Pin Retaining Clip 40mm suitable for JCB 3CX 4CX - 821/00309

Technical Specification and Compatibility

Pin retaining clip (linch pin/locking pin) with part number 821/00309 from the GX-AFTER offer. This is a locating element designed to lock pins with a working diameter of 40 mm. It is used in the working systems (bucket, arm, kingpost) of JCB 3CX and 4CX backhoe loaders. It prevents the pin from moving axially and falling out of the bushing.

Part Number: 821/00309
Component Type: Pin Retaining Clip / Linch Pin
Dedicated Pin Diameter: 40 mm
Material: Spring Steel
Application: Excavator Attachment Locking
Manufacturer: GX-AFTER

GX-AFTER mounting accessories are made of steel with a high modulus of elasticity. As a result, the retainer holds the pin securely, does not permanently deform during installation, and is resistant to vibrations generated during machine operation.

Features of GX-AFTER 821/00309 Retainer

Secure Lock: The shape of the clip is designed to embrace the pin or lock into its hole, preventing spontaneous withdrawal under the influence of vibrations.
Material Durability: The use of galvanized or blackened spring steel ensures resistance to corrosion and fatigue cracking.
Quick Assembly: The element allows for quick replacement of attachments (e.g., bucket) without the need to use complicated tools to secure the pins.
Fit: Perfectly fits original JCB pins with a diameter of 40 mm, ensuring appropriate working clearance.

Application in JCB machinery

Machine Type Models
Backhoe Loaders 3CX, 4CX (bucket pins, arm, kingpost, stabilizers - where 40mm diameter occurs)

Universal element for 40mm diameter in JCB machines. Make sure your pin has exactly this diameter before purchasing.

Related Parts and Hardware

The retainer works directly with 40mm pins. When replacing the retainer, we recommend checking the wear of the pin and bushings in the given kinematic node.

⚠️ Safety Warning

Loss of pin retaining clip during operation risks the pin sliding out and uncontrolled detachment of the bucket or dropping of the arm. This can lead to a serious accident. Regularly check the presence and condition of all cotter pins.

Part Role in the Machine and Failure Diagnostics

Retainer 821/00309 acts as an axial lock for pins.

  • › Pin sliding out (missing retainer).
  • › Loose cotter pin (material fatigue, bent).
  • › Corrosion of the element (risk of breakage).
  • › Difficulty in assembly (plastic deformation).

🔧 Expert Guide: Key Installation Tips

  1. One-time use: Although spring clips are theoretically reusable, we recommend replacing them with new ones every time the pin is removed. Fatigued material can break at the least expected moment.
  2. Assembly: Ensure the retainer is fully seated on the pin or has passed through the hole. It must resist when trying to remove.
  3. Cleanliness: Before installing the retainer, clean the groove or hole in the pin from mud and old grease to ensure proper seating.

Technical FAQ and Trivia

What pin diameter does it fit?

The retainer is designed for pins with a nominal diameter of 40 mm. In JCB machines, this is a very common dimension for bucket pins and the kinematic system.

Is this a Circlip?

The term "Circlip" may suggest a snap ring (Seger ring), however, number 821/00309 in JCB often refers to a specific "Linch Pin" (with a snap ring) or spring clip. It is used for quick securing of pins without using pliers.

Trivia about JCB machines

Did you know that the famous "JCB Dancing Diggers" shows rely on the incredible power of hydraulics and the precision of pin connections? These machines perform acrobatics, lifting themselves on buckets and arms. Without solid pin retainers (like 821/00309), such stunts would be impossible and extremely dangerous!
