Installing New Engine Piston

When fitting a wrist pin in piston, select a pin which cannot be pressed into the piston by hand at room temperature. Next submerge the piston in boiling water allowing the piston to remain in the water from one to two minutes, then withdraw piston, wipe out piston pin holes with a clean cloth and insert pin. If properly selected the pin can then be pushed into the piston with a slight pressure of the hand. Taking the chill out of the pin by holding it in your hand for a few seconds and then applying a light film of oil on the pin will make it easy to install.
