Measure the diameters of the crankshaft journals that are shown in Illustration 2. This procedure measures wear and eccentricity. Measure the diameters of the connecting rod journals (5) and main journals (6) in positions (1) and (2) . Measure the diameter (A) and (B) in each position. (1) (2) Taper The difference between positions (1) and (2) must not be more than the following value. ... 0.05 mm (0.002 inch) (A) (B) Eccentricity The eccentricity must be the following value or the eccentricity must be less than the following value. ... 0.03 mm (0.001 inch) Service limit ... 0.06 mm (0.002 inch)Measure the Main Bearing Clearance

Front main bearingMeasure the bore of the main bearings in positions (1) and (2) . Measure the bore in the directions (A) and (B) in each position.Refer to "Measure Wear on the Crankshaft". Subtract the smallest diameter of the crankshaft journal from the largest main bearing bore. The remainder is the clearance between the main bearing and the crankshaft journal.Clearance Standard clearance ... 0.044 to 0.102 mm (0.0017 to 0.0040 inch) Service limit ... 0.20 mm (0.008 inch)If the measurements are outside of the tolerances, the main bearings or the crankshaft must be replaced.The end play is measured on the front main bearing journal. End play of the crankshaft ... 0.10 to 0.40 mm (0.004 to 0.016 inch) Service limit ... 0.50 mm (0.020 inch)Crankshaft Main Bearing Cap

Refer to the Specifications Module, "Cylinder Block" topic for additional information about the front crankshaft bearing. (1) Tighten the crankshaft main bearing cap bolt to the following torque. ... 52 N m (38 lb ft) (2) Upper half of bearing capOne of the halves of the crankshaft bearing has an oil groove. The half of the bearing with the oil groove is installed in the upper half of the bearing cap. (3) Lower half of the bearing cap (4) DowelTwo dowels are installed in each bearing cap in order to correctly align the two halves of the bearing cap.
