  • Example: KM843 (confirm via Komatsu parts catalog or dealer).

  • Always verify with your machine’s serial number (SN).

2. Replacement Specifications

• Dimensions: Varies by model; measure old idler (shaft diameter, width, bolt pattern).

• Compatibility: Ensure compatibility with D65-8 (other D65 models may differ).

• Material: Typically forged steel with hardened surfaces for durability.

3. Common Issues

• Wear Signs: Excessive track sag, misalignment, or visible damage to idler wheels/seals.

• Causes: Lack of lubrication, abrasive environments, or improper tension.

4. Replacement Tips

• Tools Needed: Hydraulic jack, track press (for tension adjustment), torque wrench.

• Steps:

  1. Release track tension.

  2. Remove track chain (if necessary).

  3. Unbolt and replace idler assembly.
