c. PA-28-161, Warrior III oil pressure gauge.
The oil pressure gauge is mounted in the cluster on the instrument panel, and reads the amount of
oil pressure available at the pressurized oil passage. The cluster consists of the fuel pressure gauge and the oil
temperature gauge, along with the oil pressure gauge, mounted in a common circular instrument head. Since
the instruments are inseparable, if any one becomes defective, necessitating replacement, it will require replacing
the complete cluster. Refer to Table X-IV and Figure 10-8 for data required to calibrate the Warrior III oil
pressure gauge.
