DA640 Engine Turbocharger 8609809

8609809 H2C Turbocharger for DA640 Engine Application

The 8609809 H2C turbocharger is supplied for DA640 engine application repair and replacement. It is used to recover engine boost pressure, improve air intake efficiency and support stable combustion when the original turbocharger has oil leakage, weak boost, excessive shaft play, abnormal noise or damaged compressor and turbine components.

This replacement turbocharger should be matched by the old turbocharger number, turbo model, engine model and removed sample. Since turbocharger housing, flange, compressor outlet direction and oil pipe positions can differ by engine version and equipment application, the old turbocharger tag and sample photos should be checked before order confirmation.

Main Part Number and Ref Cross

The main part number is 8609809. Ref Cross numbers such as 53279706206 and 3518613 can be used for inquiry matching. Final matching should still be confirmed by checking the old turbocharger nameplate, engine model and removed sample photos before shipment.

Part Number: 8609809

Ref Cross: 53279706206 / 3518613

Turbo Model: H2C series turbocharger

Application: DA640 diesel engine application

Product Type: Engine Turbocharger

Application Matching Notes

For DA640 engine applications, this turbocharger should be confirmed by the engine plate, old turbocharger number and physical sample. Equipment model alone is not enough for final matching because turbocharger arrangement can vary by machine version, engine configuration and previous replacement history.

Engine Check: Confirm DA640 engine application or the actual engine model from the engine plate.

Turbo Tag Check: Confirm 8609809, 53279706206, 3518613 or H2C on the old turbocharger nameplate.

Sample Check: Compare compressor housing, turbine housing, mounting flange and oil inlet / return position.

Photo Check: Provide clear photos of the old turbocharger nameplate, compressor side, turbine side and mounting side.

Final Matching Rule: Use old turbo nameplate, engine model and removed sample photos before quotation.

Common Replacement Conditions

A worn 8609809 H2C turbocharger can cause weak boost, black smoke, slow engine response, oil leakage, abnormal compressor noise or excessive shaft play. Before replacing the turbocharger, the air intake, exhaust and lubrication systems should be checked to reduce the risk of repeat turbo failure.

Weak Boost or Black Smoke: Check the air filter, intake pipe, intercooler pipe and compressor wheel for blockage, leakage or foreign object damage.

Oil Leakage: Check the oil feed line, oil return line and crankcase ventilation. A blocked oil return line can force oil through the turbocharger seal area.

Abnormal Turbo Noise: Check shaft clearance, bearing wear, wheel contact marks and signs of contaminated oil before installing the replacement turbocharger.

Installation and Failure Check Notes

Before replacing the 8609809 turbocharger, check the air intake pipe, exhaust manifold, air filter, intercooler pipe, oil feed line and oil return line. A failed turbocharger can be caused by dirty oil, low oil pressure, blocked oil return, air restriction, exhaust leakage or foreign object damage.

During installation, clean the oil line and pre-lubricate the turbocharger before engine start. After installation, inspect for oil leakage, blue smoke, black smoke, slow boost response, abnormal compressor noise and exhaust leakage during machine testing.
