ENGINE OIL pressure indicator (2) - Normal operating pressure at 1,800 rpm and above is 50 to 70 psi (343.75 to 482.65 kPa). Minimum allowable pres- sure is 5 psi (34.48 kPa) at 650 rpm, 28 psi (193.06 kPa) at 1,800 rpm, 30 psi (206.85 kPa) at 2,000 rpm, and 35 psi (241 .35 kPa) at 2,300 rpm. Tachometer (3) and speed- ometer (4) should operate with- out excessive fluctuation or unusual noises. Engine coolant temperature in- dicator (5) - Normal operating temperature is 170°F to 185°F (77°C to 85°C); maximum allowable temperature is 230°F (110°C). Transmission oil temperature in- dicator (6) - Normal operating temperature is 165°F to 220°F (74°C to 104°C); maximum allowable temperature is 300°F (149°c). Transmission oil pressure, engine oil pressure, or tachom- eter inoperative. Any temperature gauge reads high or fails to work. 2-30
