SERIES 60 DEFECTIVE TURBOCHARGER

To determine if a defective turbocharger is causing excessive crankcase pressure, perform the following: ‪

NOTICE:

Ensure that the engine is not allowed to operate longer than necessary to perform the crankcase pressure test. A complete loss of crankcase oil will severely damage the engine. ‪

  1. Remove the turbocharger drain line connected to the crankcase and place the drain line into a suitable container; refer to section .
  2. Perform a crankcase pressure test.
    1. If the engine crankcase pressure is less than 3 in. H2 O, replace the turbocharger; refer to section . Shut down the engine.
    2. If the engine crankcase pressure indicates no change, check for a worn or damaged valve or cylinder kit; refer to section . Shut down the engine.

Turbocharger Replacement

Perform the following steps to replace a defective turbocharger: ‪

  1. Remove defective turbocharger from the engine; refer to section .
  2. Tag removed turbocharger for remanufacture.
  3. Install a replacement turbocharger to the engine; refer to section .
  4. Verify replacement of new turbocharger; refer to section .
Test Engine with New Turbocharger

Perform the following steps to determine if a new turbocharger resolved the excessive crankcase pressure: ‪

  1. Perform a crankcase pressure test.
    1. If the engine crankcase pressure is 3 in. H2 O (0.75 kPa) or less, no further troubleshooting is required.
    2. If the engine crankcase pressure is greater than 3 in. H2 O (0.75 kPa), check for a worn or damaged valve or cylinder kit; refer to section .
