- Check all bearing points of the crankshaft (1) for traces of wear, cross scores, notches, blue discoloration, and damage.
For traces of wear, cross scores, notches, blue coloration and damage.
↓
Replace crankshaft (1).
- Check the contact surfaces of the crankshaft bearing shells (6) and thrust surfaces of the thrust plates (7) on the crankcase for traces of wear and damage.
In cases of traces of wear and damage.
↓
Replace crankcase and crankshaft (1).
- Check the contact surfaces of the crankshaft bearing shells (5) in the crankshafts bearing caps (2) for traces of wear and damage.
In cases of traces of wear and damage.
↓
Replace crankcase and crankshaft (1).
- Check the contact surface of the crankshaft bearing shell (5) and the thrust surfaces of the thrust plate (4) on the crankshaft bearing cap (3) for traces of wear and damage.
In cases of traces of wear and damage.
↓
Replace crankcase and crankshaft (1).
- Measure the basic bore width on the crankshaft bearing cap (3).
If the measured value lies outside the tolerance.
↓
Replace crankcase and crankshaft (1).
- Measure the diameter of the crankshaft bearing journals.
Commercially available devices/tools
Outside micrometer
If the measured values are outside the permissible tolerance range:
↓
Replace crankshaft (1).
- Measure the crankshaft bearing journal width at the thrust bearing.
Quick calipers for internal measurements
If the measured value is outside the tolerance range.
↓
Replace crankshaft (1).
- Install the crankshaft bearing cap (2) without crankshaft bearing shells (5, 6)
.
- Install the crankshaft bearing cap (3) without crankshaft bearing shells (5, 6) and without thrust plates (4, 7)
- Measure the basic bore diameter using
a dial indicator and a rapid measuring gauge for inner measurements in the directions A, B, and C.
Quick calipers for internal measurements
The measured values lie outside the tolerance.
↓
Replace crankcase and crankshaft (1).
- Remove the crankcase bearing caps (2, 3).
