3Cx Ram Pivot Pin For JCB Part Number: 811/80012
Part No.
HMP4291
The JCB 3CX Ram Pivot Pin (OEM 811/80012) is a direct replacement hardened pivot pin designed for use on JCB 3CX and 4CX backhoe loaders. It forms part of the hydraulic ram and linkage assembly, providing a secure pivot point between the hydraulic cylinder and machine structure while allowing smooth articulation during loader and backhoe operation.
Manufactured to OEM specifications, this pivot pin is engineered for high load-bearing strength, wear resistance, and durability under demanding construction and earthmoving conditions. It is designed to withstand constant articulation movement, shock loading, vibration, and heavy hydraulic forces encountered during excavation and loading operations.
FUNCTION AND OPERATION
- Provides a secure pivot point for hydraulic ram movement
- Allows controlled articulation of loader or backhoe linkage assemblies
- Maintains alignment between ram and mounting brackets
- Designed to withstand heavy hydraulic loads and impact forces
- Helps reduce wear within the linkage and pivot system

TYPICAL APPLICATIONS
Suitable for a range of JCB equipment, including:
- JCB 3CX backhoe loaders
- JCB 4CX backhoe loaders
- Loader arm and bucket linkage systems
- Hydraulic ram pivot assemblies
- Excavator and backhoe articulation points
Pivot pins of this type are commonly used throughout loader and dipper assemblies where repeated hydraulic articulation and heavy-duty movement occur during digging and loading operations. Industry repair discussions also commonly reference pivot pin wear and seizure as a maintenance item on heavily used plant equipment.
IMPORTANT INFORMATION
Always confirm the correct OEM part number, machine model, and serial number before ordering, as pivot pin dimensions, grease channel configurations, and retaining arrangements may vary depending on machine series and production range. Worn or incorrectly fitted pivot pins can result in excessive play, poor linkage alignment, accelerated bush wear, or hydraulic ram instability during operation.
