Checking turbine housing
1.
Use endoscope to check turbine housing
inside for cracks.
Note:
Cracks are only admissible in the volute in
circumferential direction.
2.
If crack exceeds max. permissible crack
length: (12V: x= 30 mm) or cracks in trans-
versal direction: Replace turbine housing.
Note:
Cracks are only admissible in the volute in
circumferential direction.
3.
If crack exceeds max. permissible crack
length: (16V / 20V: x= 10 mm) or cracks in
transversal direction: Replace turbine hous-
ing.
