2) Inspection of Turbocharger
When problem occurs with the turbocharger, it could cause engine power decline, excessive discharge
of exhaust gas, outbreak of abnormal noise and excessive consumption of oil.
On-board Inspection 1.
Check the bolts and nuts foe looseness or missing
Check the intake and exhaust manifold for looseness or damage
Check the oil supply pipe and drain pipe for damages
Check the housing for crack and deterioration -
-
-
-
Inspection of turbine 2.
Remove the exhaust pipe at the opening of the turbine and check, with a lamp, the existence of
interference of housing and wheel, oil leakage and contamination (at blade edge) of foreign materials.
Interference: In case where the oil leak sign exists, even the small traces of interferences on the
turbine wheel mean, most of times, that abrasion has occurred on the journal bearing. Must
inspect after overhauling the turbocharger.
Oil Leakage: Followings are the reasons for oil leakage condition -
-
Problems in engine: In case where the oil is smeared on inner wall section of the exhaust gas
opening.
Problems in turbocharger: In case where the oil is smeared on only at the exhaust gas
outlet section. *
*
Idling for long period of time can cause oil leakage to the turbine side due to low pressure of exhaust
gas and the rotation speed of turbine wheel. Please note this is not a turbocharger problem.
Oil Drain Pipe Defect
In case where oil flow from the turbocharger sensor housing to the crank case is not smooth
would become the reason for leakage as oil builds up within the center housing. Also, oil thickens
(sludge) at high temperature and becomes the indirect reason of wheel hub section. In such case,
clogging and damage of the oil drain pipe and the pressure of blow-by gas within the crank case
must be inspected.
Damages due to Foreign Materials.
When the foreign materials get into the system, it could induce inner damage as rotating balance
of the turbocharger gets out of alignment. -

2) Camber
The angle between the center line of the tire and the vertical line when viewed from the front of the
vehicle
CamberFront-0.12˚±0.50˚
Rear-1.20˚±0.50˚
Zero camber: When the tire center line is perpendicular to the ground level ▶
Disadvantages:The axle is easy to be bent or deviated in the negative camber than in the
positive camber when load is applied on the axle.
Difficult to control due to wide load area. -
- Advantages:Better traction force due to wide load area (applicable for off-road vehicle)
Better corner driving when the vehicle makes turn as the cornering force -
- Negative camber ▶Disadvantages:Cornering force decreases as the positive camber increases when the vehicle
makes turn.
The hub bearing is worn unevenly if camber is excessive. -
- Advantages:The axle is not bent when it is loaded.
The force required to operate the steering wheel is reduced due to smaller
contact area (or load area) of the tire.
Restoring force of the steering wheel is gained (when turning the steering wheel,
the tire circles and the force to lift the frame is applied. In this case, the shock
absorber contracts and the restoration force is applied to the steering wheel.) -
-
- Positive camber: Top of the tire is tilted outward ▶
