Q1: Why is my Kobelco SK75 excavator moving slowly even at high RPM?
A: This is often a sign of internal wear in the K3SP36C main pump. When the piston and cylinder block clearance increases, internal leakage reduces the flow rate. Replacing the pump or the rotating group can restore factory speeds.
Q2: How do I identify if I need the K3SP36C or a different model?
A: Check the nameplate on your current pump. The designation K3SP36C or K3SP36-C must be visible. Also, verify the number of mounting bolts and the spline count on the input shaft to ensure 100% fitment.
Q3: Why Choose This Hydraulic Pump?
A: Our units feature an OEM-standard tri-metal structure on the valve plate and cylinder block. This design is trusted by repair shops and equipment fleets worldwide for its durability in harsh construction environments.
