6207-81-8331 Turbocharger for Komatsu PC200-6 PC210-6 S6D95L

6207-81-8331 Turbocharger for Komatsu S6D95L Engine

The 6207-81-8331 turbocharger is used for Komatsu S6D95L and 6D95L diesel engine air intake and boost pressure repair. It is commonly checked for Komatsu PC200-6, PC200LC-6, PC210-6 and PC210LC-6 excavator applications, and it may also appear in PC150 and PC220-6 market references depending on engine configuration.

This replacement turbocharger should be matched by the old turbocharger number, engine model, machine model and removed sample. Since turbocharger housing, exhaust flange, oil line position and intake connection 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 6207-81-8331. Ref Cross numbers such as 6207-81-8330, 314334, 314317, 313075 and 312322 can be used for inquiry matching. Final confirmation should still be based on the old turbocharger nameplate, engine model and physical housing comparison before shipment.

Main Application: Komatsu PC200-6 / PC200LC-6 / PC210-6 / PC210LC-6 excavator

Related Application: PC150, PC220-6 and related S6D95L engine applications, verify by old turbo tag and sample photos

Application Matching Notes

For Komatsu PC200-6 and PC210-6 applications, this turbocharger should be confirmed by engine plate, old turbocharger number and physical sample comparison. Machine model alone is not enough for final matching because the same machine family can use different turbocharger arrangements depending on engine version, production year and replacement history.

Engine Check: Confirm Komatsu S6D95L or 6D95L engine model from the engine plate.

Machine Check: Confirm PC200-6, PC200LC-6, PC210-6, PC210LC-6 or the actual equipment model.

Turbo Tag Check: Check for 6207-81-8331, 6207-81-8330, 314334, 314317 or related number marks.

Compressor Side Check: Compare inlet size, outlet angle, housing shape and clamp connection.

Turbine Side Check: Check exhaust flange, bolt pattern, outlet direction and housing profile.

Lubrication Port Check: Confirm oil inlet, oil outlet, pipe position and return line direction.

Common Replacement Conditions

On Komatsu PC200-6 and PC210-6 excavators, turbocharger problems may appear as black smoke, weak digging power, slow engine response, abnormal turbo noise, oil leakage, high exhaust temperature or excessive shaft play. These symptoms should be checked together with the air filter condition, exhaust restriction, fuel injection condition and engine oil quality.

Black Smoke Under Load: Check boost pressure, air filter restriction, intake leakage, compressor wheel condition and fuel injection status.

Weak Engine Power: Inspect the compressor wheel, exhaust leak, boost hose, intercooler condition and turbine housing damage.

Oil in Intake Pipe: Check the turbo seal area, bearing wear, oil return restriction and crankcase pressure.

Whining or Scraping Noise: Inspect shaft play, compressor blade contact, turbine wheel damage and foreign object impact.

Repeated Turbo Failure: Check the oil feed line, oil return pipe, air filtration, exhaust restriction and the root cause of the previous failure.

Oil Line and Air Intake Inspection

Turbocharger replacement should include an oil supply and oil return check. If the oil feed pipe is restricted or the oil return line is blocked, the new turbocharger may develop bearing damage, oil leakage or smoke shortly after installation.

Inspect engine oil quality, oil pressure, oil filter condition and oil return path before fitting the replacement turbocharger. Old carbon deposits in the oil line can damage the turbo bearing system.

For machines working in dusty or high-load conditions, also inspect the intake pipe and air filter sealing. Dust ingestion can damage the compressor wheel and reduce turbocharger efficiency.

Installation Notes for 6207-81-8331 Turbocharger

Before installation, clean the intake pipe, exhaust connection and oil line area. Remove old gasket material, carbon deposits and loose debris that may enter the turbocharger.

Prime the turbocharger with clean engine oil before starting the engine. Dry startup can damage the bearing system within a short time.

Replace or inspect the air filter, engine oil, oil filter and related sealing parts during turbocharger replacement. A restricted air filter or contaminated oil can shorten turbocharger service life.

After installation, let the engine idle briefly and check for oil leakage, exhaust leakage, abnormal noise, smoke, boost response and oil pressure before putting the machine back into heavy work.
