This sound can be worrying, as it may indicate a potential problem with the driveline components, such as the differential, drive motors, or other related parts. Identifying the cause of this noise early on is crucial to prevent further damage and ensure the machine continues to run smoothly.
Common Causes of Ratchet Sound:

  1. Drive Motor Issues:
    One of the most common sources of a ratchet sound in a skid steer is an issue with the drive motors. If the drive motor is worn or malfunctioning, it can cause intermittent engagement or slipping, resulting in a ratchet-like noise. Over time, the motor may need to be replaced if this issue persists.
  2. Drive Chain or Gearbox Problems:
    The driveline includes chains or gearboxes that transfer power from the engine to the wheels. If these components become worn or damaged, they can produce a ratcheting noise. Check for any signs of wear or damage in the chain or gearbox, as these parts can fail under heavy load or lack of proper maintenance.
  3. Differential or Axle Issues:
    The differential is responsible for distributing power to the wheels. If there's a problem with the differential or axle, such as low fluid or worn gears, it can create a ratchet sound during operation. Ensure that the differential and axles are properly lubricated and in good condition.
  4. Loose or Worn Components:
    A loose part, such as a fastener or bearing, in the driveline can create a rattling or ratcheting sound. Inspect the driveline components carefully for any loose connections or worn-out parts that might be causing the noise.
Steps to Troubleshoot the Ratchet Sound:
  1. Inspect Drive Motors:
    Begin by inspecting the drive motors for any visible signs of damage or wear. If the motor is making an unusual noise when engaged, it may be necessary to replace it or service the motor.
  2. Check the Chain or Gearbox:
    Inspect the drive chain or gearbox for any signs of damage, wear, or misalignment. Tighten any loose components and replace any parts that appear to be worn out. Also, check the gear fluid levels and replace any that have become low.
  3. Examine the Differential and Axles:
    Check the differential for any oil leaks, and make sure the axles are properly lubricated. Inspect the gears for wear or broken teeth. If any issues are found, repair or replace the faulty parts.
  4. Tighten or Replace Loose Components:
    Go over all driveline components and ensure everything is tightly secured. If any fasteners or bearings are loose or damaged, tighten or replace them to prevent further damage.
Conclusion:
A ratchet sound coming from the driveline of an LS170 skid steer can be caused by various issues, including problems with the drive motor, gearbox, differential, or loose components. By performing a thorough inspection and addressing any worn or damaged parts, you can prevent the issue from worsening and ensure your skid steer runs efficiently. If you're unsure about performing these checks yourself, it's best to consult a professional mechanic who can diagnose and repair the problem accurately.
