At Turboworks every remanufactured (reconditioned) turbocharger is subjected to a very strict QC process, ensuring our customers receive a remanufactured turbocharger that is as good as a new one.

Turbocharger Oil-pressure/leak testing
Our oil-leak testers, which use aeronautical technology to analyses oil leaks allow us to test for oil leaks from both the compressor and the turbine sides of the turbocharger. Oil leak testing forms part of the rigorous Quality Control undergone by all turbochargers we build.

Turbocharger Balancing
Some turbocharger impellers reach speeds of up to 250,000 rpm. Unbalance at high speed generates vibration that will inevitably cause catastrophic failure to the turbocharger. Turbo balancing machines are vital in the repair process of your turbocharger, ensuring it works perfectly to manufacturer’s specifications.

When a turbocharger is VSR balanced, the Centre Housing Rotating Assembly (CHRA) is fitted in the VSR balancing machine. It’s then put through high-speed balancing, with oil fed to the CHRA. This means it gets spooled up to high RPM and emulated being installed in a vehicle. During this process, we look for harmonics in that shaft and wheel, and any anomalies are rectified.

Flow-bench testing
Turboworks uses a VNT flow bench to ensure variable-nozzle turbochargers are calibrated to original parameters. This sophisticated piece of equipment allows Turboworks’ technicians to adjust turbocharger variable nozzles fitted with pneumatic as well as electronic actuators. It enables one to set the correct position of the variable nozzle vanes and consequently the correct minimum and maximum flow of the turbocharger. This allows the turbocharger to function optimally and not over/under-boost.

Final Quality Control Inspection
A final, visual inspection is done to ensure material, dimensions and surface finishes are to specification.
