3239080 - 1028H60 piston, pin set - replace

Dismantling ( Reassembling ) 1. Remove the circlips2. Remove the pin (2a) and separate the connecting rods (2b) from the pistons (2c). 1. Remove the piston rings (1a) from the pistons using a suitable tool (1b). Reassembling ( Dismantling ) Check the alignment of the connecting rods using a suitable tool; if the connecting rods are not perfectly aligned they must be replaced.Check that the difference in weight between the pistons is within the recommended values.

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