NOTE: It is imperative that the air-cleaner service
outlined In the Operators Manual be rigidly followed
because of the power losses and oil leakage Into the
Intake manifold that can be Incurred with a restricted
To ensure proper sealing of the air intake system
an air Induction test Is recommended. Consult
your authorized IH Distributor for the proper
procedure to be followed.
Intake restriction should be measured with the
engine under full load (maximum Turbocharger
Air Flow) prior to changing a Turbocharger for oil
seal leakage and always after turbocharger
measured under full load varies according to the
application but is always less than 30 In.H20.
A plugged crankcase breather element can
prevent oil drainage from the Turbocharger oil
seals to "Flood" which results in internal and
external oil leakage. CLEAN the CRANKCASE
BREATHER element and piping as required.
(Refer to Section 6).
Change the engine lubricating oil with the type
specified in the Operators Manual and at the
proper operating level. This is very important if a
Turbocharger failure has occurred.
Crank the engine without starting until oil
pressure is indicated on the oil pressure gauge.
This should provide an adequate amount of oil to
lubricate the turbocharger.
Start the engine and operate at low RPM for a
few minutes before loading engine.
NOTE: During operation, the Turbocharger should
be free from vibration or unusual noises.
NOTE: During shutdown periods or when the unit Is
being transported, the exhaust stack must be
damaging the turbine.
