Bearing Axial Clearance Check
- Attach a dial indicator with tip of indicator against end of shaft. Manually move shaft in one direction as far as possible and zero dial indicator.
- Move shaft in extreme opposite direction (without rotating shaft) and observe dial indicator.
- Rotate shaft 90° and check bearing clearance again. If bearing axial clearance is greater than .0012-.0031" (.03-.08 mm), replace turbocharger assembly.
