It is a tight squeeze through the oil return hole but make sure the contact point is directly centered on the shaft.Register User Name: Password. Attach the dial indicator with an extension indicator point long enough to make contact with the shaft. The most accurate reading without completely disassembling the turbo is through the oil return hole. To check for radial spec first detach the oil return line from the turbo. Much like end play clearance, radial clearance can also be measured with a dial indicator. The fix is to simply disassemble and clean the turbine wheel or replace worn parts. Consequently if the end play is below spec it could indicate carbon build up on the inside of the turbine wheel. The only way to correct a surplus of end play is to either rebuild or replace the turbocharger.
If the end play is out of spec you will know. For upgraded T12 Turbos the spec end play should be. Slowly move the indicator from end to end making note of the reading around the radius until the entire clearance is accounted for. To measure the clearance attach a dial indicator with the indicator point on the end of the shaft. Sure you can feel if something is amiss, however clearance is best measured with a dial indicator. If you feel the impeller is rubbing against the inside of the compressor cover or the turbine wheel is grinding against the inside of the turbine housing, pull a part the entire turbo as the bearings are shot or simply replace the turbo. The rotating assembly should move without any restrictions which includes any rubbing or binding up in one particular spot. Once you have inspected the condition of those parts rotate the compressor and turbine wheel assembly by hand and get a feel for excess end play and radial clearance. To inspect the bearings you can remove the piping from the turbocharger and inspecting the compressor impellerturbine wheel and compressor cover. The turbocharger should be inspected every - hours for abnormal vibration or noise. There really aren't too many glaring issues with the turbo or aftercooler intercooler however this article will dig deeper into some of the most common problems regarding the air flow.
