Turn the crankshaft using the tool fitted previously.Fit the connecting rod-piston assemblies and align in accordance with the following references.1. Piston class (1a) and arrow (1b) indicating camshaft side.2. Area where the number of the matching cylinder liner is stamped.3. Exhaust (3a) on the piston skirt to be aligned with oil spray (3b). 1. Refit the piston-connecting rod assemblies (1a) in their seats with upper connecting rod bearing halves using tool (1b).

The connecting rod bearing halves may be identified as follows:upper connecting rod bearing half, connecting rod side, trimetallic and dark in colour;lower connecting rod bearing half, cap side bimetallic, light coloured with a hole.Never reverse the positioning of the connecting rod bearing halves under any circumstances.

Rotate the engine through 180° on the overhaul stand.1. Fit the calibrated wire (plastigage) for measuring the bearing clearance. 1. Refit the connecting rod cap assemblies (1a) in their seats with upper connecting rod bearing halves using tool (1b).

Undo the bolts and remove the connecting rod caps with the half-bearings fitted previously.1. Use an appropriate graduated measuring tool (1a) to measure the clearance indicated by the plastigage (1b).

Check one journal at a time, without rotating the crankshaft.

	Measurement		Value
1b	Crankshaft crankpins (mm)		0.030 ÷ 0.062

If the figure measured is outside of the tolerance, replace the connecting rod half-bearings with ones of the correct size and category.

Fit the connecting rod caps permanently by tightening the bolts as shown previously.Remove the tool.
