The Deck Checking Tool provides an accurate measurement of the cylinder block top surface to determine how much material has been removed during previous machining work. It is useful during engine reconditioning because it helps technicians understand the current deck height condition. It helps compare measured values against block specifications to identify earlier machining activity. This process supports correct planning for further machining or assembly decisions.Attributes:• Measures the cylinder block deck height with high accuracy.• Supports comparison of actual measurements with block specifications.• Helps determine the remaining material on the block's top surface.Applications: The Deck Checking Tool functions during engine inspection and reconditioning processes. The tool measures the cylinder block top surface to verify equipment history and the current deck height condition.
