The AB Tools 5 Ton Hydraulic Gear Bearing Puller is an essential tool for automotive technicians and DIY mechanics who need a reliable solution for removing stubborn gears, bearings, and pulleys. Its primary benefit is the hand-operated hydraulic system, which delivers controlled, high-force pressure to safely remove seized components without damaging shafts. While highly versatile due to its adjustable 2 or 3-jaw configuration, users should note that the 5-ton limit means it is not suitable for heavy-duty industrial machinery, but perfect for automotive or light equipment repair.

This tool is primarily designed for gears, pulleys, and bearings. It may not be suitable for steering wheels unless they are equipped with specific puller holes that align with the jaw spread.
The hydraulic unit is factory-sealed. We recommend avoiding disassembly, as it may void the integrity of the hydraulic seal.
The maximum reach is 5.5 inches (140mm).
AB Tools products typically carry a standard manufacturer's warranty against material defects; please verify with your specific retailer.
Yes, but it is highly recommended to apply a penetrating oil to the seized component and allow it to sit before applying hydraulic pressure to minimize the risk of breakage.
Check that the side-mounted release valve is fully closed. If it is closed and the issue persists, the hydraulic seals may require service.
Ensure the jaw adjustment bolts are tightened firmly and the jaws are seated securely behind the component edge before applying hydraulic pressure.
There may be air trapped in the hydraulic system. Cycle the pump fully while the ram is empty to bleed out air.
To set up the tool, assemble the desired jaw count (2 or 3) onto the forged yoke. Position the arms behind the gear or bearing and tighten the jaw adjustment bolts until secure. Ensure the side-mounted release valve is closed before pumping.
Compatibility: This tool has a maximum spread of 8 inches (200mm) and a maximum reach of 5.5 inches (140mm). Before starting, measure your target component to ensure it falls within these dimensions.
Care: After each use, wipe the ram clean of grit and metal shavings to prevent seal damage. Store the puller in the provided blow-molded case in a dry environment. Periodically inspect the forged arms for micro-fractures after high-stress applications.
