Step-by-Step Process for Disassembling the Bosch 11247

Before you begin disassembling your Bosch 11247, make sure you have the right tools and workspace. A clean, well-lit area with a small container for screws and small parts will help you keep everything organized.

What You’ll Need

• Small screwdriver or a set of precision screwdrivers
• Flathead screwdriver
• Replacement parts (if necessary)
• Lubricant (for internal components)
• Compressed air (for cleaning)
• Clean cloth or rag

Step 1: Unplug the Bosch 11247

Before beginning any disassembly, ensure that your Bosch 11247 is unplugged. Safety is paramount when handling power tools, so take the extra time to ensure there is no power running through the tool during the disassembly process.

Step 2: Remove the Side Handle

The Bosch 11247 comes with a side handle to enhance control during operation. To remove it, simply loosen the side handle clamp using a screwdriver or hand by turning the adjusting knob counterclockwise. Once loose, slide the handle off the main body.

Step 3: Detach the Drill Chuck

The next step is to remove the drill chuck from the Bosch 11247. To do this:

• Locate the chuck release lever on the side of the tool.
• Press the lever to unlock the chuck.
• Twist and pull the chuck off of the shaft carefully, making sure not to damage the threads.

Step 4: Remove the Housing Screws

Using a precision screwdriver, remove the screws that secure the casing of the Bosch 11247. These screws are usually located along the sides of the housing. Once all the screws are removed, gently pull the housing apart to expose the internal components.

Step 5: Disconnect the Wiring

Once you have access to the internal wiring, disconnect the electrical connections carefully. Take note of where each wire connects, or consider taking a picture for reference when reassembling later.

Step 6: Remove the Gearbox Assembly

The Bosch 11247 features a gearbox that transfers power from the motor to the chuck. To remove the gearbox:

• Loosen any screws that hold the gearbox in place.
• Gently pull the gearbox assembly from the tool.
• Inspect the gears and lubrication for wear or damage.

Step 7: Inspect and Clean Internal Components

Once all major components are removed, take the time to inspect the internal parts of the Bosch 11247. Use compressed air to blow out any dust or debris, and clean the internal parts with a rag. Pay special attention to the motor, gears, and bearings, as these are critical to the tool’s performance.

Step 8: Reassemble the Bosch 11247

After inspecting and replacing any worn parts, begin reassembling the Bosch 11247 in reverse order:

• Reconnect the wiring carefully.
• Install the gearbox assembly and tighten all screws securely.
• Reattach the housing and tighten all screws to ensure the body is fully sealed.
• Reinstall the chuck and side handle.

Before testing the tool, ensure that all components are properly secured and that there are no loose parts.
