The Reusability Valve Stem Gauge measures valve stem wear faster than a micrometer during inspection work. The gauge uses four accurately formed slots that match the most common valve stem diameters for quick checking. When the correct slot slides over the valve stem, excessive wear is confirmed, and reuse is not recommended. This method allows inspectors to identify worn valve stems without complex measurement steps. It supports reliable decisions during engine service by clearly indicating unacceptable valve stem wear.Attributes:• Uses fixed gauge slots to match common valve stem diameters.• Supports rapid inspection without complex measurement steps.• Helps determine whether valve stems are suitable for reuse.Applications: The Reusability Valve Stem Gauge is used during engine inspection, where it slides over valve stems to quickly confirm wear condition and determine whether valve stems can be reused safely.
