Checking Turbocharger Turbine Radial Play

Radial play is checked on the turbine end only.


Be sure not to rotate the turbine wheel at all during these measurements.

1. Press turbine wheel toward side of housing, check gap with a feeler gauge and note.

2. Press turbine wheel toward opposite side of housing, check gap and note.

Difference of both measurements is the radial play. Measure play at least at two different locations.
