The inner and outer bushings of a hydraulic breaker act as the primary alignment barrier for the chisel shank. When worn beyond radial limits, they cause off-axis piston contact, severe cylinder scoring, and unexpected downtime. This maintenance guide breaks down common bushing failure modes—including galling, ovalization, and brittle cracking—and outlines a disciplined daily servicing protocol. Discover how correct vertical greasing using 3–5% Molybdenum Disulfide ($\text{MoS}_2$) grease and routine clearance checks extend the service life of your front head assembly, and learn how SLYM’s precision-forged bushings protect your carrier investment.
