10.
The engine rpm increases too rapidly when the engine
is started.
Check the fuel injection pump for correct operation and
settings.
11.
The period of time at high idle is insufficient.
Check the fuel injection pump for correct operation and
settings.
12.
The fuel injection pump is not operating correctly.
The fuel injection pump must be repaired or replaced.
13.
The inlet valves and the exhaust vales are burned.
Replace the inlet valves and the exhaust valves.
Determine the cause of the damage to the valves.
14.
Lubricating oil is leaking from the oil supply line.
The oil supply line must be repaired or replaced.
15.
A restriction exists in the bearing housing of the
turbocharger.
The bearing housing must be repaired or replaced.
16.
A restriction exists in the lubricating oil filter.
Clean the oil filter base and the housing for the oil filter.
Check the operation of the bypass valve in the oil filter
base. Replace the oil filter.
17.
The engine stopped too soon from a high load condition.
Check the following components for correct operation or
damage:
compressor impeller of the turbocharger
coolant system
fuel injection pump
air/fuel ratio control
wastegate
valve lash
fuel injector nozzles
Problem 12
The rotating assembly of the turbocharger does not rotate
freely.
Probable Cause
1.
The element of the air filter is not sealed correctly. A
connection between the air filter and the turbocharger is
loose.
Inspect the element of the air filter and the air supply
line to the turbocharger for correct installation.
2.
A restriction exists in the tube between the air filter and
the turbocharger.
The component must be repaired or replaced.
3.
A restriction exists in the exhaust system.
The component must be repaired or replaced.
4.
The turbocharger is loose or the clamps and bolts on
the turbocharger are loose.
Correctly position the turbocharger and tighten the
damps and bolts.
5.
The flow of the lubricating oil is delayed to the
turbocharger when the engine is started. Insufficient oil
flows to the turbocharger when the engine is running.
Check the following components for correct operation:
oil pump
the engine oil bypass valve
the bypass valve in the oil filter base
oil filter
viscosity of the oil
restrictions in oil lines
6.
The lubricating oil is dirty.
Drain the lubricating oil. Install the correct type of
lubricating oil. Replace the oil filter.
7.
The incorrect type of lubricating oil is installed.
Drain the lubricating oil. Replace the oil filter. Install the
