected to the operator’s
instrument cluster via the engine wiring harness,
bulkhead connector and cab wiring harness.
Figure 9- 115 Engine Low Oil Pressure Switch
The engine oil pressure indicator is located in the
operator’s instrument cluster (Fig. 9 -116, 1) 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
switch opens and the indicator on the operator’s instrument
cluster turns OFF. (Refer to Section 9.9.6, “Engine Oil
Pressure Warning Indicator Troubleshooting.”)
