Liner protrusion (page 5 of 11)

Place the connecting rods and pistons in position, ensuring that :

• the piston and liner matching is maintained,
• that the connecting rod sequence 1, 2, 3, and 4, as identified during removal, is correct.

Fit the piston with the arrow marked “AV” (front) and the oil jet in the connecting rods positioned as shown in the illustration.

Fit the gudgeon pin, by hand, to secure the connecting rod to the piston, fig. II.

NOTE - Depending on the fit, it may be necessary to warm up the piston, before fitting the pin, by immersing it for a few minutes in boiling water.

Carefully fit the circlips to their grooves, fig. III.

Position the oil control ring gap as shown in fig. IV.

Stagger the gaps in the compression rings with reference to gap (a) on the oil control ring.

The mark engraved on the piston rings must face towards the piston crown.

Tighten a piston ring sleeve round the rings, fig. V.

Insert the piston/connecting rod assemblies into their liners, without turning them :

• with the arrows marked “AV” (front) on the piston crowns pointing towards the timing gear end,
• ensuring that the pistons and liners are in their correct matched assemblies.

Check that the sequence 1, 2, 3, 4 is correct.

Guide each connecting rod big-end on to its crank pin, fig. VI.

Fit the big-end caps to the correct respective connecting rods.

Tightening torque : 4 m.daN (40 Nm, 30 lbf ft).
