Removing ( Refitting ) 1. Remove the piston rings.2. Release 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).
Refitting ( Removing ) - Check the alignment of the connecting rods using suitable equipment; if it is not correct, replace the connecting rod.- Check that the weight difference between the pistons corresponds to the recommended figures.
The arrows in the diagram illustrate where material can be removed from the to equalize the weight.
