Introduction

The motor is what converts the power stored in the battery to the physical power used to spin the cam shaft and hammer assembly. Since the motor requires the most steps and is the most difficult part to replace, it is important to keep an eye out for any cracked or broken components while taking apart your impact driver.

When you reach steps 12 and 13, the wires are soldered to the motor so a soldering iron will need to be used to disconnect them from the old motor and then reattach them to the new one.

What you need

Step 1

              Battery

Push in both push tabs on the battery at the same time.
They are located below the green housing and are in the middle on both sides of the battery.

Step 9

Remove the metal pins on each side of the inner case assembly.
It is easiest to push the pin through the opening from one side and once enough of the pin is through, grab it with the tweezers and pull it the rest of the way through.
When reassembling, make sure the pin goes in straight and makes it out the other side, rather than going in diagonally and into the inner case assembly.
