A hydraulic clearance puller is a specialized hydraulic maintenance tool used to remove tightly fitted bearings, gears, pulleys, sprockets, couplings, and other press-fitted components from shafts with minimal effort. It consists of a high-strength forged steel body, adjustable slim-profile jaws, a hydraulic ram or cylinder, piston, and a manual or integrated hydraulic pump. The hydraulic mechanism generates high pulling force, allowing components to be removed safely without damaging the shaft or surrounding equipment. Its compact jaw design enables operation in restricted spaces where conventional pullers cannot be used.

Operation:
To operate a hydraulic clearance puller, the jaws are adjusted and positioned securely behind the component to be removed, ensuring the hydraulic ram is centered on the shaft. The hydraulic pump is then actuated to build pressure, causing the ram to apply a steady pulling force that gradually separates the component from the shaft. Once removal is complete, the hydraulic pressure is released, the puller is removed, and the component is inspected. After use, the tool should be cleaned, checked for hydraulic leaks or damaged parts, lightly lubricated where necessary, and stored in a clean, dry place to maintain its performance and service life.
