It should be checked that the diametral clearance is between 0.02 - 0.06 mm for both sides.
If this condition is not fulfilled, the bushing should be replaced with another of a different thickness.
These are the thickness for the half-bearings:
- red type: 2.005 - 2.010
- blue type: 2.010 - 2.015
yellow type: 2.015 - 2.020
