Key Checking Points Before Order

Turbochargers should not be confirmed only by excavator model. The same EX120 or EX150 series machine may have different engine versions, replacement history or turbocharger specifications, so the old turbocharger plate number and engine model should be checked before quotation.

Part Number Check: Confirm 8-94418-3200, 8-94418-3201 or 8944183200 from the old turbocharger tag, supplier record or removed sample.

Turbo Model Check: Confirm whether the old turbocharger is marked as RHB6 or RHB6A series.

Engine Check: Confirm whether the engine is Isuzu 4BD1-T, 4BD1 or a related 4BD1 engine version.

Machine Check: Confirm Hitachi EX120-1 or EX150 application if the turbo is ordered by machine model.

Sample Check: Provide photos of the old turbocharger from the compressor side, turbine side, actuator side and nameplate side.

Turbocharger Replacement Notes

Before replacing the 8-94418-3200 RHB6 turbocharger, the engine air intake system, exhaust manifold, oil feed line, oil return line and air filter condition should be checked. Turbocharger failure can be caused by oil starvation, dirty oil, air restriction, exhaust leakage or foreign object damage.

After installation, the lubrication system should be primed before engine start. The oil line should be clean, the intake pipe should be free from debris, and the engine should be checked for abnormal smoke, oil leakage, boost pressure loss or unusual turbo noise during testing.
