Check the turbocharger. If you find any bent fins or a bent shaft, please return it at once. Don’t load any force on its decompressor when carrying the turbocharger.
Before installing the turbocharger on the engine, you must lubricate it. Input the clean oil at the entrance of the oil drain and turn the “shaft and wheel” by hand.
Good engine oil is important for the turbocharger. We recommend Shell Rotella 10W-40.
Install the turbocharger on the engine, make sure that it is fastened, and sealed at the connection. Otherwise it will howl and leak oil.
After you start the engine, keep it idling for 3-5 minutes. This will ensure the turbocharger is lubricated completely. You should also idle the engine for 3-5 minutes before you shut it off as well. This will avoid coking the oil and burning the bearing. If you often operate it incorrectly, its life will be reduced.
Don’t keep idling over 10-15 minutes. Otherwise, it would cause leaking oil at the end of the “compressor wheel”.
Keep the oil pressure in the range of manufacturer’s parameter.
Inspect all connections with engine. Make sure there is no looseness, no air leak, and no oil leak.
Ensure the turbocharger oil drain line is not restricted.
Clean the air cleaner frequently. Replace often.
If the engine has not been used for period of time (not over 7 days), you should take down the intake oil duct and lubricate turbocharger before starting the engine. Input the clean oil at the entrance of the oil drain and turn the “shaft and wheel” by hand.
Change the oil and oil filter every 200 hours, sooner if on a screening plant, rock crusher, or other debris-filled applications.
Check the radial clearance and the thrust clearance by a dial gauge. If the radial clearance is less than 0.1mm or the thrust clearance more than 0.15mm, you must ask for the professional.
