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.
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.

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

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.
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.
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!
