CLEANING, INSPECTION & REPAIR
Clean the Turbocharger and Related Components as
Thoroughly clean the piping connecting the air
cleaner to the Turbocharger.
Remove the air cleaner and clean inside the air
cleaner element housing. (Important to prevent
repeat Turbocharger or engine failures).
In the event of a Turbocharger failure, REPLACE
the OLD AIR CLEANER ELEMENT with a NEW
AIR CLEANER ELEMENT, because foreign
material and/or compressor wheel particles may
be embeded in the air cleaner element.
NOTE: If the air cleaner element is not changed, the
foreign material end/or particles may be drawn Into
the turbocharger compressor wheel when the engine
NOTE: Use Bendix Metal Cleaner or Gunk Hydroseal
to clean components. DO NOT use a caustic
In case of Turbocharger failure or damage to the
wheel assembly, plug the Turbocharger oil Inlet
tube and operate the engine without the
Turbocharger installed to blowout any foreign
material In the engine or manifold.
Inspect the Assembled Turbocharger as Follows:
Visually Inspect the compressor and turbine
wheels for damaged blades or evidence of wheel
contact with compressor or turbine housings.
(see Fig. a & b).
