Technical Notes

The KTR110G-444S turbocharger is a heavy-duty unit commonly associated with Komatsu construction equipment. As a critical fastening component, the 6505-11-0410 shaft nut secures the turbine shaft assembly. During inspection, verify the thread specification and shaft dimensions against your service manual. Ensure the existing nut is not cross-threaded or damaged before installation.

Product FAQ

Inspect the turbocharger shaft for wear or scoring and verify the KTR110G-444S model matches your application. Ensure the new 6505-11-0410 nut is the correct thread specification for the shaft.

Excessive shaft play, unusual noise from the turbocharger, or oil leaks around the shaft seal often indicate a loose or damaged shaft nut. Check the KTR110G-444S unit on Komatsu D155 or HD785-5 machines for these signs.

If the turbine or compressor wheels are damaged, or if the CHRA shows significant wear, replacing the complete KTR110G-444S turbocharger is often more reliable than just the shaft nut. Assess total repair cost versus unit replacement.

This part is a reference application for Komatsu SA6D140E and SA12V140 engines, found in models like the D155, D155A-3, and HD785-5. Always verify the specific engine code on your machine before ordering.

Compatibility Verify part number 6505-11-0410, engine code (e.g., SA6D140E), vehicle application (e.g., Komatsu D155), and turbo model KTR110G-444S before ordering. This is an aftermarket replacement application; confirm fitment with your service manual or OEM reference numbers.
