OEM Stick Cylinder for Komatsu PC3000 (ref. 992 055 40)
A stick (arm) cylinder is the hydraulic actuator that extends and retracts the stick, controlling reach and crowd motion 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.
