4.5

Axial clearance A prior to disassembly

 CAUTION

Clearances outside the tolerance

Serious damage to engines or property can be caused by clearances outside
the tolerance and excessively worn parts.

u

Have the components assessed and, if necessary, replaced by an ABB Tur-
bocharging Service Station.

Fig. 6: Measuring axial clearance A

The axial clearance (A) must be measured prior to removal and after installation of the cart-
ridge group.

u

Measure and note axial clearance (A).
