TM 5-3895-382-24 8. The bearings of the turbocharger are worn. Replace the bearings. 9. Excessive dirt exists in the compressor housing. Clean the compressor housing. 10. Carbon has collected behind the rotor of the turbine. Remove the carbon. 11. Excessive anti-corrosion fluid exists in the turbocharger. This  condition  only  exists  on  a  new  engine  which  has not been operated. Clean    the    turbocharger    in    order    to    remove    the anticorrosion fluid. 12. The high idle operates for an excessive period of time. The fuel injection pump must be repaired or replaced. 13. A   restriction   exists   in   the   bearing   housing   of   the turbocharger. The bearing housing must be repaired or replaced. Problem 4 High Consumption of Lubricating Oil Probable Cause 1. The element of the air filter is dirty. The element must be cleaned or replaced. 2. The crankcase breather is restricted. The crankcase breather (if equipped), or the tubing must be repaired or replaced. 3. The turbocharger is loose or the damps and bolts on the turbocharger are loose. Correctly   position   the   turbocharger   and   tighten   the clamps and bolts. 4. The incorrect type of lubricating oil is being used. Drain the lubricating oil.  Install the correct type and the quantity of lubricating oil. 5. The drain pipe for the lubricating oil is restricted. The drain pipe must be repaired or replaced. 6. The turbine housing is damaged or restricted. The turbine housing must be repaired or replaced. 7. The bearings of the turbocharger are worn. Replace the bearings. 8. The piston rings are worn. Replace the piston rings. 9. Lubricating oil is leaking from the supply line. The supply line must be repaired or replaced. 10. The high idle operates  for an excessive period of time. The fuel injection pump must be repaired or replaced. 11. A   restriction   exists   in   the   bearing   housing   of   the turbocharger The bearing housing must be repaired or replaced. Problem 5 Excessive Lubricating Oil At The End Of The Turbine Probable Cause 1. The crankcase breather is restricted. The crankcase breather (if equipped), or the tubing must be cleaned or replaced. 2. A restriction exists in the exhaust system. The component must be repaired or replaced. 3. The  turbocharger  is  loose  or  the  clamps  and  bolts  on the turbocharger are loose. Correctly   position   the   turbocharger   and   tighten   the clamps and bolts. 4. The drain pipe for the lubricating oil is restricted. The drain pipe must be cleaned or replaced. 5. The turbine housing is damaged or restricted. The turbine housing must be cleaned or replaced. 6. The bearings of the turbocharger are worn. Replace the bearings. 6-30
