Step 2

              Remove Exterior Screws

Remove the 11 T10 Torx screws from the exterior of the drill driver.
The screw circled in orange is recessed quite far and might not be reachable with certain T10 screwdrivers.

Step 3

              Split the Drill in Half

After the 11 exterior screws are removed, pull the plastic housing pieces apart.
There are no tabs or plastic flaps holding the two pieces together. Pull straight up and the two pieces should separate easily.
Check out all that dust by the motor, that can’t be efficient!

Step 4

              Remove the Motor and Chuck Assembly

The motor and chuck assembly can be pulled up and out.
Be aware of the speed selector (first picture) which is slotted onto the motor and chuck assembly as you remove it.
Remove the electrical connections. The colors are marked on the motor so no need to remember which side is which.
The electrical connections are spade terminals with a little locking piece on the front (non flat) side of the spade. Push the lock to the back and pull the connector straight out.
What’s remaining is the motor and chuck assembly (third picture).
The chuck can be removed with a hex key, I didn’t go that far in the disassembly.

Step 6

              Remove Slide Plate

Remove the black plate on the motor by removing the two T15 Torx screws.
When reassembling, slotting the gear pictured to the left back into the chuck assembly can be finicky. Be patient and take your time.

              Miscellaneous Closeups

Picture 1: closeup of the forward, revers, and lockout assembly.
Picture 2: be cautious of this spring behind the battery receptacle, it likes to fall out.

Step 10

              Reassembly

Here’s the thoroughly cleaned and fully reassembled drill. No extra pieces, yay!
Picture 2. I relabeled the torque ring with Sharpie so that the markings were legible again.
Look at all that dust and particulates that were gunking up the drill! I’m sure the drill driver will operate more smoother and efficiently now.
Thanks for looking at my teardown! Happy fixing!

In order to replace the gearbox (part 2606200263) for new one, you must remove the chuck. I tried to but was not able. After removing the screw inside the chuck, I tried to unscrew the chuck counter clockwise without result. Do you have the trick?

Dionne,

I’m sorry I do not have any special tips or tricks, only what’s in the guide. Maybe if I would’ve seen your question four years ago I would’ve remembered more about taking this thing apart, good luck though!

Curious question: Why do all Bosch promotional pictures of drills always show only a right-side side-view? (see Google images)

@mmaterne Im pretty sure it has carbon brushes. I don’t remember explicitly since it was so long ago, but by looking at the po tires, since two wires go into the motor it’s gotta be a DC motor and I don’t know any other to use to wires with a DC motor other than brushes. And carbon is the main material type for brushes, so carbon brushes should be good for you.
