650±50 rpm
13) Check the idle speed when loaded. (Turn the A/
C switch to “ON” and operate the compressor for at
least one minute before measurement.)
Idle speed [A/C ON and gears in neutral]:
770±50 rpm
NOTE:
Idle speed cannot be adjusted manually, because
the idle speed is automatically adjusted. If the pre-
scribed idle speed cannot be maintained, refer to

Engine Oil Pressure
MECHANICAL
6. Engine Oil Pressure
A: INSPECTION
1) Remove the oil pressure switch from cylinder
block. Pressure Switch.>
2) Connect the oil pressure gauge hose to cylinder
block.
3) Connect the ground cable to the battery.
4) Start the engine, and measure the oil pressure.
OIL PRESSURE (at oil temperature of 80°C
(176°F)):
Standard:
135 kPa (1.4 kgf/cm2, 20 psi) or more (at
600 rpm)
500 kPa (5.1 kgf/cm2, 73 psi) or more (at
5,000 rpm)
CAUTION:
•If the oil pressure is out of specification,
check oil pump, oil filter and lubrication line.
Diagnostics Table.>
•If the oil pressure warning light is turned ON
and oil pressure is in specification, replace the
oil pressure switch. SPECTION, General Diagnostics Table.>
5) After measuring the oil pressure, install the oil
pressure switch. LATION, Oil Pressure Switch.>

29) Disconnect the fuel delivery hose and evapora-
tion hose.
(1) Disconnect the connector of fuel pipe by
pushing the ST in the direction of arrow.

(2) Remove the clamp, and disconnect the
evaporation hose from the pipe.
CAUTION:
•Collect fuel from the hose into container.
•Disconnect the hose with its end wrapped
with cloth to prevent fuel from splashing.
30) Support the engine with a lifting device and
wire ropes.
31) Support the transmission with a garage jack.
CAUTION:
Doing this is very important because the trans-
mission lowers for its own weight. This work is
also of great importance for facilitating reinstal-
lation.
CAUTION:
Before removing the engine away from trans-
mission, check to be sure no work has been
overlooked.
32) Separation of engine and transmission:
(1) Remove the starter. REMOVAL, Starter.>
(2) Remove the bolts which hold upper side of
transmission to engine.
33) Install the ST to converter case.
