z Assemble the bearing at the bigger end of connecting rod, and A 10 10 Section A-B after tightening the bearing cap at the specified torque, measure the diameter. 1 2 3 8 8 B EFM2049I z Crankshaft pin and bearing clearance In case that this clearance value exceeds the limit value, grind the crankshaft journal and pin and then use the undersized bearing. b) How to utilize plastic gauge z Install the crankshaft in the cylinder block and place the plastic gauge on the crankshaft journal and pin at axial direction and then after tightening the bearing cap at the specified torque and again after tearing apart the bearing cap, measure the flatten plastic gauge thickness by pick it up.
This is the oil clearance. z With the same points, the oil clearance of connecting rod also can be measured. c) End play z Assemble the crankshaft in the cylinder block. z Install the dial gauge, and measure the end play of crankshaft by pushing the crankshaft to axial direction.
