  Connecting rod large end side clearance

  Standard
  0.14—0.36 mm {0.0056—0.0141 in}
  Maximum
  0.435 mm {0.0172 in}

2. Using a plastigauge, measure the oil clearance at the large end of the connecting rod.

  • If it is at the maximum specification or more, replace the bearing or grind the crank pin and use oversize bearings so that the specified clearance is obtained.

  Note
  • Cut the plastigauge as wide as the connecting rod bearing width, place it parallel to the crankshaft, keeping away from the oil hole.
