An Inspection Spacer Tool is used to assess the contact areas of the liner O-ring in both the upper and lower sections of a cylinder block. This tool ensures that the O-rings are properly seated and making full contact to maintain the integrity of the engine’s sealing system. By accurately checking these contact areas, the tool helps identify potential issues such as gaps, misalignment, and wear that otherwise lead to leaks and improper sealing.Attributes:• Ensures full and even contact between O-rings and cylinder block.• Reduces the risk of engine failure due to improper sealing. Applications: An Inspection Spacer Tool is used within the cylinder block to verify the liner O-ring contact areas, ensuring proper sealing in both the upper and lower sections.
