Product Description
PENN 1488752 L.C. Idler Gear (42B FTHII30LW)
Keep your level wind system synchronized and reliable with the PENN 1488752 L.C. Idler Gear. This critical internal component (Schematic ID: 42B) is responsible for transferring power to the line carriage (L.C.) assembly, ensuring your fishing line is distributed evenly across the spool during every retrieve.
Manufactured from high-strength, wear-resistant polymers, this idler gear is designed to handle the torque of heavy-duty saltwater fishing while maintaining a quiet, smooth operation. A damaged idler gear can lead to uneven line stacking or a complete failure of the level wind mechanism; replacing it with this genuine PENN part restores your reel to its original factory performance.

Recommended Maintenance & Lubrication
Gears are the heartbeat of your reel. To prevent friction heat and premature tooth wear on the 1488752 Idler Gear, high-quality lubrication is essential.
-
Lube Recommendation: We strongly recommend applying Deuthlon Reel Grease to the teeth of the idler gear. Its high-adhesion formula ensures the grease stays on the gear even during high-speed casting or retrieving.
-
Additional Care: For the shafts and bushings supporting the gear, a drop of Deuthlon Reel Oil will provide a low-friction barrier that repels moisture and prevents salt buildup.
Why Use Genuine PENN Replacements?
The idler gear must mesh perfectly with the main gear and the worm shaft gear. Using the authentic 1488752 part ensures the pitch and diameter are exact, preventing "gear feel" or grinding. Trust PENN genuine parts to maintain the integrity of your Fathom II or Squall II reel.
