Product Description
Shimano 10NXL Idle Gear (D) (TGT0587) | Tekota 700 & 800 Series
The Shimano 10NXL Idle Gear (D) (TGT0587) is a vital internal transmission gear found in the largest frames of the Shimano Tekota series. It serves as the final link in the "Idle Gear Train," transferring rotational energy from the main drive gear specifically into the level wind worm shaft.
This gear is precision-molded from a high-density, self-lubricating polymer. Like its counterparts in the Tekota drive system, it is engineered to act as a mechanical fail-safe. In the event of a severe level wind jam or line guide obstruction, this plastic gear is designed to strip its teeth. This intentional sacrifice protects the much more expensive metal drive gears and the reel's structural frame from catastrophic torque damage.
Product Specifications

Compatible Reel Models
The 10NXL (TGT0587) is sized specifically for the heavy-duty, high-capacity Tekota frames. It is a direct fit for:
-
Shimano Tekota 700 (TEK700)
-
Shimano Tekota 700LC (Line Counter)
-
Shimano Tekota 800 (TEK800)
-
Shimano Tekota 800LC (Line Counter)

Technical Note: This gear is physically larger than Idle Gear D (TGT0541) used in the 300/500/600 series. While the letters are the same, they are not interchangeable across frame sizes. Ensure your reel is a 700 or 800 size before installation.
Maintenance & Lubrication Recommendation
Because this gear is the primary point of resistance at the end of the idle train, it is susceptible to friction heat. Proper lubrication ensures quiet operation and prevents the polymer from becoming brittle. We recommend Deuthlon Lubricants:
-
For the Gear Teeth: Apply a light, even coating of Deuthlon Reel Gear Grease. This grease is safe for polymers and provides a high-tack moisture barrier, ensuring the level wind stays synchronized and silent even under heavy trolling loads.
-
For the Support Pin: Apply a single drop of Deuthlon Power Cast Oil to the Idle Gear D Support (TGT0588). This ultra-low viscosity oil reduces rotational drag, which is essential for maintaining the "Shimano Smooth" feel during the retrieve.
Why Choose Genuine Shimano 10NXL?
-
Precision Timing: The exact tooth count is required to keep the Line Counter accurate; aftermarket gears with slight variations can cause depth readings to drift significantly over 100+ feet.
-
Failure Calibration: Shimano’s polymer blend is specifically rated to shear at a precise torque level, ensuring it breaks before your main gear does.
-
Thermal Stability: Engineered to maintain its shape and hardness across a wide range of temperatures, from freezing winter Great Lakes trolling to hot summer offshore conditions.
