Hello, i repaired my cordless drill and like to share it.
In my case the motor got broken, i took it out and tested it on 12 volt car battery.
and smoke came out of the motor, so it was very clear.
Order a new motor, i found mine on ebay
I did order 14.4 volt type but there is a stamp on the new motor which shows 16.6v
But it works fine and very strong!
I needed tho swap the toothgear
Step 1: Removing Old Toothgear From the Old Motor
I lifted the toothgear from the old motor with a sidecutter.
LIFTING NOT CUTTING!
Step 2: Cutting New Toothgear From New Motor.
I cutted the new toothgear from the new motor because lifting can damage the new motor
Step 3: Putting the Old Toothgear on the New Motor.
Putting the old toothgear on the new motor with a hammer
and let the bottom of the motorshaft rest on a vise.
Step 4: Solder
Solder the motor and put the drill back together, your done!!
