REFITTING
I - REFITTING PREPARATION OPERATION
aparts always to be replaced: seal between ex-
haust manifold and turbocharger.
aIf there has been a fault in the turbocharger, check
that the inlet circuit assembly is not full of oil. If it is,
remove the components to be cleaned, and clean
them using a cleaning trough or a parts washer
then dry them using a compressed air nozzle.
aIf the turbocharger is being reused, clean it using a
cleaning trough or a parts washer then dry it using
a compressed air nozzle.
aUse ABRASIVE PADS (see Vehicle: Parts and
consumables for the repair) (04B, Consumables -
Products) to clean the bearing faces:
-the exhaust manifold - turbocharger,
-the turbocharger - catalytic converter,
-the turbocharger - oil return pipe.aUse SURFACE CLEANER (see Vehicle: Parts
and consumables for the repair) (04B, Consuma-
bles - Products) and clean cloths to degrease the
mating faces:
-of the exhaust manifold on the turbocharger side,
-of the turbocharger on the exhaust manifold side,
-of the turbocharger on the catalytic converter side,
-of the turbocharger on the oil return pipe side,
-of the catalytic converter on the turbocharger side.
aIn the event of replacement, torque tighten the
studs on the turbocharger (9 N.m).
II - REFITTING OPERATION FOR PART
