Product Description
Shimano 10FVD Bail Spring (RD10753)
The Shimano 10FVD Bail Spring (RD10753) is a critical tension component located inside the bail arm assembly of Shimano spinning reels. It is responsible for providing the "snap" that holds the bail wire in the open position during a cast and forces it back into the closed position when you begin your retrieve.
In modern Shimano architecture, this is typically a compression-style coil spring. Over time, these springs can lose their tension ("fatigue") or snap due to internal corrosion from saltwater trapped under the bail cover. If your bail arm feels "limp," fails to stay open during a cast, or won't click back into place, this spring is the most likely culprit.

Key Features
-
High Elasticity: Made from tempered stainless steel designed to withstand thousands of "open-close" cycles without losing its original length.
-
Corrosion Resistant: Specifically treated to resist the "pitting" that occurs when saltwater sits inside the bail arm housing.
-
Precision Length: Calibrated to work perfectly with the Bail Spring Guide (RD10754) to prevent the spring from buckling under pressure.
-
Direct OEM Fit: Guaranteed to provide the exact factory "click" and resistance levels for the listed reel models.
Maintenance & Installation Tips
-
Don't Forget the Guide: When replacing the spring, ensure the Bail Spring Guide (plastic pin) is inserted correctly inside the coil. Without the guide, the spring will bend sideways and jam the bail arm.
-
Lubrication: Do not use heavy grease here. A light coating of water-resistant grease (like Shimano DG06) is all that’s needed to prevent corrosion. Too much grease will attract sand and slow down the bail's snap action.
-
The "Flying Spring" Warning: When removing the bail arm cover, keep your thumb over the spring. It is under tension and can easily fly out and be lost.
Pro Tip: If you replace the spring and the bail still feels sluggish, check the Bail Trip Lever and the Bail Arm itself for salt buildup or sand. Often, the friction isn't from a bad spring, but from "gunk" trapped in the hinge. You can find the exact assembly order in the PDF schematics at www.reelschematic.com.
