Unscrew the Housing: Use a screwdriver to remove the screws securing the drill’s housing. Keep a small container handy for screws to prevent losing them.
-
Open the Housing: Carefully separate the two halves of the housing. Be cautious not to damage any connection wires or tabs as you do this.
Step 2: Inspecting Components
Once you have disassembled the drill, it’s time to inspect the critical components.
Check the Motor
Carefully examine the motor for signs of wear or damage. If it shows signs of burn marks or unusual sounds during operation, it might need replacing.
Examine the Battery
Check for corrosion on battery connections, as this can affect performance. If your battery is not holding a charge, it may be time for a replacement.
Assess the Chuck
Ensure that the chuck is functioning correctly. If it is loose or the grip is compromised, it may need adjustment or replacement.
Look at the Wiring
Inspect all wiring for fraying or detachment. Damaged wires can lead to performance issues and should be either repaired or replaced.
Step 3: Replacing Defective Parts
After inspection, it’s time to replace any defective parts.
-
Replacing the Motor: If you identified motor issues, it’s crucial to replace it with a compatible 20 volt brushless motor. Unscrew it, disconnect the wires, and install the new motor carefully by reversing the disassembly steps.
-
Changing the Battery: If the battery is faulty, replace it with a new 20 volt DeWalt battery. This is usually a straightforward process involving connecting the battery correctly to the wiring.
-
Replacing Wires: If any wires were damaged during your inspection, replace them with new ones. Ensure they are soldered or connected properly without any exposed wiring.
-
Repairing the Chuck: If necessary, clean any debris from the chuck’s mechanism. If it’s heavily worn, consider purchasing a replacement chuck that fits your model.
Step 4: Reassembling the Drill
Once all repairs and replacements are completed, it’s time to put everything back together.
-
Join the Housing: Carefully align the two halves of the drill housing and press them together, ensuring that all internal wiring fits correctly.
-
Secure the Screws: Using your screwdriver, reinsert and tighten all screws to ensure the housing is firmly closed. Be gentle not to overtighten.
-
Test the Chuck: Before fully reassembling, test the chuck to ensure it opens and closes as intended.
Step 5: Final Testing
Before declaring your drill ready for action, you need to conduct a thorough test.
-
Reinsert the Battery: Place the battery back into the drill and ensure it clicks into place.
-
Perform a Test Run: Pull the trigger gently to operate the drill in a safe area. Listen for unusual sounds, check for smooth operation, and monitor for any performance issues.
