10. OIL PRESSURE INDICATOR FAILS TO REGISTER OR GIVES LOW READING
Check the crankcase oil level. Refer to LO 5-2805-258-12 for location of crankcase oil fill and level cap.
If oil is low, fill crankcase to full level as stated in LO 5-2805-258-12. If oil is not low, go on to Step 2.
Check the oil pressure indicator for broken dial, bent indicator hand, or bad connections. The oil pressure indicator
(fig. 2-3) is calibrated from 0 to 60 psi (4.2 kg per sq cm). Located at the left center of the control panel, it
indicates the engine oil pressure. The normal readings range from 20 psi (1.4 kg per sq cm) at approximately 1/4
rated speed to a maximum of 60 psi (4.2 kg per sq cm) at rated governed speed.
If the indicator is damaged, as stated above, report to organizational maintenance.
