KWIK-WAY Valve Stop Rod

Product Details

Kwik-Way Valve Stop Rod (Tool) - Essential for Precision Setting and Machine Maintenance

The Valve Stop Rod is a crucial tool for Kwik-Way valve refacers, explicitly listed as part of the Base Assembly and provided as standard equipment on all Kwik-Way Valve Refacers. This versatile rod serves two primary functions: it is used to precisely position the internal Valve Stop component within the valve centerline chuck, ensuring consistent valve stem length vital for applications like “Non-Adjustable” valvetrains. Additionally, this rod is utilized to lock the main spindle shaft, which is essential during procedures such as grinding stone replacement. Its inclusion ensures that every Kwik-Way refacer is equipped for accurate grinding and safe maintenance.

The Valve Stop Rod is a tool specifically designed for Kwik-Way valve refacers, forming an integral part of the machine’s Base Assembly. This rod is instrumental in ensuring meticulous setup and safe maintenance operations, and is provided as standard equipment on all Kwik-Way Valve Refacers.

Dual Functions of the Valve Stop Rod:

This specialized rod serves two critical functions within the Kwik-Way valve refacing system:

Precise Positioning of the Internal Valve Stop:

• The Valve Stop Rod is specifically used as a tool to push and accurately seat the internal “Valve Stop” component (a distinct part from this rod) inside the hollow chuck shaft.
• This internal Valve Stop then provides a consistent rest for the valve face, ensuring that the valve stem is placed into the V-Block Assembly (Part Number 012-0160-00) in the exact same location for every valve.
• This consistent positioning is paramount for achieving precise valve stem lengths, especially vital for engines with “Non-Adjustable” valvetrains where exact and uniform valve stem length is critical for proper engine operation and valve lash.
• Usage: To set the internal valve stop, a valve is first installed in the chuck at the desired depth, the chuck is allowed to close, and then this 3/16” diameter Valve Stop Rod is used to push the internal valve stop in until it is firmly seated against the valve stem end. Operators must ensure subsequent valves are pushed in far enough to consistently contact this internal stop.

Main Spindle Locking for Grinding Stone Replacement:

• Beyond setting the valve stop, this rod also serves as a crucial locking tool for the main spindle shaft. This function is particularly important during maintenance procedures, such as grinding stone replacement, where securely locking the spindle prevents rotation and ensures safety and stability for the operation.

Integration with the Centerline System:

The precise setting of the internal Valve Stop (facilitated by this rod) works in conjunction with the chuck’s advanced “Centerline System.” This air-activated, self-aligning system utilizes two sets of three hardened steel balls to grip the valve stem, automatically aligning it and allowing the valve face to be refaced concentric to its true center. This rod is the key tool that helps establish the initial consistent reference point for this high-precision system.

Standard Equipment for All Kwik-Way Valve Refacers:

As a testament to Kwik-Way’s commitment to precision and ease of maintenance, the Valve Stop Rod is provided as standard equipment on all Kwik-Way Valve Refacers. This ensures that every machine comes equipped with this essential tool for accurate valve stop positioning and critical spindle locking, enhancing the overall functionality and safety for operators.

Important Note on the Internal Valve Stop: It is important to remember that the actual internal Valve Stop component is housed inside the hollow chuck shaft and is distinct from this Valve Stop Rod (the tool). When replacing a chuck assembly, it is crucial to carefully remove the existing internal Valve Stop from the old chuck and correctly insert it into the new chuck, then use this rod to set its position.

By utilizing the Valve Stop Rod, rebuilders can ensure consistent valve stem grinding and safely perform critical machine maintenance, contributing to the overall accuracy and longevity of valve train components.
