Product Description
Mitchell 81931 Bail Lock Spring – Essential Restoration Part
Ensure your vintage Mitchell reel operates with the mechanical precision it was designed for with the Mitchell 81931 Bail Lock Spring. This specialized spring is a vital component of the bail trip and locking mechanism, specifically tailored for the left-hand retrieve (right-hand wind) versions of Mitchell’s legendary high-speed and Match series reels.
A weak or broken bail lock spring can cause the bail to fail to lock open during a cast or prevent it from tripping closed automatically. Replacing this part restores the distinctive, crisp engagement that Mitchell reels are famous for.

Maintenance & Lubrication Recommendations
The bail locking mechanism is a high-friction area that requires specific lubrication to prevent premature wear and ensure lightning-fast bail release. For the best results, we recommend:
-
Deuthlon Reel Grease: Apply a thin layer to the contact points where the lock spring meets the trip lever. This grease stays put under the high-speed movement of the bail trip.
-
Deuthlon Reel Oil: Use a single drop on the spring’s pivot point to ensure it moves freely without binding.
To verify the exact placement of this spring within your rotor assembly, refer to the high-resolution PDF schematics available at www.reelschematic.com.
