Periodic Inspection
PERIODIC INSPECTION
Inspect the turbocharger at regularly scheduled intervals.
Visual Inspection
1. Check for indications of oil leaks at the oil inlet
and outlet lines. Repair or replace the oil lines
as needed.
2. Inspect the air inlet connection to the
turbocharger’s turbine side for cracks or broken
hardware. Repair or replace the connection as
needed.
3. Inspect the exhaust outlet connection to the
turbocharger’s compressor side for cracks or
broken hardware. Repair or replace the
connection as needed.
Inspection of Rotor Rotation
1. With the engine cool and not operating,
manually rotate the rotor. Smooth rotation is
normal. Any catching or resistance to rotation is
an indication of abnormal operation. Replace
the turbocharger or have it repaired by a
qualified repair facility.
2. Start the engine.
3. After the engine reaches normal operating
temperature, place a stethoscope firmly against
the turbocharger case.
4. Increase the rpm gradually. A high-pitched
sound, occurring at intervals of two or three
seconds, is an indication of abnormal operation.
Replace the turbocharger or have it repaired by
a qualified repair facility.
Inspection of Rotor Play
To inspect the rotor, the turbocharger must be
removed. Inspect for maximum rotor end play and
run-out limits before reinstalling.
Removal of Turbocharger
1. Shut down the engine and allow the
turbocharger to cool. Remove the exhaust
outlet connection from the turbocharger
housing.
2. Remove the air inlet connection from the
turbocharger housing.
3. Remove the inlet and outlet oil lines from the
turbocharger. Plug the lines and ports with tape
to prevent contamination. Discard the sealing
washers and O-rings. Inspect the oil lines and
replace if damaged.
4. Remove the turbocharger mounting nuts from
the mounting studs. Lift the turbocharger from
the engine and place it on a clean, level working
surface.
5. Discard the turbocharger exhaust manifold
gasket.
