Accomplishing the repairs

 

After finishing the diagnostics we start the repairs.

 

We repair only turbochargers which can be repaired.

 

Changing the repair kits – this procedure will be accomplished if there is a housing unit in good working order. In this case the worn bearings and sealing elements are replaced. All turbocharger parts are cleaned by specialized equipment.

 

Any tiny shaft’s defects are removed according to the manufacturer’s requirements. All bearings and sealing parts are replaced with new ones from the repair kit, recommended by the manufacturer.  Then we do dynamic balancing of the assembled rotor part and the next step is assembling the central unit. The balancing is done by rotating with the help of oscillation - balance machine to 250 000 rpm depending on the type. After the final fitting we do adjustment of the bypass valve.

 

We do overhaul of the turbocharger when the bearing and sealing elements are worn-out. In this case parts of the basic components have to be saved. All parts of the turbocharger are cleaned with specialized equipment. The damaged parts are replaced with new ones as follows:

 

     - A turbine housing;

     - A compressor wheel;

     - A bearing body;

     - A turbine with a shaft and other parts which can be replaced.

 

All bearing and sealing parts are replaced with a new repairs kit corresponding to the repaired unit (aggregate). Then we do dynamic balancing of the assembled rotor part and the next step is assembling the central unit (aggregate).

 

 The balancing is done by rotating with the help of oscillation- balance machine to 250 000 rpm depending on the type. After the final fitting we do adjustment of the bypass valve. 

 

The turbocharger can be exchanged if it has a serious damage, damaged turbine housing and modified geometry.

 

We can exchange it with a recycled unit made by us or with a purchase of a brand new turbocharger.

 

The cost of all these possibilities will be thoroughly discussed with You in order to be taken the best possible decision.
