) 1. Fit the flywheel lock.

	Description	Code
1	Counter-torque	1.860.846.001

2. Undo the bolts (2a) and remove the engine flywheel (2b).

The bolts fixing the flywheel have been treated with a special agent; therefore they should be replaced each time they are removed.

Remove the flywheel lock.

Rotate the crankshaft using the tool fitted previously until the cylinder concerned is at B.D.C.2. Undo the bolts (2a) and remove the connecting rod cap (2b).3. Remove the lower connecting rod half-bearing.4. Remove the connecting rod-piston assembly.5. Remove the upper connecting rod half-bearing.Carry out the same operations to remove the pistons and connecting rods for the remaining cylinders.

Refitting ( Removing

) 1. Place the piston and connecting rod assembly (1a) in its housing complete with half-bearing using a suitable tool (1b).

For the selection of the connecting rod half-bearings, follow the procedure described previously for the main journal half-bearings. Op. 1004E20 ENGINE - DISMANTLE AND REASSEMBLE FOLLOWING OPERATION 1004E10 - WASH AND CHECK DISMANTLED PARTS - REFIT CYLINDER HEAD AND OIL SUMP - DOES NOT INCLUDE REPAIRS TO CYLINDER HEAD AND AUXILIARY UNIT.

The piston-connecting rod assemblies should be fitted in the cylinder block/crankcase so that the drain on the piston skirt is aligned with the oil jet on the engine block.

Carry out the same operations to fit the pistons and connecting rods for the remaining cylinders.

1. Test the crankpin clearance by applying plastigage to measure crankpin installation clearance.

Place the crank pin caps complete with half-bearings in their seats.

Fit the connecting rods so that the number stamped on each rod faces towardt he same side as the number stamped on the big end (inlet side).

1. Tighten the bolts (1a) to torque, using the angular tightening tool (1b).

	Fastening	Component	Ø	Value(daNm)
1a	Bolt	-	-	2.5 + 100°

	Description	Code
1b	Torque wrench	1.860.942.000

Undo the nuts 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).

	Measurement		Value
1b	Clearance between connecting rod bearings - crankpins (mm)		0.016 ÷ 0.070

If the value measured is not within the recommended figures, replace the connecting rod bearings.Carry out this test on all the crankpins, one at a time, without ever turning the crankshaft.Fit the connecting rod cap complete with half-bearing and secure it without tightening the bolts.

Fit the connecting rods so that the number stamped on each rod faces toward the same side as the number stamped on the big end (inlet side).

1. Tighten the connecting rod cap bolts (1a) to the recommended torque using the angular tightening tool (1b).
