Problem:

This problem affects the 3054 (7BJ, 5HK, 9RM) Engines equipped with closed circuit crankcase breathers and turbocharger in the above machines.

With the closed circuit breather system, the crankcase fumes are drawn through the turbocharger and inlet manifold and into the engine. These fumes contain oil vapor, and some of this vapor can condense out in the inlet manifold, turbocharger, and hoses. This is not a problem. The system is designed to contain any oil that collects in these areas. If this oil leaks out at any joint of hose connection, it can give the false appearance of a failed turbocharger.

Solution:

Genuine turbocharger failures ususally result in:

* Blue smoke
* Noise
* Evidence of compressor or turbine blades rubbing the housings
* Damaged blades
* Excess shaft end play
* Excess radial movement of the shaft

NOTE: Because turbocharger bearings are fully floating, a good turbocharger may appear to have excess play. Compare your suspect turbocharger with a new one when deciding on the shaft movement.

Do not replace a turbocharger unless it has failed. If the turbocharger has not failed, identify the source of the oil leak and replace any joint or hose that may have been affected by the oil. Use heavy duty Caterpillar hose clips to ensure tight connections.
