17/32" Steel Ball Set of 6 (Chuck Balls)

Kwik-Way 17/32” Steel Chuck Balls (Set of 6) - Essential for Centerline System Precision

This 17/32” Steel Ball Set of 6 (Chuck Balls) is a crucial replacement component for Kwik-Way valve refacer chucks, particularly those designed to fit a 7/32” Chuck. These hardened steel balls are fundamental to the precision and accuracy of the Kwik-Way “Centerline System,” found in models like the SVS II Deluxe Valve Refacer. The system uses two sets of three balls (totaling six) to air-activate and self-align, precisely gripping the valve stem to ensure the valve face is refaced concentric to its true center, achieving accuracy up to .0005 inches. Regular maintenance, including cleaning with denatured alcohol and lubricating with Automatic Transmission Fluid, is essential, as this set replaces lost or damaged balls, but not a worn chuck.

Kwik-Way 17/32” Steel Ball Set (Chuck Balls) - Core of the Centerline Precision System

The 17/32” Steel Ball Set of 6 (Chuck Balls) is an absolutely crucial replacement component for maintaining the unparalleled precision and accuracy of Kwik-Way valve refacer chucks. These hardened steel balls are fundamental to the renowned Kwik-Way “Centerline System,” a patented technology featured in high-performance models like the SVS II Deluxe Valve Refacer.

Purpose and Composition:

• Crucial Replacement: This set specifically provides six 17/32” steel balls, designed to replace any that may be lost or damaged during routine chuck maintenance or disassembly.
• Precision Components: Kwik-Way chucks rely on two sets of three hardened steel balls (totaling six balls) to create a highly precise gripping mechanism for the valve stem.

Function in the Centerline System:

At the heart of the Kwik-Way Centerline System, these steel balls within the chuck are designed to precisely grip the portion of the valve stem that travels inside the valve guide. This ingenious, air-activated, self-aligning six-ball chuck system automatically ensures that the valve stem is perfectly aligned. This critical alignment allows the valve face to be refaced concentric to its true center, eliminating run-out and greatly simplifying the valve refacing process by making stem chamfering or butt grinding before refacing unnecessary.

Unparalleled Accuracy:

The sophisticated design of the chuck, leveraging these steel balls, contributes significantly to the system’s remarkable accuracy:

• Achieves an accuracy of .0005 inches (0.0127 mm) with a standard chuck.
• Can reach an astounding precision of .0002 inches (0.00508 mm) when utilizing the optional High Performance Chuck.

The chuck system is versatile, accommodating valve stems ranging from 4mm to 14.3mm (0.157” to 0.5625”), with options for larger chucks to handle bigger valve stems.

Maintenance for Optimal Performance:

To ensure the continuous optimal performance and precision of your Kwik-Way chuck, regular maintenance is vital:

• Cleanliness is Key: It is essential to keep the chuck thoroughly clean and free of any debris, as even small particles can compromise its accuracy.
• Reinstallation: During chuck disassembly for cleaning, the small steel chuck balls may easily fall out. Exercise care during this process, and ensure all six balls are carefully reinstalled in their proper positions.
• Recommended Cleaning & Lubrication: Kwik-Way recommends using denatured alcohol for cleaning chuck parts to remove grease and grime, followed by lubrication with Automatic Transmission Fluid (ATF) to ensure smooth operation and protect components.

It is important to understand that while this set provides crucial replacement balls, it is not intended to restore the performance of a mechanically worn-out chuck. A chuck that has significant wear or damage may require a complete chuck replacement to restore full precision and functionality.
