Why Replace the Cylinder Liner?
Over extended use, the liner can become worn, scratched, or lose its inner roundness from repeated impact. This degrades hammer efficiency, increases internal friction, and accelerates wear on the piston and seals. Installing a new OEM liner restores precise dimensional control for optimal power transfer, lower vibration, and enhanced lifespan of the tool.
