Description
Overview:
The Armature Assembly 110 V for Makita HR4013C Rotary SDS‐Max Hammer (part number 513886-8) is a genuine Makita replacement component for the motor's rotating core. Built with copper windings around a laminated steel core and a precision-machined commutator, it restores smooth, efficient power delivery and correct motor performance. Designed specifically for 110 V site use, it suits the HR4013C and helps maintain reliable drilling and chiselling in concrete, masonry and stone. Using the correct armature protects the tool's field coil and gearbox by keeping current draw, speed and balance within Makita specifications. This OEM assembly is a direct-fit part for users who want to resolve issues such as arcing, power loss or overheating, and to extend the service life of their SDS‐Max rotary hammer.
Key Features:
- Genuine Makita OEM armature for assured fit and compatibility with the HR4013C
- 110 V rating for safe operation with UK site transformers and equipment
- Precision-balanced rotor helps reduce vibration and electrical arcing
- Copper windings and laminated steel core for efficient power transfer
- Heat- and wear-resistant materials for durability under continuous load
- Restores lost power, speed stability and smooth motor braking
- Direct replacement design to minimise downtime during maintenance
- Built to Makita tolerances for correct alignment with bearings and gear train
- Supports long service intervals when paired with healthy brushes and commutator care
- Suitable for heavy-duty drilling and chiselling typical of SDS‐Max applications
Typical Applications:
Used when repairing a Makita HR4013C that shows symptoms such as excessive sparking, burning smell, rough running or reduced output. Common in construction, civil engineering and facilities maintenance for reinstating reliable drilling of anchor holes, through-holes and controlled chiselling in concrete, block and stone. Ideal for preventive maintenance on site tools operating from 110 V supplies.
