The ATC6434 Universal Liner Height & Counterbore Depth Gauge is a versatile, high-precision measuring tool designed for heavy-duty engine rebuilds and machining. It enables technicians to accurately assess both liner protrusion (liner height) and counterbore depth, two critical dimensions in diesel engine block preparation and cylinder liner installation.
Built to accommodate a wide array of diesel engine blocks this universal gauge provides the flexibility to measure:
-
Cylinder liner height above the deck (liner protrusion)
-
Counterbore ledge depth, ensuring proper liner support
-
Occasionally piston-to-deck height or top dead center verification (when used with appropriate contacts)
Features include:
-
Stable base (sled) for consistent reference surface
-
Interchangeable contacts: pointed for liner height, flat for counterbore depth
-
Graduated dial (in the referenced equivalent version) for incremental measurement resolution
This tool is ideal for engine remanufacturing shops, heavy-duty diesel rebuild operations, and maintenance facilities where accurate liner and deck geometry is essential for sealing integrity and longevity. By using the ATC6434, you help ensure that your liners are properly seated, supported by the ledge, and that your deck geometry is in spec—reducing head gasket failures, liner misalignment, and thermal sealing issues.
