Transmission OIL pressure in-
dicator (1) - Normal pressure is
18 to 45 psi (124.11 to
310.28 kPa) at 1,835 to 1,900
rpm and above; 10 psi (68.95
kPa) at 1,000 rpm is minimum
allowable.
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
