OEM Bucket Cylinder for Komatsu PC5500 (ref. 992 125 40)
A bucket cylinder is the hydraulic actuator that curls the bucket to generate breakout force during digging. Cylinders typically wear at the rod seals and the chrome-plated rod surface; internal leakage shows up as cylinder drift or slow movement, and contamination or rod scoring accelerates seal wear.
