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.
