Turbocharger Repair Services

TURBOCHARGER REPAIR PROCEDURES

Our repair services focus on restoring damaged turbocharger components to OEM tolerances. First, we conduct a root cause analysis to identify the source of the damage, then apply appropriate welding, filleting, machining, or resurfacing techniques. After the repair, the parts undergo heat treatment, machining, and balancing processes, and are verified with NDT tests such as measurement, penetrant, or magnetic particle testing. All processes are documented with quality records and secured through performance testing..

Compressor Wheel Blade Repair

Compressor wheel blades are repaired for erosion, nicks, deformation, and foreign object damage, preserving component integrity and aerodynamic profile. Precision grinding, micro-welding, and balancing processes bring blade angles and profile tolerances back to OEM specifications. This reduces flow losses and vibration levels, while optimizing compressor efficiency and compression ratio. At the end of the process, the part undergoes balancing and dimensional verification tests and is reported.

Turbine Rotor Blade Repair

Cracks, wear, and deformations observed in turbine rotor blades exposed to high temperatures and corrosive gas flows are eliminated through appropriate filling and heat treatment processes. The blade root and trailing lip areas are specifically inspected, and material integrity is verified using NDT methods. The aerodynamic profile and blade clearances are restored, restoring the turbine’s energy conversion efficiency and mechanical strength. In the final stage, dynamic balancing reduces vibration levels to the nominal range.

Nozzle Ring Vane Repair

The surface roughness, clearance, and angle tolerances of the guide vanes on the nozzle ring are critical to flow performance. By eliminating wear and corrosion-related deterioration, proper flow and pressure distribution are achieved. Coating/reconditioning processes are performed when necessary, and the part’s sealing and geometric conformity are measured. This results in low pressure loss and balanced turbine delivery, improving overall turbocharger efficiency.

Turbine Rotor Ring Groove Repair

Wear, increased clearance, and ovality in the ring groove pose critical risks to oil sealing and bearing health. Precision machining, filling, and grinding operations restore nominal dimensions to the groove. Surface roughness and ring fit tolerances are matched to OEM specifications, and post-assembly verification is performed through oil leakage tests and balance checks. This process significantly reduces oil consumption and bearing wear.

Turbine Rotor Shaft Repair

Wear and runout problems on the bearing, seal, and pump surfaces of the rotor shaft are eliminated through controlled coating/filling and precision grinding. After shaft accuracy and concentricity measurements are achieved, the necessary heat treatment and balancing steps are applied. Final dimensions are adjusted to OEM tolerances, optimizing bearing-oil film behavior and ensuring safe operation at high speeds. The entire process is documented with traceable quality records.

Silencer Repair and Seal Renewal

Intake silencers and seals are periodically inspected for noise control and sealing performance. Damaged seals and insulation materials are replaced, and any cracks or deformations on the casing are repaired. After cleaning and shutting down, leak-tightness, pressure, and noise levels are tested to verify system stability. This enhances both comfort and equipment safety.
