for contact with the turbocharger housing. There should NOT be any visible signs of contact between the turbine or compressor wheel and the turbocharger housing. If there is any indication of contact between the rotating wheel(s) and the housing, the turbocharger should be reconditioned or replaced.3. Check the compressor wheel for cleanliness. If only the blade side of the wheel is dirty, dirt and/or moisture is passing through the air filtering system. If oil is found only on the back side of the wheel, it indicates a possible turbocharger oil seal leak.The leak may be the result of extended engine operation at low idle or an intake air line restriction (plugged air filters), which causes the turbocharger to "slobber".4. Use a dial indicator to check end clearance on the shaft. Attach the dial indicator point on the end of turbocharger shaft. Push and pull the other end of the shaft. Note the total dial indicator reading. If the measured end play is greater than the Service Manual specifications, repair or replace the turbocharger. Measured end play less than the minimum Service Manual specifications could indicate carbon build up on the turbine wheel. The turbocharger should be disassembled for cleaning and inspection if the measured end play is less than the minimum Service Manual specifications.5. Inspect the turbine housing bore for corrosion.6. Clean the turbocharger housing with standard shop solvents and a soft bristle brush.7. Fasten the air inlet piping and the exhaust outlet piping to the turbocharger housing. Refer to the Torque Specification section in this manual for correct fastener torques.Removal and Installation
For removal and installation, or repair/replacement options of turbochargers, see your Caterpillar dealer. Refer to the Service Manual for this engine or consult your Caterpillar dealer for the procedure and specifications.Engine Mounts
Inspect
(1) Crankshaft vibration damper(2) engine mounts.Caterpillar recommends checking the engine mounts for deterioration and proper bolt torque. This will prevent excessive engine vibration caused from improper mounting. See your Service Manual or Caterpillar dealer for recommended torque values.Crankshaft Vibration Damper
Inspect
Damage to, or failure of, the crankshaft vibration damper will increase torsional vibrations and result in damage to the crankshaft and other engine components. A deteriorating vibration damper will cause excessive gear train noise at variable points in the speed range.The damper can have a visual wobble (movement to the front and rear when in rotation) on the outer ring. This does not mean a replacement is necessary since some wobble of the outer ring is normal. Mounted to the crankshaft, the damper is located behind the belt guard on the front of the engine.Rubber Damper
Your engine may be equipped with a standard rubber damper. A standard rubber damper uses a rubber mounted ring to reduce crankshaft vibration. If your engine is equipped with a rubber damper, inspect the damper for:* rubber deterioration, cracking.* movement of the rubber from its original location.Visconic Damper
Your engine may be equipped with a visconic damper. The visconic damper has a weight, located inside a fluid filled case. The weight
