Technical Notes

The 3519276 HC5A compressor wheel features radial fan blades with a curved, swept-back geometry and a central cylindrical hub. A keyway slot is visible on the hub, while the backplate appears smooth and flat. The unit displays a uniform grey metallic finish, consistent with cast or machined metal construction. Material grade is not specified in the visible data; verify material specifications against your engine requirements. Inspect the old unit for foreign object damage (FOD) on the shaft or housing before installing this replacement. Ensure the turbine wheel shaft diameter and material match the original component to maintain stable operation. Cross-check the 46 associated OEM reference numbers, such as 3523419 and 3523420, to confirm the correct part for your Cummins KTTA50 application.
