D65-8

The Komatsu D65-8 idler ass'y (idler assembly) is a critical undercarriage component for the Komatsu D65-8 bulldozer, guiding and tensioning the track chain. Here’s key information you may need:


1. Part Identification

  • Function: The idler maintains track tension and alignment, absorbing shocks during operation.

  • Komatsu Part Number:

    • Exact part numbers vary based on configuration (e.g., standard/offset, with/without recoil spring).

    • 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.

        4. Re-tension track to Komatsu specs (refer to service manual).


      5. Where to Buy.

      CQC-track&DPQ-parts

      • Cross-Reference: Provide your old idler’s specs to suppliers for matching.


      6. Maintenance

      • Lubrication: Regularly grease idler bearings (use Komatsu-recommended grease).

      • Inspection: Check for leaks, cracks, or uneven wear during undercarriage checks.


      Note

      For accurate part numbers and procedures, always consult:

      • Komatsu D65-8 Service Manual (Section: Undercarriage).

      • Online Parts Catalogs (e.g., Komatsu Parts).

      If you need help locating a specific part number or troubleshooting, share your machine’s serial number or a photo of the old idler.
