Question 1

What is the SATA ST90640 3-Jaw Reversible Puller 10" best used for?

Accepted Answer

It's a professional 3-jaw puller designed for both internal and external pulling tasks. The reversible jaws allow you to grip bearings, gears, bushings, and similar components from the inside or outside, making it versatile for automotive, maintenance, and workshop applications.

Question 2

How does the reversible jaw design work for internal vs external pulling?

Accepted Answer

The tool features jaws that can be oriented to bite from the inside or the outside of a component. This lets you switch between internal pulls (pulling a bearing from inside a bore) and external pulls (pulling a gear or pulley from the outside) without needing a separate tool.

Question 3

What materials and finishes are used on the ST90640, and why do they matter?

Accepted Answer

The puller is made from high-quality steel and is heat-treated for durability, ensuring it can handle tough pulling jobs without bending. It also includes a phosphate coating on the spindle to resist corrosion in challenging working environments, helping extend tool life.

Question 4

What are the key features and attributes of this puller?

Accepted Answer

Key features include reversible jaws for internal/external pulling, precision-machined threads and jaws for smooth operation, adjustable jaws to fit different bearing or gear sizes, an ergonomic handle for comfortable use, anti-rust coating for longevity, a compact design for portability, and a safety-oriented design to reduce slippage during operation.

Question 5

What applications is this puller suited for?

Accepted Answer

It's ideal for automotive and mechanical tasks such as removing bearings, gears, pulleys, sprockets, and other press-fit components where a balanced, controlled pull is needed. The adjustable jaws make it adaptable to a range of component sizes.

Question 6

How do I install and use the ST90640 puller?

Accepted Answer

1) Secure the puller to the component with the appropriate jaw position (internal or external). 2) Center the puller using the pilot point on the screw tip to ensure accurate alignment. 3) Turn the screw or handle smoothly to apply pulling force, keeping the jaws aligned with the component to avoid slipping. 4) Stop if the component begins to bind or if unusual resistance is felt, then reassess alignment and seating.

Question 7

Are there any maintenance tips to extend the life of this puller?

Accepted Answer

Keep the threads clean and lightly lubricated to ensure smooth operation. Wipe away dirt and moisture after use, and store in a dry place to preserve the anti-rust coating. Periodically inspect the jaws for wear and ensure the pilot point remains sharp for accurate centering.

Question 8

What safety considerations should I follow when using this puller?

Accepted Answer

Always wear eye protection and gloves. Ensure the puller is properly seated on the component and that there is even contact with all jaws. Avoid side loading, over-tightening, or using the tool on components that exceed its designed capacity. If you feel excessive resistance, stop and recheck alignment and seating.
