NOTE: Use a 0.050 mm [0.002 in] blade type feeler gauge to measure the clearance between the compressor wheel and the housing.

Insert the feeler gauge between the compressor wheel and the housing.

Push the compressor wheel toward the compressor housing and the feeler gauge.

Gently remove the feeler gauge.

Repeat this procedure three times approximately 120 degrees apart.

NOTE: Some dragging of the feeler gauge can be felt as it passes along the compressor wheel blade, but force will not be required to remove the gauge.

Replace the turbocharger if any signs of pinching or binding occur when the feeler gauge is being removed.
