Frequently Asked Questions (FAQs)
1. What does a puller set do?
A puller set is a tool used to remove various parts, such as bearings, pulleys, or gears from a shaft. It typically consists of legs that circle around the back or inside of a part, and a forcing screw that centers against the end of a shaft. This tool allows for safe and efficient removal of parts without causing damage.
2. What are the three types of pullers?
There are three main types of pullers:
- External bearing pullers, used when the bearing is mounted onto a shaft.
- Internal or blind bearing pullers, used when the bearing or component is fitted within a recess.
- Reversible bearing pullers, which offer versatility in pulling various components. Each type is designed for different pulling scenarios and offers unique features for specific applications.
3. What size puller do I need?
When choosing a puller, a general rule of thumb is that the center bolt diameter should be at least half the diameter of the shaft from which the object is being removed. However, the exact force needed for each pulling situation may vary, and it is best to consult the specific requirements and recommendations for the task at hand.
4. What does a 3 arm puller do?
A 3-arm puller is used for removing bearings and pulleys. It offers the ability to adjust each arm and has a two-sided structure that enables the removal of rings. This type of puller provides a reliable and efficient solution for various pulling applications.
5. What is an ultimate puller?
The Ultimate Puller is a tool designed to remove fan blade-blower wheels that are frozen to a motor shaft. It can be used to apply both pushing and pulling force and accommodates specific belt drive and direct drive motor shaft sizes. This versatile tool is a must-have for any toolbox.
6. What is a strong back puller?
A strong back puller, such as the SKF TMBS E, is a specialized tool used for dismounting bearings in applications where traditional jaw pullers cannot be used due to limited space or the need for a long reach. These pullers provide the necessary strength and flexibility to remove bearings in challenging situations.
7. What is a 3 jaw puller used for?
A 3-jaw puller is a versatile tool used to remove gears, pulleys, wheel hubs, and other hard-to-remove parts. It comes in various sizes and is an essential tool for any garage. The 3-jaw design provides a secure grip on the part being pulled, allowing for effective and safe removal.
8. Can I use a 3 jaw puller on a power steering pulley?
It is not recommended to use a 3-jaw puller or any other improper tools, such as hammers or shop presses, to remove a power steering pulley. Using the wrong tools can cause irreversible damage to the pulley, pump, or both. It is important to use a properly sized and designed pulley removal tool to ensure safe and damage-free removal.
