JCB Front Loader Arm Pin (Interlever) 44.5x166mm
Hardened front loader arm pin, designed for the front loader equipment of JCB machinery. This component is a connecting element in the self-leveling and front arm kinematics mechanism. Precision-engineered from high-grade heat-treated steel, the pin features excellent shear resistance and high surface hardness, minimizing wear under heavy load conditions.
Specifications and Technical Parameters:
- Diameter: 44.5 mm.
- Working/Total Length: 166 mm.
- Material: Hardened steel (crack and wear-resistant).
- Application: Interlever mechanism (front loader arm linkage).

Technical Advice: The Interlever system is responsible for load stability in the bucket while the arms are being lifted. A worn 44.5mm pin at this point causes imprecise self-leveling and annoying clunking sounds. When replacing the pin, it is absolutely recommended to install new bushings—seating a new pin in worn, oval-shaped bushings will lead to its premature point wear. During installation, check the patency of the grease channels in the arm to ensure a constant supply of fresh grease to the pin.
