4. DISASSEMBLY, INSPECTION AND REASSEMBLY OF ENGINES (5) Connecting rod (a) Appearance inspection Inspect the portion near the boundary of the chamfered portion and I-beam section of the big and small ends of the connecting rod as well as the portion near the oil hole of the bushing at the small end for cracks, defor- mation, and discoloration. (b) Twist and parallelism measurement Use a connecting rod aligner and measure the twist and bend. mm (c) Rod small end measurement Measure the pin outside diameter according to 4.4.5.(4)(a) described above. mm If the bushing is to be replaced because the oil clearance exceeds the limit, use spare part.
