4C-8246: Lug Back Dial Indicator

The Lug Back Dial Indicator allows technicians to accurately measure the existing valve clearance, which is the gap between the valve stem and the valve train component. This measurement is then compared to the manufacturer's recommended valve clearance specification. If the clearance is outside the specified range, adjustments can be made to the valve train components to bring the clearance back within the proper tolerance. Attributes: • Manufactured to precise specifications and are built for durability and reliability • Used to measure the linear movement of the valve stem Applications: The Lug Back Dial Indicator is mounted onto a fixed surface, such as the engine block, cylinder head, or a dedicated fixture. The spindle or contact point of the dial indicator is positioned to rest against the valve stem. As the engine is rotated, the dial indicator measures the linear displacement of the valve stem, which corresponds to the valve clearance.
