Step-by-Step Guide: How to Use a 2-Jaw Reversible Gear Puller Safely

Introduction

A 2-jaw reversible gear puller is a versatile and essential tool for removing gears, pulleys, bearings, and other tightly-fitted components from shafts. The “reversible” design allows the jaws to be configured for internal pulling (from inside) or external pulling (from outside), making it extremely flexible. But to use it effectively—and safely—you need to follow proper procedures. In this guide, we will walk through how to use a 2-jaw reversible gear puller step by step, highlight key safety tips, and show how DNT Tools offers reliable, high-quality pullers built for both performance and safety.

Tools & Safety Preparation

  1. Inspect the Puller Before Use
    According to safety best practices, always examine the puller for visible defects—look for cracks, worn jaws, or bent arms. 

  2. Wear Protective Gear
    Use safety glasses (or a face shield) to protect your eyes from flying parts, and gloves to protect your hands. 

  3. Secure the Workpiece
    Make sure the gear, pulley, or bearing to be removed is firmly fixed (e.g., in a vice or stable fixture). A stable setup prevents movement during pulling

  4. Lubricate the Screw
    Apply a light penetrating oil or engine oil to the center screw before use to reduce friction and make the pulling process smoother. 

Step-by-Step Usage

Step 1: Set Up the Puller

  • Configure the jaws of the puller for the correct mode: internal pull or external pull. Many reversible pullers let you flip or reverse the hooks.

  • Adjust the jaw spread to appropriately match the diameter of the part you are removing.

  • Make sure the center screw is aligned with the shaft axis so that force will be applied straight. Misalignment can cause slippage or damage.

Step 2: Apply Force Gradually

  • Begin tightening the center bolt slowly using a wrench. Do not rush — applying steady, consistent pressure helps avoid damaging either the puller or the component. 

  • If the part is stuck, avoid over-torquing immediately. Instead, you can tap the screw head lightly with a hammer (square blows) to help jar the part loose. 

  • Maintain alignment throughout the process. If the puller begins to deform, stop and reassess.

Step 3: Remove the Component

  • Once the part begins to move, continue applying steady pressure until it comes free.

  • After removal, slowly back off the screw to release tension.

  • Remove the jaws carefully, and lift the gear / pulley / bearing off the shaft.

Key Safety Tips & Best Practices

  • Always use the correct puller size. An undersized puller may not grip correctly; an oversized one may apply too much force. 

  • Never use air-powered tools (like impact drivers) to drive the puller screw — this is discouraged for safety. 

  • If you notice any deformation of the tool (bent arms, stressed screw), stop work immediately. 

  • Place a cloth or protective cover over the workpiece to catch any potential flying parts. 

  • After use, clean the tool thoroughly (remove grease, debris) and store it in a dry place to prevent corrosion.
