Black and Decker JS660 Gear Box Replacement

Introduction

This guide will teach the user to replace the gearbox. The gearbox is what converts the energy of the motor into the cutting power of the saw. It looks to be hard to replace because there are many stacked metal plates covered in grease, but there is a central pin that keeps it all together. Sometimes the only fix needed is to add more grease to the gearbox.
