The 3 arm puller is a commonly used tool in the automotive industry for removing parts that are stuck or pressed onto a shaft, such as gears, pulleys, and bearings. Here are some specific examples of how 3 arm pullers are used in the automotive industry:
1.Removing Steering Wheels: In some cases, the steering wheel of a vehicle can become stuck on the steering column. A 3 arm puller can be used to remove the steering wheel by attaching the arms of the puller to the wheel and applying pressure to pull the wheel off the column.
2.Removing Bearings: Bearings can become stuck or seized onto a shaft, making them difficult to remove. A 3 arm puller can be used to remove the bearing by attaching the arms of the puller to the outer edge of the bearing and applying pressure to pull it off the shaft.
3.Removing Pulleys: Pulleys are often press-fitted onto a shaft and can be difficult to remove without damaging the pulley or the shaft. A 3 arm puller can be used to remove the pulley by attaching the arms of the puller to the outer edge of the pulley and applying pressure to pull it off the shaft.
4.Removing Axles: In some cases, an axle can become stuck in the hub or differential housing. A 3 arm puller can be used to remove the axle by attaching the arms of the puller to the axle and applying pressure to pull it out of the hub or differential housing.
5. Removing Gears: Gears can become stuck onto a shaft due to corrosion or other factors. A 3 arm puller can be used to remove the gear by attaching the arms of the puller to the gear and applying pressure to pull it off the shaft.
3 arm pullers come in different sizes and shapes and are designed for specific applications. For example, some 3 arm pullers have reversible jaws that can be used for internal or external pulling, while others have adjustable arms that can be set to different lengths. Choosing the right type of puller for the job is important to ensure safe and efficient removal of the part.
When using a 3 arm puller, it is important to take certain precautions to avoid damaging the part being removed or the puller itself. The followings are common mistakes to avoid :
1.Using the wrong size puller: Using a puller that is too small or too large for the job can cause damage to the part being removed or the puller itself.
2.Not positioning the arms evenly: Uneven pressure can cause the part to become damaged or the puller arms to bend or break.
3.Over-tightening the central threaded rod: Applying too much pressure by over-tightening the central threaded rod can cause damage to the part being removed or the puller itself. Always tighten the rod slowly and evenly.
4.Not using lubrication: Applying lubrication to the part being removed can make it easier to remove and reduce the risk of damage. Always apply the appropriate lubrication to the part before using the puller.
5.Not taking appropriate safety precautions: Using a 3 arm puller can be dangerous if appropriate safety precautions are not taken. Always wear appropriate personal protective equipment (PPE).
6.Using a damaged or worn puller: Always inspect the puller before use and replace it.
