Crankshaft and main bearing journals
Note: If a crankshaft that was not originally induction hardened has been remachined, then the crankshaft must be rehardened. Use one of the process that follow for 20 hours in order to reharden the crankshaft: nitrocarburizing process and nitriding process (1) Connecting rod bearing (2) Top and bottom thrust washer thickness Standard ... 2.26 to 2.31 mm (0.089 to 0.091 inch)Oversize ... 2.45 to 2.50 mm (0.096 to 0.098 inch) (3) Main bearing Clearance for main bearings ... 0.057 to 0.117 mm (0.0022 to 0.0046 inch)Bearing width Center bearing ... 36.32 to 36.70 mm (1.430 to 1.445 inch)All other bearings ... 31.62 to 31.88 mm (1.245 to 1.255 inch)Thickness of the bearing at the center All bearings ... 2.083 to 2.086 mm (0.0820 to 0.0821 inch) (4) Crankshaft gear (5) End play of the crankshaft ... 0.05 to 0.38 mm (0.002 to 0.015 inch)Maximum permissible end play ... 0.51 mm (0.020 inch) (6) Width of the connecting rod journal ... 40.35 to 40.42 mm (1.589 to 1.591 inch)Connecting rod journal diameter of flange ... 133.27 to 133.37 mm (5.247 to 5.251 inch)Depth of recess for connecting rod bearing ... 20.22 to 20.98 mm (0.796 to 0.826 inch)Bore of recess for connecting rod bearing ... 46.96 to 46.99 mm (1.849 to 1.850 inch) Measure the connecting rod journals on the crankshaft. See the following chart for the dimensions.
