49178-00500 Turbocharger for Kato HD300GS HD400V2

49178-00500 TD05-10A Turbocharger for Mitsubishi 4D31T Engine

The 49178-00500 TD05-10A turbocharger is supplied for Mitsubishi 4D31 and 4D31T diesel engine applications. It is commonly checked for Kato HD300GS, HD400V2, HD450SE, Sumitomo SH120, CAT E110 and related construction machinery engine repair. This turbocharger is used to restore boost pressure, improve air intake volume and support stable engine output when the old turbocharger has weak boost, oil leakage, abnormal noise, damaged wheel blades or excessive shaft play.

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

Main Part Number and Ref Cross

The main part number is 49178-00500. The no-hyphen format 4917800500 may appear in buyer searches or old purchase records. ME080442 can be used as a Ref Cross reference for this TD05-10A / 4D31T turbocharger direction. Final matching should still be based on the old turbocharger nameplate, engine model and physical housing comparison before shipment.

Part Number: 49178-00500

Ref Cross: 4917800500 / ME080442

Turbo Model: TD05-10A / TD05 series turbocharger

Engine Model: Mitsubishi 4D31 / 4D31T diesel engine

Main Application: Kato HD300GS / HD400V2 / HD450SE

Related Application: Sumitomo SH120, CAT E110 and related 4D31T engine applications, verify by old turbo tag and sample photos

Application Matching Notes

For Mitsubishi 4D31 and 4D31T engine applications, the safest confirmation method is to check the old turbocharger number together with the engine plate and removed sample. Machine model alone is not enough for final matching because the same equipment family can use different turbocharger arrangements depending on production year, engine version and previous replacement history.

Machine Check: Confirm Kato HD300GS, HD400V2, HD450SE, Sumitomo SH120, CAT E110 or the actual equipment model from the buyer.

Engine Check: Confirm Mitsubishi 4D31 or 4D31T from the engine plate or service record.

Turbo Tag Check: Check for 49178-00500, 4917800500, ME080442 or TD05-10A on the old turbocharger tag.

Housing Check: Compare compressor housing, turbine housing, outlet direction, flange type and mounting layout.

Oil Line Check: Confirm oil inlet, oil outlet, pipe position and return line direction.

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

Common Replacement Conditions

A worn 49178-00500 turbocharger can cause low boost pressure, black smoke, weak acceleration, oil leakage, abnormal turbo noise, damaged compressor wheel or excessive shaft clearance. Before replacing the turbocharger, the air intake, exhaust and lubrication systems should be checked to reduce the risk of repeat turbo failure.

Low Boost or Black Smoke: Check the air filter, intake pipe, compressor wheel condition and boost leakage.

Weak Engine Power: Inspect the compressor wheel, turbine wheel, exhaust leak, boost hose and fuel injection condition.

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

Abnormal Turbo Noise: Check shaft play, bearing wear, wheel contact marks and signs of contaminated oil or foreign object damage.

Inspection Before Installation

Before replacing the 49178-00500 turbocharger, inspect the air filter, air intake pipe, exhaust manifold, oil feed line and oil return line. Turbocharger damage is often caused by dirty oil, blocked oil return, air restriction, exhaust leakage or foreign object damage from the intake side.

During installation, add clean engine oil into the turbocharger oil inlet and rotate the compressor wheel by hand before the first engine start. After installation, check for oil leakage, abnormal turbo noise, black smoke, blue smoke, weak boost and unstable engine response during low-speed and working-speed testing.
