JCB Rear Arm Kingpost (New Type) - OEM
Original kingpost (swing post) designed for mounting the rear excavator arm. This is a critical OEM JCB load-bearing component that serves as the pivot point for the entire backhoe attachment. The new casting type features improved geometry, resulting in greater rigidity and durability of the entire swing system.
Technical Features and Advantages:
- Modern Construction: Optimized stress distribution within the kingpost body minimizes the risk of fatigue cracking during heavy demolition work and deep excavations.
- Precision Pin Housings: Main pin bores are machined with the highest accuracy, ensuring perfect arm alignment and eliminating attachment "play" during operation.
- Integrated Lubrication Channels: An optimized grease delivery system to the swing bushings ensures longer pin life and reduces metal-on-metal friction.
Compatibility with JCB Backhoe Loaders:
| Machine Type | Models / Variants |
|---|
| Backhoe Loaders |
210, 212, 214, 215, 217, 2CX, 3, 3C, 3CS, 3CX, 4CX |
Technical Advice: Replacing the kingpost is the perfect time to install a complete set of new pins and bushings. Even minimal play on old pins can lead to rapid wear of the bores in the new casting. After installation, remember to check the operation of the swing cylinders and their end-of-stroke cushioning to avoid violent impacts (shocks) that stress the kingpost structure.
