Usual method is to leave the conrods attached to the crank and just remove the pistons ?

There are covers to remove so that you can gain access to the circlips that keep the gudgeon pins in place.

If he removes the circlips and 'drifts' the gudgeon pins out, the pistons are no longer attached to the con rods and can be removed from the top of the block.
