🔌 Function

⚠️ Common Signs of Failure

• Assembly creeping or sagging under load when it should hold
• Rod pitted, scored or bent
• Slow, jerky or uneven movement
• Fluid level dropping with no external leak found elsewhere

🛠️ Service Notes

• Cylinder 3857471 is only 23 grams heavier and shares the same name and family, so the published weight cannot separate the two — order by part number and by which application it belongs to
• Extend and retract it fully to purge air after fitting, and check the fluid level again once the air has settled out
• Protect the rod from knocks and salt while it is off the boat
