HIDROMEK-HMK370 Final Drive Sprocket Group/CQC track supply OEM quality crawler undercarriage parts

Hidromek HMK370 Final Drive Sprocket Group – Technical Summary

1. Function & Importance

• The final drive sprocket (also called the track sprocket) is a critical undercarriage component that:
  • Transmits power from the final drive motor to the track chain.
  • Engages with track links to propel the excavator.
  • Must withstand high torque and abrasive wear.

2. Compatibility

• Primary Model: Designed for Hidromek HMK370 excavators.
• Possible Cross-Model Compatibility:
  • May interchange with other Hidromek HMK series machines (e.g., HMK370, HMK370-9) if sprocket tooth count and bolt patterns match.
  • Verify with OEM specs before purchasing.

3. Key Specifications

• Material: High-carbon alloy steel (heat-treated for durability).
• Tooth Count: Typically 11–13 teeth (confirm for HMK370).
• Mounting Type: Bolted or integrated with the final drive assembly.
• Sealing: Integrated with the final drive’s oil bath system (prevents debris ingress).

4. Signs of Wear or Failure

• Worn/rounded sprocket teeth (causes track slippage).
• Cracks or broken teeth.
• Unusual grinding noises from the final drive.
• Track misalignment or excessive play.

5. OEM vs. Aftermarket Options

Recommendation:

• For long-term reliability, choose OEM.
• For cost savings, select ISO-certified aftermarket brands (CQC, Berco, ITR, Prowell).

6. Where to Buy?

• Hidromek Dealers: Genuine parts (provide your machine’s serial number).
• Undercarriage Specialists: E.g., Vema Track, Trackparts Europe.
• Online Marketplaces: TradeMachines, MachineryTrader (verify seller ratings).

7. Installation Tips

1. Inspect the final drive for damage before replacing the sprocket.
2. Replace track chains/pads if worn (mismatched wear causes premature failure).
3. Use torque specs for bolt tightening (prevents loosening).
4. Check oil seals to prevent leaks.
