Follow us on Facebook for UpdatesA: A worn SBS120 Cylinder & Valve R is often the culprit. Scratches on the valve plate or cylinder block surface prevent a tight seal, causing internal leakage. We recommend checking these surfaces for any scouring or wear patterns.
A: It depends on hydraulic oil cleanliness and operating pressure. Typically, when performing a major engine rebuild or pump overhaul at 5,000-8,000 hours, the SBS120 cylinder block and pistons should be inspected and replaced if wear exceeds tolerances.
A: Our parts utilize an OEM-standard tri-metal structure which ensures superior heat dissipation and friction resistance. This specific configuration is trusted by repair shops & equipment fleets for its durability in harsh mining and construction environments.
