This technical guide from SLYM Machinery details the precise maintenance protocols required to eliminate hydraulic breaker piston scoring (surface scratching and galling). Operating under extreme thermal and mechanical stress, a breaker's power cell is highly vulnerable to lubrication starvation and misalignment. This article provides a veteran mechanic's step-by-step approach—covering correct vertical positioning during greasing, strict 2-hour MoS2 lubrication intervals, weekly bushing clearance measurements, and hydraulic oil temperature management—to maximize uptime, protect internal components, and lower the total cost of ownership (TCO) for fleet managers.
