Product Description
PENN 1488824 L.C. Idler Gear (42C FTHII30LWLC)
Maintain the precision of your line counter system with the genuine PENN 1488824 L.C. Idler Gear. This specific component (Schematic ID: 42C) is a vital link in the gear train for PENN Fathom II and Squall II "Line Counter" (LC) models. It works in tandem with the drive system to ensure that your line depth is recorded accurately on the mechanical display while providing the necessary torque to the level wind assembly.
Engineered from high-impact, marine-grade composite materials, the 1488824 Idler Gear is built to resist the friction and heat generated during deep-trolling or heavy-duty bottom fishing. Replacing a worn or chipped idler gear is the best way to eliminate "skipping" in your line counter or uneven line lay on your spool.

Recommended Lubrication & Care
Because the idler gear is a high-cycle plastic-on-metal or plastic-on-plastic component, using the right lubricant is the difference between a smooth season and a stripped gear.
-
Primary Lube: Apply Deuthlon Reel Grease directly to the gear teeth. Its high-tack formula ensures the lubricant stays on the teeth rather than being slung off during high-speed retrieves.
-
Pivot Points: Use a single drop of Deuthlon Reel Oil on the gear post/shaft to reduce rotational friction and protect against salt-air intrusion.
Why Choose Genuine PENN Parts?
The 1488824 is a specialized gear with a specific tooth pitch and diameter unique to the Line Counter variants of the Fathom II and Squall II series. Using a standard idler gear (like the 42B) will not engage the counter mechanism correctly. Always use original PENN hardware to ensure your depth readings remain 100% accurate.
