About this product
Premium Heavy-Duty Turbocharger CHRA for JCB 3DX & 4DX Backhoe Loaders | K04 Core Assembly Maximize machine uptime on demanding worksites, eliminate black or blue exhaust smoke, and restore heavy-duty digging power with this premium Turbocharger CHRA (Center Housing Rotating Assembly) Cartridge . Specifically engineered to survive the intensive high-torque and dusty environments encountered by heavy earthmoving machinery, this precision core replacement resolves common machine failures like sluggish hydraulic responses, high-RPM engine whistling, and oil seeping directly into the air induction plumbing. This drop-in core assembly features robust internal engineering calibrated to sustain constant boost pressure across the engine's entire power band. It serves as a direct, original-quality replacement matching manufacturer part tracking references 53049700177, 53049880177, 105029021341, and 105029821341 , and JCB original equipment cross-reference 320/A6431 or 320/06179 (manufactured under premium BorgWarner / TEL Turbo Energy Limited K04 architectures). Rebuilding with a factory-balanced core allows fleet maintenance yards and construction workshops to fully overhaul high-wear internal rotating structures while cleanly retaining the intact factory cast-iron manifold housing—significantly reducing total repair expenses. Detailed Heavy Machinery & Engine Application Mapping This heavy-duty construction-grade cartridge is custom-tailored to handle relentless excavation and heavy loading cycles:
Key features
- JCB Material Handlers: Compatible wheeled loaders and industrial site configurations utilizing corresponding powertrain layouts.
- VSR High-Speed Balanced: The integrated rotor, shaft, and compressor wheel undergo meticulous high-speed dynamic balancing on computerized Vibration Sorting Rigs (VSR) at full operational limits. This process protects the heavy-duty journal bearings, eliminates machine vibrations under load, and extends component lifespan.
- Ruggedized Bearing Metallurgy: Upgraded internal thrust bearing design engineered to absorb rapid load adjustments during heavy bucket digging or intensive trenching.
- High-Nickel Turbine Construction: High-tensile shaft and turbine wheel cast to remain entirely stable without thermal distortion or cracking under continuous exhaust temperatures.
