Product FAQ

Inspect the turbine wheel shaft for scoring, corrosion, or excessive wear. Verify the shaft diameter and material grade match the original specification for the Cummins QSK19 engine to ensure proper bearing fitment.

Check the oil feed and return ports on the bearing housing for blockages, debris, or damage. Ensure clear oil flow paths to prevent lubrication issues in the Komatsu WA600 or Hitachi ZW550 application.

Look for metal shavings, debris, or scoring on the old rotor and housing. If FOD is present, clean the oil and air systems thoroughly before installing the new 4027890 RA Rotor Assy to prevent immediate failure.
