The list above is for reference. It is crucial to verify the dimensions (40 x 175 mm) in your machine.

Related Parts and Hardware

This pin operates within the kingpost (sideshift frame) bores. When replacing, we recommend checking the bushings in the lock bores and the condition of the retaining cable.

⚠️ Safety Warning

Never attempt to slew the excavator arm while the 125/81200 lock pin is engaged. This can lead to shearing the pin, destroying the kingpost housing, or damaging the slew rams. Before operating the backhoe, always ensure the pin is removed and securely stowed.

Part Role in the Machine and Failure Diagnostics

The 125/81200 pin is a manual lock for the backhoe slew mechanism. It is inserted through special holes in the sideshift frame (kingpost) and slew carriage to lock the arm in the center position. This is essential for road transport and for operating certain attachments (like hydraulic breakers) to prevent unwanted arm swing.

  • › Pin is bent or permanently warped (from an attempt to slew while locked).
  • › Broken or missing retaining cable, leading to loss of the pin.
  • › Excessive wear (narrowing) of the 40 mm diameter, causing play even when locked.
  • › Heavy corrosion or damage to the flange, making the pin difficult to use.

🔧 Expert Guide: Key Installation Tips

  1. Verify Dimensions: Ensure the pin diameter is 40 mm and the length is 175 mm.
  2. Clean the Bore: Before inserting the pin, make sure the bores in the kingpost are clean and free of dirt, ice, or rocks.
  3. Check Alignment: The pin should slide in without excessive force. If the arm is not perfectly centered, move the slew gently until the holes align.
  4. Install Cable: Secure the retaining cable to a safe point so the pin does not fall into moving parts when removed.
  5. Lubrication: Regularly apply a light coat of grease to the pin to prevent corrosion and seizing in the bore.

Frequently Asked Questions (FAQ)

What is this pin used for?

This is a safety pin used to mechanically lock the backhoe arm (kingpost) in the center position, which is required for road transport or when using a hydraulic breaker.

Why does it come with a cable?

The retaining cable (lanyard) is used to attach the pin to the machine's frame. This prevents it from being lost when it is removed from the bore during normal digging operations.

Does this pin fit newer machines with a slew ring?

No. This pin is for machines with the "old type" slew system (using a rack and pinion). Newer machines with a slew ring (turntable) have a completely different, often automatic, slew lock system.
