This aftermarket replacement fastener is machined with visible tool marks on the surface. The hexagonal design allows for standard torque application during turbocharger reassembly. Buyers should verify the thread pitch and diameter against their specific KTR130-534AW turbocharger configuration, as these dimensions are not explicitly listed in the product data. Confirming the correct shaft nut specification helps ensure proper clamping force and prevents potential damage to the turbocharger shaft during installation.

Application & Compatibility

Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:

This shaft nut is listed for reference applications on Komatsu SAA6D170E series engines. Specific application clues include:

• KOMATSU > KOMATSU HD465-7 > KOMATSU SAA6D170E-5B
• KOMATSU > KOMATSU HD465-7R > KOMATSU SAA6D170E-5BR
• KOMATSU > KOMATSU WA600-6 > KOMATSU SAA6D170E-5A
• Komatsu HD465-7 with SAA6D170E-5B engine
• Komatsu HD465-7R with SAA6D170E-5BR engine
• Komatsu WA600-6 with SAA6D170E-5A engine

These paths serve as verification clues rather than confirmed fitment. Buyers should cross-reference the part number 6502-51-0410 and engine code against their specific turbocharger configuration. Verify the KTR130-534AW turbo model and engine variant before ordering to ensure the correct replacement application.

Technical Notes

The KTR130-534AW turbocharger assembly utilizes a hexagonal shaft nut to secure the turbine shaft. This fastener features a flanged base and internal threads, visible in the product imagery as a silver-colored machined component. During CHRA reassembly, proper torque application is essential to maintain shaft alignment and prevent vibration. Buyers should verify the specific thread pitch and diameter against their existing turbocharger configuration, as these dimensions are not explicitly listed in the product data. Confirming the correct shaft nut specification helps ensure proper clamping force and prevents potential damage to the turbocharger shaft during installation.
