Product Details
ISUZU RHF55V turbocharger assembly
,water-cooled 4HK1 5.2L turbocharger
,OEM 8980277723 ELF NPR75 turbo
ISUZU Turbocharger Assembly 8-98027772-3 / 8980277723 is a verified direct-fit replacement for ISUZU ELF, NPR75, NQR75, NQR90 and Nissan Atlas trucks equipped with the 4HK1-E2N 5.2L diesel engine (2006–2026 model years). This RHF55V water-cooled turbocharger is the core component of the engine intake boosting system, using exhaust gas energy to drive a turbine that rotates a coaxial compressor — significantly increasing intake air volume and engine power output while improving combustion efficiency and fuel economy.

| Feature | Benefit + Verification Signal |
|---|---|
| RHF55V Turbo Model Match | Model precisely matches original 4HK1 engine configuration, ensuring boost characteristics, response, and power output consistent with original — per Refone/RIVTRON model specification. |
| Water-Cooled + Oil-Lubricated Dual Cooling | Water-cooled housing effectively reduces turbo operating temperature; oil lubrication ensures reliable bearing lubrication at high speed and temperature, extending service life — per RIVTRON technical specification. |
| 110–140 kW Power Coverage | Adapts to the 150–190 HP power range, meeting the power demands of NPR75 / NQR75 models — per RIVTRON power data. |
| 12.6 kg Compact Lightweight Design | Net weight of 12.6 kg facilitates installation and handling while maintaining housing strength and heat dissipation performance — per B2USA net weight data. |
| Direct Replacement Design | Mounting flange, exhaust interface, and oil/water lines precisely match original — no exhaust manifold or intercooler piping modification required — per product fitment statement. |
| 12-Month Warranty | Provides reliable after-sales protection — per supplier warranty terms. |
| QC Item | Verification Method |
|---|---|
| Dynamic Balancing Test | High-speed dynamic balancing machine — verifies turbine/compressor rotor assembly balance at high speed, reducing vibration and bearing wear. |
| Housing Air Tightness Test | Air/water tightness test — verifies no cracks or leakage in turbine housing, compressor housing, and center housing. |
| Bearing Rotation Resistance Test | Manual/low-speed rotation test — verifies smooth rotor rotation without binding or abnormal noise. |
| Boost Pressure Test | Bench test — verifies boost pressure output meets design specification at set rotational speeds. |
| Appearance & Packaging Inspection | 100% visual inspection — no cracks, blowholes, or deformation; packaging meets transport requirements. |
Certification: Supplier declares products undergo factory testing. For bulk procurement, request dynamic balancing test reports and boost pressure test records from the supplier.
- Disconnect power: Disconnect the negative battery terminal to prevent electrical short circuits.
- Drain oil: Drain engine oil and replace the oil filter.
- Remove old turbo: Remove exhaust manifold connecting bolts, oil inlet/outlet lines, coolant lines, and intercooler piping; extract the old turbocharger.
- Clean related components: Clean the exhaust manifold flange surface, oil line fittings, and intercooler piping; inspect for carbon deposits or debris. If metal debris is present, it must be thoroughly cleaned, otherwise the new turbo will be damaged.
- Pre-lubricate oil: Pour clean engine oil into the new turbo oil inlet until oil flows from the outlet, ensuring bearing pre-lubrication.
- Install new turbo: Install the new turbocharger, replace all gaskets and seals, and tighten exhaust manifold bolts and oil line fittings to the specified torque.
- Connect lines: Connect oil inlet/outlet lines, coolant lines, and intercooler piping, ensuring clamps are secure.
- Pre-start check: Confirm normal oil level and manually rotate the turbo rotor to confirm no interference. After starting, idle for 1–2 minutes and check oil lines and exhaust fittings for leakage.
- Every 10,000 km or 12 months: Check oil level and quality; inspect turbocharger exterior for oil or coolant seepage.
- Every 30,000–50,000 km: Check intake piping sealing and intercooler cleanliness; inspect turbo axial/radial play.
- When power loss, sluggish acceleration, blue/white exhaust smoke, or turbo noise is detected: Inspect turbocharger condition and lubrication system promptly.
