Cordless Drill: Bad Vibration
If your cordless drill is experiencing bad vibration, this can be hard on the user and the drill itself. Inspect the housing, drill chuck, bearing, and gearbox. Once you have established which part is the problem, use our repair tips to fix it yourself in no time. For advice specific to your model, please refer to your owner's manual.
Bearings
The bearing supports the shaft inside the housing, allowing for rotation of the shaft. First, remove the battery then take out the screws on the end cap and separate it from the drill. Remove the screws securing the clutch/chuck assembly to the drill, then remove from the drill. Remove the rest of the screws securing the case to the housing.
Most cordless drills do not have bearings. If your does, remove the motor and transmission and separate the two from each other. Use a bearing puller to pull off the bearing off the shaft. Install the new bearing on the shaft and reassemble the motor and transmission back in the housing. Reinstall the case, clutch/chuck assembly and the rear cap.
For some drills, the bearing may be accessed by removing the end cap and using a bearing puller to remove. Reinstall a new bearing then put the cover back on...

Chucks
The chuck supports the drill bit by holding it tightly in place when you insert a bit in it and tighten down. If you are experiencing a bad vibration, check the chuck for tightness to the drill. If it is loose, it can cause a bad vibration. Tighten if loose. Next, insert a drill bit into the chuck, tighten, then try to wobble it back and forth. If there is any movement and the chuck is installed tightly on the drill, then change out the chuck. This is a very short and simple procedure.
To remove the chuck, insert the proper screwdriver into the chuck to remove the screw at the bottom. Snug the chuck against the screwdriver and loosen by turning it clockwise (this is reversed thread). Once you’ve broken the tightness of the screw, loosen the chuck and continue to remove the screw. With the screw now removed,...

Snug the chuck against the screwdriver and loosen by turning it clockwise (this is reversed thread). Once you’ve broken the tightness of the screw, loosen the chuck and continue to remove the screw. With the screw now removed, insert a big allen key into the chuck and tighten firmly, then insert a pipe over the allen key for leverage – turn counter clockwise to loosen the chuck.
A second method is to hit the allen key quickly with a hammer to loosen. Once loosened, continue to remove from the spindle. Thread the new chuck on the spindle. Next, open the chuck and insert the allen wrench and hand tighten the chuck. Reinstall the screw, remembering it is reverse thread, and tighten.

Gear Cases
The gearbox, or transmission, houses the gears for the different speeds. If a tooth (or teeth) breaks off of a gear, it can cause a bad vibration. Determining if the transmission is the cause can be a bit hard as all the rotating parts in a drill are joined together tightly. Listen for a noise coming from the transmission that may indicate a problem, such as a tooth skipping a gear. To replace the transmission, remove the battery first and then the screws on the end cap and separate from the drill. Next, remove the screws securing the clutch/chuck assembly to the drill. Remove the rest of the screws securing the case to the housing. With the case removed, you can now separate the transmission from the motor simply by pulling it away. Install the new transmission on the motor by aligning the gears up as you install it. Ensure...

Housings
The housing houses all of the internal parts of the drill and keeps them secure. Remove the case and check all of the screw and hold-downs for tightness and tighten any that are loose. Replace any hold-downs that are broken. Any of these issues will cause a vibration, if the motor and transmission are not tightened securely inside the housing. If the housing is damaged beyond repair then you can replace it. Remove the battery then remove the end cap. Take out the clutch/chuck assembly from the drill and then remove the case. Remove the motor and transmission and transfer it into the new housing. Next, take out the switch and the brushes and transfer into the new housing. You may have to lift the motor up to install the bottom brush. Now, install the case and the clutch/chuck assembly on the new housing. Reattach the end cap and snap...
