4. Measure outside diameter “Dp” of crankshaft pin journal. 5. Calculate connecting rod bearing clearance. Connecting rod bearing clearance = C − Dp Standard: 0.031 - 0.055 mm (0.0012 - 0.0022 in) I If it exceeds the limit, replace the bearing. I If crankshaft pin journal is worn or shows any abnormality, I Refer to SDS for regrinding diameter of crankshaft pin and I When regrinding crankshaft pin, do not grind fillet-roll. Selective connecting rod bearing I If either bearings or crankshaft are being replaced with new Crankshaft pin journal grade number 0 1 2 Connecting rod bearing grade 0 1 2 Identification color Grade 0: Black CONNECTING ROD AND PISTON PIN CLEARANCE Clearance (D − d): 0.025 - 0.044 mm (0.0010 - 0.0017 in) I If clearance exceeds the specifications, replace the bearing.
