⚠️ Common Signs of Failure
- Drive trims slowly or unevenly
- Drive drifts down and will not hold position
- Hydraulic fluid leakage at the rod or end cap
- Pitted, bent or corroded piston rod
- Cylinder binds, knocks or fails to complete its travel
🛠️ Service Notes
- This is the starboard-side cylinder for DPH/DPR — the port-side equivalent is a separate, differently numbered cylinder, so confirm which side is being replaced before ordering
- A rebuild kit (dust seal, pressure seal, wiper, O-rings and end cap) is available if the cylinder is otherwise sound but weeping — bleed the trim system and check the fluid level after either a rebuild or a full replacement
