Radial clearance between the bearing shells and the main / connecting rod journals of the crankshaft, mm:
- nominal - 0.028 / 0.028;
- maximum allowable - 0.070 / 0.070.
If the gaps are higher than the maximum allowable, then the liners on the crankshaft journals should be replaced with new ones. If the crankshaft journals are worn, they are ground to the nearest repair size, while the liners should be replaced with repair ones (increased thickness).
Permissible runout on the middle neck is not more than 0.15 mm.
