If the cylinders are not to be re-bored, then the cylinder glaze can be removed with a ball hone. When removing cylinder glaze with a ball hone, use a light or penetrating type oil to lubricate the hone. Do not allow the hone to run dry as this may cause excessive scoring of the cylinder bores and wear on the hone.
CAUTION
If new pistons are required, they will need to be installed in the correct relationship to the rod or engine damage can occur.

Free floating or C-clip pistons can be disassembled with conventional tools. Press fit pistons require a press to remove the piston from the rod, and a special heating device to install the new piston to the connecting rod.
All pistons will have a mark indicating the direction to the front of the engine and the must be installed into the engine in that manner. Usually a notch or arrow can be found on the top of the piston, or the letter F is cast or stamped into the piston.
