Accurate depth measurement helps ensure proper liner positioning and uniform contact across the seating surface. This gauge supports consistent engine performance by reducing the risk of uneven liner support that can lead to sealing issues. Attributes:• Supports accurate liner seating by confirming depth values.• Reduces the risk of liner rocking caused by incorrect depth.• Provides clear depth readings for evaluation purposes.Applications: The Counterbore Tool Depth Gauge is used at the liner seat counterbore area during engine preparation work and measures the depth to confirm correct liner seating conditions.
