Overview of how to take apart a Bosch 36618 cordless drill driver. I will be taking apart the drill and cleaning bits and pieces as I go. I am not fixing or repairing any particular part of the drill. I hope you find this guid helpful!

  1. Remove the battery before any disassembly.
    • Remove the battery before any disassembly.

    • Prepare a workspace by having a clean, level surface and any required tools within reach.

  2. 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.

  3. 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!

    • The second picture is a closer up shot the side with all the electronic goodies.

  4. 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.

  5. The motor can be removed from the chuck assembly with a clockwise twist. The two red boxes in the first picture depict where the separation will occur. The second picture shows the connection on the chuck assembly side.

    • When reassembling, slotting the gear pictured to the left back into the chuck assembly can be finicky. Be patient and take your time.

  7. Here are some closeups of a few electrical connections. Picture 1: connections to the trigger assembly.

  10. 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)

Thanks Calvin for taking the time to post this. The pictures and notes were excellant. I have a question more than a comment. Does the Bosch 36618 have carbon brushes? And if so, where should I start looking for them. My old 36618 all of a sudden is hesitant to start and then has sparatic speed when the trigger is pressed.

@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.

Carbon brushes can be bought at a local hardware store like Ace or DoIt Best or TruValue or Menards or Home Depot, or here’s an Amazon link: Carbon Brushes Compatible for Makita Cb154, Motor Carbon Brush Set Replaces Makita 194986 Power Tools (2 Packs) https://www.amazon.com/dp/B07Q6D1SDJ/ref...

This Amazon link is just an example, these ARE NOT THE EXACT BRISHES NEEDED FOR THE DRILL.
