Line pressure/stall speed, checking: Check

Connect a tachometer so that it can be read from the driver's seat.

The air conditioning (A/C) system must be switched off.

Block all four wheels.

Start the engine.

NOTE:

Apply the parking brake. Press down hard on the brake pedal with your left foot during the test.

Move the gear shift to position D. Fully depress the accelerator pedal (AP) for a maximum of 5 seconds  . Read off the highest engine speed (RPM) and the line pressure. Compare to the table below.

NOTE:

Do not test the stall speed for more than 5 seconds  .

Gear shift position  Line pressure MPa 

B6304S/B6284T
1.30 0.2 Mpa

B6304S/B6284T
1.65 0.2 Mpa
Engine  Stall speed 
B6304S 2700
B6284T 2100 - 2400

Normal stall speed at sea level and +20°C air temperature (engine speed (RPM) reduces by 120 RPM per 1000 meters above sea level and by 50-100 RPM per 10°C above +20°C air temperature).

Repeat the tests with the gear selector in position R. Compare to the table.

If the engine speed (RPM) exceeds  the value in the table, see High stall speed  below.

If the engine speed (RPM) is below  the value in the table, see Low stall speed  below.
