2. INSPECTION

1) Cautions During Driving

The following lists cautions to take during test drive and on the turbocharger vehicle, which must be

considered during the operation.

It's important not to drastically increase the engine rpm starting the engine. It could make rotation at

excessive speed even before the journal bearing is lubricated and when the turbocharger rotates in

poor oil supply condition, it could cause damage of bearing seizure within few seconds.

If the engine is running radically after replacing the engine oil or oil filter brings poor oil supply

condition. To avoid this, it's necessary to start off after idling the engine for about 1 minute allowing oil

to circulate to the turbocharger after the replacement.

When the engine is stopped abruptly after driving at high speed, the turbocharger continues to rotate

in condition where the oil pressure is at '0'. In such condition, an oil film between the journal bearing

and the housing shaft journal section gets broken and this causes abrasion of the journal bearing due

to the rapid contact. The repeat of such condition significantly reduces life of the turbocharger.

Therefore, the engine should be stopped possibly in the idle condition.

After string for long period of time during winter season or in the low temperature condition where

the fluidity of engine oil declines, the engine, before being started, should be cranked to circulate oil

and must drive after checking the oil pressure is in normal condition by idling the engine for few

minutes.
