TURBOCHARGER INSPECTIONS CONTINUED
9. Inspect turbine housing (Figure 6, Item 2) for dents, holes, and cracks.
a. If damage is found on turbine housing, replace turbocharger (WP 0062).
b. If no damage found on turbine housing, proceed to step 10.
10. Inspect turbine (Figure 6, Item 1) for contamination, dents, holes, and cracks.
N OT E
If there is contamination, determine source of contamination, dents, holes, and cracks.
a. If damage is found on turbine, replace turbocharger (WP 0062).
b. If no damage found on turbine, proceed to step 11.
11. Inspect turbine housing (Figure 6, Item 2) and turbine (Figure 6, Item 1) for carbon and other foreign material.
a. If carbon build-up is present, replace turbocharger (WP 0062).
b. If no carbon build-up is present, proceed to step 12.
12. Rotate turbine (Figure 6, Item 1) by hand. Push assembly sideways while rotating turbine (Figure 6, Item 1).
Assembly should turn freely. Turbine should not rub turbine housing (Figure 6, Item 2).
a. If turbine does not turn freely or rubs turbine housing, replace turbocharger (WP 0062).
b. If assembly turns freely, and turbine (Figure 6, Item 1) does not rub turbine housing (Figure 6, Item 2),
proceed to step 13.
13. Inspect turbine housing (Figure 6, Item 1) and turbine (Figure 6, Item 2) for oil leakage.
a. If housing has heavy oil, replace turbocharger (WP 0062). Inspect oil drain lines. Refer to Turbocharger Oil
Supply and Oil Drain Lines in this work package.
b. If no oil is found on turbine, return to troubleshooting (WP 0019).
