Repair Shop Checkpoints

A failed 2674A209 turbocharger can show different symptoms on the machine. The following checkpoints help repair shops identify whether the turbocharger should be replaced and whether the engine system needs additional cleaning before installation.

Boost Loss: Check intake leakage, compressor wheel damage, actuator movement, exhaust restriction and boost pipe condition.

Black Smoke: Check air filter restriction, intake pipe leakage, low boost pressure and fuel injection condition.

Oil Leakage: Check the oil feed line, oil return line, crankcase ventilation and turbo bearing clearance before installing a replacement turbocharger.

Abnormal Noise: Check shaft play, compressor blade contact, turbine wheel damage and foreign object impact marks.

Repeat Failure Risk: Check dirty oil, blocked oil return, damaged air filter sealing and remaining debris in the intake pipe before starting the engine with the new turbocharger.

Installation Notes

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. Replace damaged gaskets and inspect the air filter, oil filter and engine oil condition during turbocharger replacement.

Prime the turbocharger with clean engine oil before first startup. After installation, let the engine idle briefly and check oil leakage, exhaust leakage, abnormal turbo sound, smoke, boost response and oil pressure before returning the machine to working load.
