INSPECTION

3.Cut plastigage to the same length as the width of the bearing and place it on the journal in parallel with its axis.

4.Install the crankshaft bearing cap carefully and tighten the bolts to the specified torque of 74 ± 4 N·m. 5.Carefully remove the crankshaft bearing cap. 6.Measure the width of the smashed plastigage at its widest section by using a scale printed on the plastigage bag. Standard value: 0.018 - 0.036 mm Limit: 0.1 mm

2.Using a straightedge and feeler gauge, check the block top surface for warpage. Make sure that the surface is free from gasket chips and other foreign matter. Standard value: 0.05 mm Limit: 0.1 mm 3.If the distortion is excessive, correct within the allowable limit or replace. Grinding limit: *0.2 mm *Includes/combined with cylinder head grinding.

4.Check the cylinder walls for scratches and seizure. If defects are evident, correct (bored to an oversize) or replace. 5.Using a cylinder gauge, measure the cylinder bore and cylindricality. If worn badly, correct by boring the cylinders to an oversize and replace pistons and piston rings. Measure at the points shown in the illustration. Standard value Cylinder Inside Diameter: 91.10 - 91.13 mm Cylindricality: 0.01 mm

1.Oversize pistons to be used should be determined on the basis of the largest bore cylinder. Piston size identification Size Identification mark 0.50 mm Oversize diameter 0.50 1.00 mm Oversize diameter 1.00 note Size mark is stamped on the piston top. 2.Measure the outside diameter of the piston to be used. Measure it in the thrust direction as shown. 3.Based on the measured piston Outside Diameter (OD), calculate the boring finish dimension. Boring finish dimension = Piston OD + (clearance between piston OD and cylinder) - 0.02 mm (honing margin) 4. caution To prevent distortion that may result from temperature rise during honing, bore cylinders in the order of number 2, number 4, number 6, number 1, number 3 and number 5. Bore all cylinders to the calculated boring finish dimension. 5.Hone to the final finish dimension (piston OD + clearance between piston OD and cylinder). Standard value Cylinder Inside Diameter: 91.10 - 91.13 mm Cylindricality: 0.01 mm 6.Check the clearance between the piston and cylinder. Clearance between piston and cylinder: 0.02 - 0.04 mm note When boring cylinders, finish all six cylinders to the same oversize. Do not bore only one cylinder to an oversize.
