Product Description
The Eddy Mark IV Series Brush Kit (also known as the Carbon Brush Kit) is a genuine OEM replacement part set designed specifically for the Eddy Mark IV heavy-duty electric heat gun series. This kit restores smooth, efficient motor operation in the brushed DC motor by providing fresh carbon brushes that maintain electrical contact with the armature's commutators, preventing issues like reduced power, excessive noise, sparking, or motor stalling due to worn brushes.
Key Features:
- Complete set — Includes 2 high-quality carbon brushes, 2 pressure springs, and 2 brush holder caps (the caps secure the springs and brushes in place within the holders).
- Precise OEM compatibility — Direct fit for all Eddy Mark IV models, including EP-3ULM, EP-3ULMS, EP-5ULM, EP-6ULM, EP-7ULM, and EP-1100 Plus, ensuring no modifications are needed.
- Durable materials — Carbon brushes engineered for heavy-duty, continuous, or intermittent use; designed to handle the motor's high RPM (approximately 7,200–7,500 when properly installed) and extended runtime.
- Easy access and replacement — The Mark IV features two external brush holders (one on the top side and one on the lower side of the housing), allowing straightforward inspection and swap-out with basic tools—no full disassembly required for brush changes.
- Restores performance — Replaces worn brushes that complete the electrical circuit to the motor, eliminating common wear symptoms and extending tool life significantly.
Benefits and Ideal Uses: Regular brush replacement is a simple, cost-effective way to maintain peak performance in these legendary, rugged heat guns (with their G.E. Lexan housing and UL approval). Use this kit to:
- Revive motors showing signs of brush wear after prolonged professional use.
- Achieve quiet, vibration-free operation and full airflow/heat output.
- Support preventive maintenance in high-demand environments like automotive, marine, fabrication, upholstery, electronics, HVAC, orthopedic, or industrial repair shops.
- Extend the service life of your Mark IV for tasks such as heat-shrinking tubing, paint/varnish stripping, plastic forming, adhesive activation, drying coatings, thawing materials, or general heavy-duty heating.
Pair it with other Mark IV parts—like the armature (rotor, A-1017), stator (field assembly), or blower wheel—for a complete motor refresh if needed. It's affordably priced as a manufacturer-direct essential, offering big savings over replacing the entire tool.
Note: Installation is straightforward—remove the brush holder caps, extract old brushes/springs, insert new ones with springs, and secure caps. Always unplug the tool, allow full cooling, and follow basic electrical safety practices (e.g., wear PPE, work in a ventilated area). Refer to Eddy service resources or videos for guidance on related repairs. Not compatible with other Eddy series like the VT-1100. Keep your professional-grade Mark IV running strong with this easy maintenance upgrade!
