Oil Pressure Check
1. CONNECT PRESSURE GAUGE
{a) Using SST, remove the pressure line from the PS
pump.
SST 09631-22020
{b) Connect the gauge side of the pressure gauge to IN
PS pump.
{c) Connect the valve side of the pressure gauge to lflt
pressure line.
{d)
Bleed the system. Start the engine and turn the wheel
fully in both directions two or three times.
{e) Check that the fluid level is correct.
2. CHECK THAT FLUIO TEMPERATURE IS AT
LEAST SO"C {176° F)
3. START ENGINE AND RUN IT AT IDLE
4. CHECK FLUID PRESSURE READING WITH VAlllt
CLOSED
Close the pressure gauge valve and observe the reading on
the gauge.
Minimum pressure: 65 kg/em' (924 psi, 6,374 kPa)
NOTE: Oo not keep the valve closed for more than
10
seconds .
If pressure is low, repair or replace the
PS
pump .
5. OPEN VALVE FULLY
6. CHECK AND RECORD PRESSURE READING AT
1,000 RPM
7. CHECK AND RECORD PRESSURE READING AT
3,000 RPM
Check that there is less than 5 kg/em' (71 psi, 490 kPa)
difference in pressure
be~en
the 1,000 rpm and
3,000
rpm checks.
If the difference is greater, repair or replace the PS pu..,
flow control valve.
