  4. Measure the outer diameter "Dp" of each crankshaft pin journal.
  5. Calculate the connecting rod bearing clearance.

    Connecting rod bearing clearance = C - Dp 

    Standard: 0.034 - 0.059 mm (0.0013 - 0.0023 in) 

    Limit: 0.070 mm (0.0028 in) 

  6. If the calculated clearance exceeds the specified limit, replace the bearings.
  7. If the clearance cannot be adjusted within the standard of any bearing, grind the crankshaft journal and use undersized bearings.
