This premium 702422-5004 TBP439 turbocharger is designed to restore structural compression and eliminate turbo lag in Perkins 1006-series industrial diesel powerplants. Utilizing a high-nickel K18 Inconel exhaust wheel, this oil cooled turbocharger prevents premature thermal cracking under continuous prime loads.
Fleet supply and export.
Our heavy-duty Perkins industrial turbocharger is engineered to resolve power drop and high fuel consumption issues in heavy agricultural pumps, backup diesel generators, and off-highway loading machinery. Built in strict alignment with Perkins’ legendary off-highway engineering standards—trusted worldwide as the heart of every great machine for industrial diesel turbo applications—our valvetrain-driven assemblies restore original manifold boost. This replacement TBP439 (interchangeable with TBP4 series) turbo is optimized for six-cylinder Perkins industrial engines, directly replacing the OEM Perkins turbo 2674A082. Whether you are overhauling a municipal rough-terrain dumper, servicing large Perkins forklift turbo chargers, or maintaining FG Wilson generator turbo setups, our component secures original volumetric efficiency.
Continuous operation of stationary power equipment under dust-heavy, high-torque environments accelerates journal bearing clearance wear, leading to carbon build-up and localized overheating. This heat soak eventually compromises the internal dynamic oil seals, triggering excessive blue smoke, oil consumption, and turbine wheel erosion. To eliminate these common failure modes, our aftermarket Perkins turbo units feature robust, high-performance metallurgy. Cast with a premium K18 Inconel alloy turbine wheel (resisting thermal fatigue up to 750°C) and dynamically calibrated on high-speed VSR machines up to 150,000 RPM, our 702422-5004 assembly prevents shaft scoring and bearing collapse under continuous maximum exhaust loads.

This 702422-5004 TBP439 turbocharger is a direct-fit component calibrated for various stationary generator applications, material handling fleets, and legacy agricultural machinery:
| Make | Machine Model | Year Range | Engine Model | Application |
|---|---|---|---|---|
| FG Wilson | P135, P150 Prime/Standby Generators | 1995–2012 | 1006-6T (Perkins Generator Turbo) | Prime & Continuous Power Generation |
| Clark Hurth | C500 Heavy-Duty Forklifts | 1996–2008 | 1006-6T (Perkins Forklift Turbo) | Material Handling Cargo Logistics |
| Massey Ferguson | MF3600 Series Large Tractors | 1995–2005 | 1006 Series (Industrial Turbo) | Agricultural Field Tillage Work |
| Sulzer | 10-Inch High-Volume Water Pumps | 1998–2011 | 1006-6T Industrial Engine | Agricultural Irrigation & Flood Drainage |
As a specialized industrial diesel turbo manufacturer and direct alternative to a regional UK Perkins parts supplier, we provide micro-balanced turbocharging systems designed to maximize field uptime:
High oil consumption and blue exhaust smoke are typically caused by worn internal journal bearings and dynamic piston-ring seals in the center housing rotating assembly (CHRA). Under abrasive conditions or oil contamination, the oil clearance inside the bronze journal bearings increases, allowing pressurized lubricating oil to seep past the seals. On the compressor side, this oil enters the intake manifold and burns in the cylinders (producing blue smoke). On the turbine side, oil drains directly into the hot exhaust stream, causing rapid engine oil loss. Rebuilding the unit with a balanced turbo cartridge kit or replacing the entire assembly restores oil containment integrity.
The TBP439 702422-5004 is an oil cooled turbocharger, meaning it relies entirely on the flow of engine lubricating oil to cool the center housing and bearings. It does not contain internal water jackets. In contrast, water-cooled models use both oil for lubrication and engine coolant channels for heat dissipation. While oil-cooled turbos are simpler to install and maintain due to fewer hose connections, they require strict shutdown procedures. Letting the engine idle for 2-3 minutes before turning it off is essential to prevent “heat soak” from carbonizing the stagnant oil inside the hot bearing housing.
No, it is not directly interchangeable. Although many Perkins 1000-series engines share similar displacements, the 702422-5004 TBP439 is calibrated specifically for the 6-cylinder 1006-6T YD build’s exhaust gas velocities and mounting geometries. It features unique turbine/compressor wheel wheel dimensions, specific oil inlet/outlet flange spacings, and a distinct wastegate actuator calibration to maintain stable industrial power. Installing an incorrect 1004 (4-cylinder) turbocharger will cause severe exhaust flow restriction, extreme backpressure, engine overheating, and low boost under heavy loads.
To prevent dry-start bearing failure when installing a new turbo cartridge kit, the oil feed system must be thoroughly primed. First, disconnect the old oil feed pipe and inspect it for internal sludge deposits; replace it if restricted. Before bolting the oil feed line to the turbo, inject clean, fresh engine oil directly into the center housing’s oil inlet port. Spin the compressor wheel by hand several times to distribute the oil film across the bronze journals. Once fully assembled, crank the engine without starting it (by pulling the fuel shut-off solenoid fuse) to build initial oil pressure, then run at idle for 3-5 minutes.
