Installation And Inspection Items

Inspection of turbocharger

1.Inspect turbocharger model whether it matches the engine.

2.Rotate the rotor by hand, if the hysteresis of impeller occurs or having the feeling of rubbing the housing, please install after finding out the reason.

Inspection the air inlet and outlet pipeline of the engine

1.Inspect whether air filter is clean. If the air filter is not clean, it may cause leakage of oil of the turbocharger.

2.Inspect whether there are sundries in the air inlet pipeline of the air compressor and engine outlet pipeline in front of the turbine wheel, preventing the damage of the impeller.

Inspection the oil inlet pipeline of the turbocharger

1. Inspect whether the oil filter needs to be replaced. After replacing the filter, we should fill clean oil in the filter fully. Inspect whether the oil inlet of the turbocharger is clean, the oil inlet pipe cannot be twisted or blocked.

2.If the oil inlet of the turbocharger uses the sealed sheet gasket, inspect whether the sheet gasket has been damaged or corrosive. If so, then replace the sheet gasket.

3.Inspect whether the oil is clean. If not, replace it immediately. The replacement should be carried out under the hot state, in order to avoid dirty stuff sticks on the oil sump. The oil should be the trademark which the engine manufactory assigns. The rank of machine oil must not be lower than CD15W/40.

The pre-lubrication of the turbocharger

1. Only had inspected all above, and eliminated the undesirable tendency, then it is available to install the turbocharger on the engine.

2. After the installation of the turbocharger on the engine, please do not connect it with the oil inlet pipe at this stage. First add clean oil into the turbocharger through the oil inlet, and rotate the rotor by band. Connect the oil inlet pipe until the turbocharger bearing system is filled with oil.

Inspection the return oil pipeline of turbocharger

1.The return oil pipe cannot be twisted, transited or blocked, the cross-sectional area of the return oil pipe should be larger than or equal to the area of the return oil inlet of the turbocharger.

2. Inspect whether the sheet gasket of the return oil inlet has been distorted, damaged or invalidated. The sheet gasket cannot block the return oil inlet.

3.Inspect oil level in engine crankcase. If it is lower than the scale, add oil to the stipulation oil level.
