Turbocharger maintenance
To extend turbocharger life and efficiency, some basically important are given below:
-
Inspect for possible oil leaks in the inlet and outlet ducts, as well as inside the turbo. A
lack of lubrication or the appearance of oily residue could lead to shaft seizure and
premature seal wear.
-
Maintain the correct condition of the air filter to prevent particles from entering the
turbocharger and damaging the turbine blades.
In the event of oil leaks, vibrations or abnormal noise, it is advisable to stop the engine
immediately. Preventive maintenance can avoid costly and unexpected repairs
.
The turbocharger is an element that works at very high temperatures. Any inspection or repair work
carried out on it must be done with the engine stopped and cold.
Turbocharger cleaning
1.
Loosen the ventilation pipe from the air intake and remove the air filter together with the air
intake.
2.
Loosen the screws on the compressor housing and remove it carefully.
3.
Immerse complete assy in petrol (gasoline) untill all dirt is disolved.
4.
Clean the housing and compressor Wheel from scoot, by using a plastic brush or scraper.
5.
Wipe and dry in air making sure that the oil ducts are perfectly clean (it is better not to use
steam wich might damage the bearings and the shaft).
6.
Make sure that the intake air filter is perfectly clan.
After the turbocharger disassembly, before the crank, be sure to prime the engine with oil to prevent
turbo damage from dry running.
Maintenance task. Exhaust gas, noise, and vibrations inspection
Inspect the exhaust system components for cranks, leaks and corrosion.
Exhaust system inspection points
1.
Check the hoses for softness, cranks or dents. Replace the hoses as needed.
2.
Check for corroded or broken metal parts and replace them as needed.
3.
Check for loose, corroded or missing clamps. Tighten or replace the hose clamps
and/or hangers as needed.
4.
Check that the exhaust outlet is unobstructed.
5.
Visually inspect the exhaust system for exhaust leaks. Check for carbon or soot
residue on exhaust components. Carbon and soot residue indicate an exhaust
leak. Seal leaks as needed.
