The piston in the cylinders of the shovels have been changed in order to provide a piston that has an increased hardness. The harder piston will better withstand the clamping force of the bolts that hold the piston onto the rod. The new pistons are direct replacements for the former pistons.
Refer to the table for a list of the new pistons and for a list of the location of the new pistons.
