| Measuring radial clearance |
| Special tools and workshop equipment required |
Note | t
| Do not interchange used bearings. |
| t
| Bearing shells worn down to nickel layer must be renewed. |
| –
| Remove retaining frame and clean bearing journals. |
| –
| Place Plastigage onto bearing journal or into bearing shells (length of Plastigage should correspond to width of bearing). |
| l
| The Plastigage must be positioned in the centre of the bearing shell |
| –
| Fit retaining frame and tighten to 30 Nm. Do not rotate crankshaft. |
| –
| Remove retaining frame once more. |
| –
| Compare width of Plastigage with measurement scale: |
| l
| Radial clearance (new): 0.010 ... 0.039 mm |
| l
| Wear limit (radial clearance): 0.08 mm |
