Product Description

Shimano 1048X Clutch Pawl Spring (BNT1800) – Genuine Replacement Part

Maintain the crisp, reliable engagement of your Shimano casting reel with the Shimano 1048X Clutch Pawl Spring (BNT1800). This genuine OEM replacement part is engineered to the exact specifications required to restore the tension and snap of your reel's clutch mechanism.

The clutch pawl spring is a critical internal component responsible for returning the clutch pawl to its proper position after the thumb bar is depressed. Over time, original springs can lose tension, corrode, or snap due to heavy use. Replacing a worn spring with the BNT1800 ensures your reel transitions smoothly between free-spool and gear engagement, preventing gear slippage and extending the life of your drivetrain.

Installation & Maintenance Tip:

When replacing internal springs, it is the ideal time to perform a full service on your reel’s linkage. To ensure maximum performance and longevity of your new clutch pawl spring:

1. Clean: Remove all old, oxidized grease from the clutch plate and pawl assembly.

2. Lubricate: We highly recommend using Deuthlon Reel Grease on the sliding surfaces of the clutch plate and the anchor points of the spring.

3. Oil: Apply a single drop of Deuthlon Reel Oil to the pivot pins to ensure lightning-fast engagement.

By using high-performance Deuthlon lubricants, you reduce friction on the spring’s contact points, preventing premature wear and ensuring a smooth "click" every time you engage the reel.

Why Choose Genuine Shimano Parts?

Generic springs often lack the precise tension required for Shimano’s tight-tolerance engineering. Using the authentic BNT1800 / 1048X spring guarantees that your thumb bar pressure remains consistent and your gears engage fully, protecting your pinion gear from rounding off during hook sets.
