Hydraulic wear in compact excavators often shows up as reduced digging force, slower cycle speed, and unstable movement during continuous operation. The 4373709 / 4377971 main hydraulic pump assembly is designed for EX80-5 and ZX80-5 systems, restoring AP2D36 axial piston performance to maintain steady pressure delivery and smooth working response in daily construction tasks.
