Introduction

I only like to use electric screwdrivers for the assembly of larger screws from larger components. This one has been used on many TV's and Radio's and just did not hold a charge any longer. I decided to get a new battery and replace the old one. Fairly easy and straight forward task. The biggest problem with this job was to find a new battery.

Black & Decker 9074 type 4 screwdriver that no longer holds a charge. Main pieces to work on for disassembly Remove the clip that holds the transmission to the body. Insert a 6mm (1/4") flat tip screwdriver underneath the clip, gently move clip upward.

Three Phillips screws 7/8" long removed. Separate the two body halves. Battery, charging port and motor are clearly seen. These are just laid into the bottom half and can be easily removed.
