The Sealey PS984 is a comprehensive mechanical bearing separator puller set designed for removing bearings, gears, and pulleys in professional workshop environments. This versatile tool kit includes two mechanical separators covering diameter ranges of 25-50mm and 45-75mm, making it suitable for a wide variety of component sizes commonly encountered in engineering, automotive, marine and agricultural applications. The set features a robust single yoke design with a 170mm thrust bolt that provides reliable mechanical advantage for separating seized or tight-fitting components. The inclusion of multiple extension bars in varying lengths (60mm, 85mm, 90mm, and 115mm pairs) along with a 160mm cross beam allows technicians to configure the tool for different working scenarios and component access requirements. The smaller separator offers a maximum reach of 220mm, while the larger 45-75mm unit extends to 170mm, providing flexibility for different removal tasks. Ideal for mechanics, engineer
