2. Insufficient Force: Applying too little force when pulling a bearing can result in slippage or damage. Ensure you have a firm grip on the puller and apply steady, even pressure to avoid any mishaps.
3. Misalignment: Improper alignment of the puller can put unnecessary stress on the bearing and the puller itself. Always ensure that the puller is centered and aligned correctly before applying force.
4. Neglecting Safety Precautions: Bearing pullers can generate significant force, so it's crucial to wear appropriate safety gear such as gloves, safety glasses, and sturdy shoes. Never operate a bearing puller while under the influence of alcohol or drugs.

How to Use an OTC Bearing Puller

Using an OTC bearing puller is relatively straightforward. Follow these steps to ensure a safe and effective bearing removal:

1. Prepare the Bearing: Remove any external seals, shields, or retaining rings from the bearing to expose the race. Clean the bearing area to remove any dirt or debris.
2. Select the Appropriate Puller: As mentioned earlier, selecting the right puller for the bearing is crucial. Refer to the manufacturer's specifications to choose the puller that matches the bearing's size, type, and application.
3. Position the Puller: Place the puller over the bearing, ensuring that the jaws are centered and properly aligned with the bearing's outer race.
4. Tighten the Jaw Screws: Use a wrench to gradually tighten the jaw screws, applying even pressure to evenly distribute the pulling force around the bearing's outer race.
5. Apply Tension: Using the slide hammer or hydraulic pump, slowly and steadily apply tension to the bearing. Monitor the progress closely.
6. Remove the Bearing: Once the bearing is loose, gently tap the puller with a hammer or use the hydraulic pump to push the bearing off the shaft.
