Bearing Kit & Oil Ring (11/14/21 Motor Service Kit

Features

• Bearing kit with oil ring Replaces key rotating support components specified in the motor service kit.
• Parts-diagram referenced fitment Covers motor assembly reference parts (11, 14, 21) for accurate servicing.
• Service-ready set Ideal when the motor is stripped for overhaul, reducing the chance of re-using worn bearings.

Benefits

• Helps reduce noise and vibration: Fresh bearings can restore smoother, quieter operation during drilling.
• Improves drilling feel: Less play and roughness supports more controlled, consistent cutting.
• Protects adjacent components: Replacing worn bearings can reduce secondary wear and overheating in the drive system.

Extra Information

• This motor service kit covers bearing and oil ring components referenced as parts (11, 14, 21) on the applicable parts diagram.
• Recommended replacement signs include grinding noise, excessive heat, shaft play, vibration, or visible contamination.
• While open, inspect mating surfaces, housings and lubrication condition to avoid repeat failures.

Safety

• Disconnect the tool from the power supply before any servicing, stripping, or reassembly work.
• Wear eye, ear and dust protection when cleaning housings or removing damaged bearings.
• Use appropriate pullers/press tools to remove and install bearings—avoid slipping tools that can cause injury or damage.
• After reassembly, run the tool briefly with no load to confirm smooth rotation before returning it to full-duty drilling.
