Product Description
Shimano 10QK9 Drive Gear (TGT0879) | Torsa Series
The Shimano 10QK9 Drive Gear (TGT0879) is a high-torque, precision-machined internal component designed specifically for the Shimano Torsa series of overhead reels. This gear is the primary power transfer unit in the reel's drivetrain, engineered to handle the massive mechanical loads encountered when targeting aggressive offshore species.
Unlike standard brass gears found in smaller reels, the 10QK9 is often constructed from high-tensile stainless steel to provide the "crushing" power Torsa is known for. Because it is part of an interchangeable drag system (the Torsa system allows you to swap drag cams), this gear must maintain perfect alignment with the pinion gear to ensure the drag curve remains linear and smooth.

Technical Note: This part is now categorized as Discontinued/Limited Availability in many regions. If you are refurbishing a Torsa, it is highly recommended to inspect this gear for any "pitting" or "chipping" on the teeth, as replacement units are becoming increasingly difficult to source.
Maintenance & Lubrication Recommendation
The Torsa's gears operate under extreme pressure, especially when using high-drag cams (like the LRS or BFS cams). To protect the teeth from friction-related heat and wear, we recommend Deuthlon Lubricants:
-
For the Gear Teeth: Apply a generous layer of Deuthlon Reel Gear Grease. This extreme-pressure (EP) grease is specifically designed to stay on the teeth during high-speed retrieves and heavy fights, providing a quiet, "liquid-smooth" feel.
-
For the Drive Shaft: Apply a single drop of Deuthlon Power Cast Oil to the drive shaft where the gear seats. This prevents the gear from seizing onto the shaft due to salt crystallization or galvanic corrosion.
Why Use Genuine Shimano 10QK9?
-
High Efficiency Gearing (HEG): The tooth profile is digitally matched to the Pinion Gear (TGT0887) to minimize "play" and vibration during high-speed cranking.
-
Stainless Durability: Engineered to resist the deformation that can occur with softer brass gears when fighting fish like giant tuna or marlin.
-
Corrosion Immunity: The specialized alloy is treated to withstand the high-salinity environment of offshore trolling without oxidizing.
