JCB Center Pivot Pin Washer
Center pivot pin washer by AZERI PARTS, dedicated to the articulation system of JCB wheel loaders. This is a precision shim element responsible for eliminating axial play in the machine's main pivot point. Made of high-hardness, compression-resistant steel, the washer ensures proper force distribution within the joint, which is crucial for machine handling stability and protecting pin seats from wear.
Significant product features:
- Play Reduction: Allows for precise elimination of play in the center joint, which removes knocking and frame "sway" during travel and loading operations.
- High Material Durability: Specialized heat treatment ensures the washer does not suffer premature deformation under the immense pressures occurring in heavy loaders.
- Pin Protection: Prevents direct friction between frame components by absorbing sliding loads and protecting main structural elements.

Technical Advice: Play in a loader's center pivot is one of the most dangerous operational issues—it not only destroys pins and bushings but can lead to frame cracks and damage to the drive shafts passing through the center of the machine. Check the condition of spacer shims during every inspection. If you notice a shim is heavily worn or has fallen out, replace it immediately, selecting the appropriate thickness. Remember to lubricate the joint regularly to minimize friction on the washer surface.
