Operating Notes for Genuine Excavator Turbocharger

    The turbocharger is an important component that improves engine power and reduces exhaust emissions. It uses the inertia impulse of exhaust gas to drive the turbine, which drives the coaxial impeller to compress air from the air filter and deliver it into the cylinder.

    Since the turbocharger operates at high speed and high temperature, the following points must be noted:

1. Do not drive immediately after starting: Idle the engine for a period after starting, especially in winter, to fully lubricate bearings before the rotor runs at high speed. Do not rev the engine violently to avoid damaging the turbocharger oil seal.

2. Do not shut down immediately: After long-time high-speed operation, do not turn off the engine at once. Engine oil lubricates and cools the turbocharger bearings. Sudden shutdown causes oil pressure to drop to zero immediately, while the rotor still rotates at high speed due to inertia. Residual oil will overheat and damage bearings and shafts. Avoid revving violently then shutting down suddenly.

3. Keep clean: Block all pipe connections with clean cloth during disassembly to prevent debris from entering and damaging the rotor. Avoid impacting the impeller during maintenance; perform dynamic balance test if replacing the impeller. Remove plugs after reassembly.

4. Clean regularly: Oil lines tend to coke at high temperatures, causing insufficient lubrication and bearing damage. Clean the oil lines after a period of use.

5. Inspection: Check air pipe connections before departure and after shutdown to prevent looseness or falling off, which may cause turbocharger failure and unfiltered air entering the cylinder. Improper use and maintenance easily lead to turbocharger faults and abnormal engine operation. Please choose our genuine accessories for replacement for high cost performance and reliable use.
