TC-8 TURBOCHARGER SYSTEM Turbocharger
TURBOCHARGER
ON-VEHICLE INSPECTION OF TURBOCHARGER
1. INSPECT INTAKE AIR SYSTEM
Check for leakage or clogging between the air cleaner and
turbocharger inlet and between the turbocharger outlet and
cylinder head.
• Clogged air cleaner .... Clean or replace the element
• Hoses collapsed or deformed .... Check each connection
and repair
• Cracks in components .... Check and replace
2. INSPECT EXHAUST SYSTEM
Check for leakage or clogging between the cylinder head
and turbocharger inlet and between the turbocharger outlet
and exhaust pipe.
• Deformed components .... Repair or replace
• Foreign material in passages .... Remove
• Leakage from components .... Repair or replace
• Cracks in components .... Check and replace
3. CHECK TURBOCHARGING PRESSURE
(a) Warm up engine.
(b) Connect a 3-way union to the intake pipe pressure
hose and install SST (turbocharger pressure gauge) to
it.
SST 09992-00241
(b) Press in the clutch pedal, then press the accelerator
pedal down as far as it will go. Measure the turbo-
charging pressure at maximum speed (4,400 rpm).
Standard pressure: 0.50-0.65 kg/cm
2
(7.1-9.2 psi, 49-64 kPa)
If the pressure is less than specification, check the intake air
and exhaust systems for leakage. If there is no leakage,
replace the turbocharger assembly.
If the pressure is above specification, check if the actuator
hose is disconnected or cracked. If not, replace the turbo-
charger assembly.
4. INSPECT IMPELLER WHEEL ROTATION
(a) Disconnect the air cleaner hose.
(b) Grasp the edge of the impeller wheel and turn it.
Check that it turns smoothly.
If it does not turn or if it turns with drag, replace the
turbocharger assembly.
