Check for Free Rotation -- On Vehicle
WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The turbocharger must be pre-oiled before carrying out this check.
NOTE:
Turbine and compressor wheels must spin freely when turned by hand. No housing contact is permitted.
Inspect the turbocharger compressor and turbine fins for damage. If the compressor or turbine wheel fins are damaged, install a new turbocharger.
Press and rotate the turbocharger shaft. If either the compressor wheel or the turbine wheel contacts the housing, the bearings are bad and a new turbocharger must be installed.
