Bucket Link Pin 30x157mm (fits JCB) - AM 811/50175
High-quality, hardened bucket link pin with precise dimensions of 30 x 157 mm. This component is designed for compact JCB construction machinery. The link pin (often working in the tipping link or H-link) is a crucial point in the bucket's kinematic system. Due to its location, it is constantly exposed to immense bending and shearing forces, as well as operation in a highly contaminated environment. The use of selected alloy steel ensures reliability, smooth operation of the attachment, and minimizes the risk of premature wear.
High shear and abrasion resistance: The pin has undergone rigorous heat treatment. The hardened outer coating guarantees extreme resistance to abrasion from dust and sand particles, while the flexible core protects the component against brittleness. As a result, the pin perfectly withstands the impact loads generated during material scooping and dumping.

Workshop Tip: The bucket link system is responsible for the correct dumping angle and closing force. Play on the link pin drastically reduces the smoothness of attachment movements and can lead to damage to the bucket cylinder through off-axis loads.
Golden rules for pin replacement:
1. Replace in pairs with bushings: Always verify the condition of the mating bushings. Installing a new pin into a worn, "egg-shaped" bushing will cause the pin to be point-supported, leading to its immediate wear or cracking under pressure.
2. Safe installation: Although the pin has a hard coating, striking its face directly with a steel hammer will cause the material to mushroom, damage the hardened layer, or prevent it from being properly inserted into the housings. Use only soft brass or copper drifts.
3. Proper lubrication: Before installation, coat the pin with a suitable grease (e.g., with molybdenum disulfide, MoS2). After assembly, remember to lubricate the system daily under pressure – fresh grease effectively flushes water and abrasive particles out of the joint.
