3025999 - 1028H60 piston, pin set - replace

Dismantling ( Reassembling ) 1. Remove the circlips.2. Remove the pins (2a) and separate the connecting rods (2b) from the pistons (2c).3. Remove the piston rings (3a) from the pistons using a suitable tool (3b). Reassembling ( Dismantling ) Check the alignment of the connecting rods using a suitable tool; if the connecting rod is not perfectly aligned, replace it. Check that the difference in weight between the connecting rods, complete with bearing shells, caps and bolts, is within the recommended values.

The arrows in the diagram show the areas from where material can be removed in order to equalize the weight.

	Measurement		Value
