Product Description
Mitchell 81415 Oscillation Slide – Genuine Replacement Part
The Mitchell 81415 Oscillation Slide (also known as the Cross Block) is a critical internal component that governs the spool's vertical travel. This part acts as the bridge between the oscillation gear and the axle, converting rotational energy into the steady "up and down" movement required for a perfect line lay.
A worn or damaged oscillation slide can lead to "stacked" line at the top or bottom of the spool, causing wind knots and significantly reducing casting distance. Replacing this part ensures your vintage Mitchell reel maintains its legendary mechanical precision and smooth operation.
Product Specifications & Compatibility
The 81415 Oscillation Slide is engineered to fit Mitchell’s heavy-duty and saltwater spinning reel series. It is built to withstand the high torque and heavy drag pressures associated with large-game fishing.

Key Features
-
High-Strength Alloy Construction: Designed to resist the "pounding" motion of the oscillation gear under heavy loads.
-
Precision Machined Track: Ensures a smooth, jitter-free glide for the oscillation gear pin.
-
OEM Fitment: A direct drop-in replacement that maintains original factory tolerances for spool stroke length.
-
Saltwater Grade: Materials chosen for their ability to resist corrosion in harsh marine environments.
Maintenance & Lubrication Recommendation
The oscillation slide is a high-friction "sliding" part that requires consistent lubrication to prevent metal fatigue. We recommend Deuthlon products for maximum protection:
-
Deuthlon Reel Grease: Apply a thin, even coating to the internal track where the oscillation gear pin resides. Its "Aqua Shield" technology prevents salt and moisture from causing grit buildup.
-
Deuthlon Reel Oil: Use one drop on the guide rails where the slide moves against the reel body. This ensures the oscillation remains effortless and silent, even during a high-speed retrieve.
