The Piston Ring Groove Plug Gauge measures the width of piston ring grooves by allowing the internal groove dimension to be checked externally in a controlled manner. It helps technicians confirm that piston ring grooves are within acceptable limits during inspection and service activities. The gauge is positioned in the groove area to reference the exact groove width without relying on visual estimation. This allows measurements to be taken away from confined engine components for improved access and readability.Attributes:• Enables accurate checking of piston ring groove width during inspections.• Allows internal groove dimensions to be measured externally.• Supports proper measurement without dismantling surrounding components.Applications: The Piston Ring Groove Plug Gauge is located at the piston ring groove area, where it allows technicians to check groove width accurately by moving internal groove measurements outward for external reading.
