Product Description
The Eddy Mark IV Heat Gun Housing – Complete Unit with Internal Bearing and Brush Holders is a premium OEM replacement assembly engineered for the Eddy Mark IV series of industrial heat guns, produced by Eddy Products in the USA. This comprehensive housing kit is designed for technicians and heavy users seeking to fully rebuild or restore older units, addressing issues like cracks, warping from prolonged heat exposure, or internal wear in high-demand environments such as automotive repair shops, manufacturing facilities, aerospace composites work, and construction sites.
As part of Eddy Products' "serviceable forever" philosophy, this unit exemplifies the brand's commitment to durability, with all components backed by a 1–2 year warranty extension when installed professionally.
This complete housing unit is not just a shell—it's a pre-assembled, ready-to-integrate module that includes the outer shell, ergonomic handle integration points, and critical internal mounting hardware for the motor assembly. It streamlines major repairs, allowing users to transfer or replace core components like the armature (rotor), field coil (stator), heating element, and wiring harness in under an hour, minimizing downtime for professional workflows.
What's Included
- Main Housing Shell: The primary outer casing, molded as a single-piece or split-design (depending on model) for seamless motor enclosure.
- Integrated Handle Assembly Mounts: Pre-drilled and contoured for attaching the pistol-grip handles (compatible with the separate Replacement Handle Set).
- Internal Bearing: A high-precision, sealed ball bearing (typically 608ZZ or equivalent size) mounted at the rear of the housing to support the armature shaft. This bearing ensures smooth, low-friction rotation of the motor at 7,200–7,500 RPM, reducing vibration and extending motor life by up to 50% in continuous-duty applications.
- Dual Brush Holders: Two precision-machined brush holder assemblies—one positioned on the top side of the housing and one on the lower side for balanced contact. Each holder includes:
- A carbon brush port (accepts standard Eddy replacement brushes).
- Pressure spring retainer for consistent commutator contact.
- Threaded cap for secure installation and easy access during maintenance. These holders are critical for the brushed DC motor's operation, forcing the carbon brushes against the armature's copper commutators to generate the electrical spark needed for rotation.
- Mounting Hardware Kit: Includes screws, nuts, washers, and clips for securing the motor field, armature, and heating element. Also features strain relief grommets for the 6-foot power cord and toggle switch mounting points.
Materials and Construction
Crafted from GE Lexan polycarbonate plastic (fiberglass-reinforced 940A blend), the housing combines lightweight resilience with industrial-grade toughness:
- Impact Resistance: Rated for 250 ft-lbs of impact energy, making it virtually indestructible—survives 10+ foot drops onto concrete without cracking, ideal for rugged job sites.
- Thermal Stability: Withstands continuous exposure to 1200°F ambient heat without deformation, thanks to its high heat deflection temperature (up to 300°F under load).
- Flame Retardancy: UL 94 V-0 rated self-extinguishing material prevents fire propagation, essential for tools operating near flammable materials like adhesives or plastics.
- Electrical Insulation: Dielectric strength exceeds 400V/mil, insulating high-voltage components (up to 1800W) and reducing shock risks.
Key Benefits and Applications
This housing unit is indispensable for restoring full functionality in Eddy Mark IV heat guns used for precision tasks like heat shrinking insulation, stripping paint, bending plastics, curing adhesives, or thawing frozen pipes—where housing integrity directly impacts motor efficiency and user safety. Standout advantages include:
- Comprehensive Rebuild Capability: Includes bearing and brush holders for a "drop-in" motor refresh, preventing costly secondary failures like armature scoring from poor alignment.
- Enhanced Motor Performance: The integrated bearing reduces friction losses by 20–30%, supporting the brushed motor's high-RPM operation for consistent 27 CFM output without overheating.
- Proven Longevity: Users report 15+ years of service post-replacement, far outpacing generic housings that warp or insulate poorly.
- Ease of Service: Designed for quick disassembly and easy installation.
