5I-7952 49179-02260 TD06H Turbocharger for Caterpillar S6K 3066T Engine

5I-7952 Turbocharger for Caterpillar S6K 3066T Engine

The 5I-7952 / 49179-02260 turbocharger is used for Caterpillar S6K and 3066T diesel engine applications. It is commonly searched as a TD06H turbocharger, CAT 320 turbo, E320 turbocharger or S6K engine turbocharger for excavator engine repair.

This page focuses on 5I-7952 and 49179-02260 as the main part numbers. Before ordering, the removed turbocharger should be checked by turbo tag number, engine model, compressor housing, turbine housing, oil inlet outlet position, exhaust flange and machine serial number.

Caterpillar S6K 3066T Turbocharger Application

The main engine references for this turbocharger are Caterpillar S6K, S6K-DT and 3066T. These engines are commonly associated with CAT 318C, 320, 320A, 320B, 320BL, 320L, 320N and E320 excavator references.

Machine model names should be treated as checking references only. Turbocharger configuration can vary by engine version, exhaust layout, housing orientation and previous repair history. Final fitment should be confirmed by the old turbo tag and physical connection points.

TD06H Reference Numbers and Catalog Checking Notes

The main part numbers for this page are 5I-7952 and 49179-02260. The no-hyphen search formats 5I7952 and 4917902260 may also be used when checking catalogs or buyer inquiries.

Public TD06H turbocharger catalogs may list several related Caterpillar, Mitsubishi and MHI reference numbers in the same broad S6K / 3066 / 3066T turbocharger family. These references can help with identification, but they should not be treated as automatic interchange numbers without checking the old turbocharger tag and physical configuration.

• Main page numbers: 5I-7952, 49179-02260, 5I7952, 4917902260.

• TD06H catalog checking references may include 49179-02220, 49179-02230, 49179-02240, 49179-02300, 49179-02330, 49179-02340, 49179-02350, 49179-02360 and 49179-02390.

• Caterpillar catalog checking references may include 5I-8018, 205-6741, 222-8219, 10R-7610 and 205-6775 when buyers are checking a related TD06H / 3066 turbocharger group.

• Mitsubishi or MHI checking references may include ME2056741 and ME518122 in some supplier catalogs.

• Turbo model references may include TD06H, TD06H-16M and TE06H series descriptions, depending on the catalog source.

Because these numbers may cover different TD06H turbocharger versions, final confirmation should be based on the old turbo tag, turbo model, compressor housing, turbine housing, oil inlet position, oil return position, exhaust flange and air outlet direction. If the old unit shows 5I-8018 or another related number instead of 5I-7952, it should be checked as a related TD06H catalog reference, not automatically treated as the same turbocharger.

How to Identify the Correct 5I-7952 Turbo

• Check whether the old turbo tag shows 5I-7952, 5I7952, 49179-02260 or 4917902260.

• Confirm the engine model, especially Caterpillar S6K, S6K-DT or 3066T references.

• Compare compressor housing direction and air outlet position.

• Check turbine housing shape, exhaust flange and mounting orientation.

• Compare oil inlet and oil return position with the removed turbocharger.

• Check whether the old unit has been repaired or replaced before, because housing orientation may not always match the machine model name.

Common Failure Symptoms

• Engine power loss under load because boost pressure is lower than normal.

• Black smoke caused by poor air supply, fuel system issues or restricted intake flow.

• Blue smoke or oil consumption caused by turbo seal wear, high crankcase pressure or oil return restriction.

• Abnormal whistle, scraping noise or vibration caused by shaft play or wheel damage.

• Oil leakage around compressor side, turbine side, oil feed line or oil return pipe.

• Repeated turbo failure caused by dirty oil, blocked air filter, exhaust restriction or incorrect installation.

Troubleshooting Before Replacement

Before replacing the 5I-7952 turbocharger, inspect the complete air intake, exhaust and lubrication system. Turbocharger damage may be caused by problems outside the turbo itself.

• Check engine oil level, oil quality and oil change history.

• Inspect the oil feed line and oil return pipe for blockage, carbon build-up or leakage.

• Check the air filter, intake hose and compressor inlet for dust entry or restriction.

• Inspect exhaust manifold, gasket surface and turbine housing connection for leakage.

• Check for foreign object damage on compressor wheel and turbine wheel.

• Confirm whether low power or smoke is caused by turbocharger failure, fuel injection issues, air restriction or engine wear.

Installation and Maintenance Notes

• Clean the oil feed line, oil return line and mounting surfaces before installation.

• Replace damaged gaskets, seals or oil line fittings during turbocharger replacement.

• Prime the turbocharger with clean engine oil before first startup.

• Do not start the engine with blocked oil supply or dry turbo bearings.

• Check air intake hose, exhaust flange and clamp connections after installation.

• Let the engine idle and check oil leakage, abnormal noise and smoke before heavy load operation.

• Maintain clean oil, clean air filtration and correct shutdown practice to reduce early turbocharger failure.
