lCheck that the compressor wheel does not interfere with the
compressor housing.
lCheck that the wheel is not bent or broken.
WASTEGATE VALVE ACTUATOR
lConnect the handy pump to the actuator, and check that the rod
strokes smoothly in compliance with the following pressure.

TROUBLE DIAGNOSIS OF TURBOCHARGER
Preliminary check:
lCheck that the engine oil level is between MIN and MAX of the dipstick. (When the engine oil amount is
more than MAX, the oil flows into the inlet duct through the blow-by gas passage, and the turbocharger is
misjudged failure.)
lAsk the customer if he/she always runs the vehicle in idle engine speed to cool the oil down after driving.
lReplace the turbocharger assembly when any malfunction is found after unit inspections specified in the
table below.
lIf no malfunction is found after the unit inspections, judge that the turbocharger body has no failure. Check
the other parts again.

CAUTION:
lBe sure to clean drain plug and install with new washer.
lThe refill capacity depends on the oil temperature and drain time. Use these specifications for ref-
erence only.

OIL PUMP
lCalculate the clearance between inner rotor and oil pump hous-
ing as follows.
1. Measure the outer diameter of protruded portion of inner rotor
(Position 5)
2. Measure the inner diameter of oil pump housing with inside
micrometer (Position 6)
(Clearance) = (Inner diameter of oil pump housing) – (Outer
diameter of inner rotor)
Regulator Valve
1. Visually inspect components for wear and damage.
2. Check oil pressure regulator valve sliding surface and valve spring.
3. Coat regulator valve with engine oil. Check that it falls smoothly into the valve hole by its own weight.
If damaged, replace regulator valve set or oil pump housing.
4. Check regulator valve to oil pump housing clearance.
CAUTION:
Coat regulator valve with engine oil.
Check that it falls smoothly into the valve hole by its own
weight.
ASSEMBLY
lAssemble in the reverse order of disassembly.
lInstall the inner rotor and outer rotor with the punched marks on
the oil pump cover side.
lThe refill capacity depends on the oil temperature and drain
time. Use these specifications for reference only.
Always use the dipstick to the determine when the proper
amount of oil is in the engine.

Checking A/T FluidELS000BV
1. Warm up engine.
2. Check for fluid leakage.
3. Before driving, fluid level can be checked at fluid temperatures
of 30 to 50°C (86 to 122°F) using “COLD” range on dipstick.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check fluid level with engine idling.
d. Remove dipstick and note reading. If level is at low side of either
range, and fluid to the charging pipe.
e. Re-insert dipstick into charging pipe as far as it will go.
f. Remove dipstick and note reading. If reading is at low side of range, add fluid to the charging pipe.
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.
5. Re-check fluid level at fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on dipstick.
6. Check fluid condition.
lIf fluid is very dark or smells burned, refer to AT section for
checking operation of A/T. Flush cooling system after repair of
A/T.
lIf A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer toCO-12,
"RADIATOR",CO-15, "RADIATOR (ALUMINUM TYPE)"
