JCB Track Tensioner / Cylinder O-ring 40x3mm - AZERI PARTS 2302/0151
The AZERI PARTS sealing O-ring (40x3 mm) is a multi-purpose sealing component used in JCB machinery. In mini excavators, it is part of the track tensioning system, preventing grease leaks from the tensioner cylinder. In telescopic handlers, it serves as a technical seal in hydraulic cylinder sections, ensuring full efficiency under high operating pressure.
Technical Specification:
- Dimensions: 40 mm (internal diameter) x 3 mm (cross-section thickness).
- Application 1: Track tensioner cylinder (Mini excavators).
- Application 2: Hydraulic cylinder seal (Telescopic handlers).
- Material: High-resistance elastomer (resistant to oils, grease, and mechanical pressure).

Workshop Tip: When servicing the track tensioner, replacing the O-ring is critical for maintaining constant undercarriage tension. Before installing the new seal, thoroughly clean the tensioner piston of any old grease and sand residue, which could damage the new rubber. To facilitate installation and prevent the edge from rolling, it is recommended to lightly moisten the O-ring with technical oil or grease.
