In an optical surface cylinder lubricating pump setting disc (setting position 1 to 6 will change the pump stroke). Wet liners have a thickness of 3mm to 6mm greater than dry liners because there is no supporting structure like a cylinder block. The diameters of cylinder liners were measured again prior to putting to use (following engine run-in), and then they were measured after ca. The manual method involves using micrometers and other Goltens deployed its technicians with LDM (Liner Diameter Measurement) tooling. Protrusion can be checked while the liner is held down by the installation tool. The difference in coolant cavitation caused by combustion The ovality kit is designed principally to measure cylinder liner wear and ovality. However, with the Chris-Marine Liner Diameter Measuring tool (LDM), the Seeing the liner in 3D reveals much more detail and understanding of the liner's wear pattern.
