Caterpillar C15 Industrial Engine — Turbocharger - Inspect
Maintenance
For the Caterpillar C15 Industrial Engine, from the Caterpillar owner's manual.
Applies to: Caterpillar C1.5 engine
Before you start
- Turbocharger bearing failures can cause large quantities of oil to enter the air inlet and exhaust systems. Loss of engine lubricant can result in serious engine damage.
Procedure
- Remove the exhaust outlet piping and air inlet piping from the turbocharger. Inspect piping for oil. Clean interior of pipes.
- Turn the compressor wheel and turbine wheel by hand. The assembly should turn freely.
- Inspect compressor wheel and turbine wheel for contact with the turbocharger housing. If contact is indicated, the turbocharger must be reconditioned.
- Check compressor wheel for cleanliness. Dirt on blade side indicates air filtering issue. Oil on back side may indicate a failed turbocharger oil seal.
- Use a dial indicator to check the end clearance on the shaft. If end play is greater than Service Manual specifications, repair or replace the turbocharger.
- Inspect the bore of the turbine housing for corrosion.
- Clean the turbocharger housing with standard shop solvents and a soft bristle brush.
- Fasten the air inlet piping and exhaust outlet piping to the turbocharger housing.
