What are some safety tips for using gear pullers?
Gear pullers are made in various shapes and sizes and have many uses. Always use the correct tool for the job.
- Wear safety glasses or goggles, or a face shield (with safety glasses or goggles).
- Select the proper gear puller for each job. Always use a gear puller of the required size or larger. Use a 3-jaw puller, if possible.
- Ensure that the gear puller is aligned with the shaft and fits tightly around the part to be removed. The jaws should be parallel with the screw. This assures a straight pull.
- Be careful when removing a stubborn gear or bearing. Always strike the head of the centre screw squarely. If after two sharp blows the gear or bearing remains stuck, select a larger puller and proceed to remove the gear or bearing.
- Use a protective cap or removable point to protect screw from mushrooming or splitting.
- Stop work if the gear puller starts to deform.
- Cover work with a cloth to protect you and by-standers from flying parts.
- Lubricate the centre screw with machine oil before use.
- Clean the gear puller after use and store it in a dry place.
What are some things that I should avoid doing?
- Do not use air powered tools on gear pullers.
- Do not use any puller with functioning parts that show excessive wear, dents, or cracks. Inspect the centre screw for signs of galling or seizing.
- Do not heat any gear puller. It will lose its strength and break under pressure if heated.
- Do not cut or grind any part of a gear puller.
