Product Description
Mitchell 83792 Oscillation Gear – Genuine Replacement Part
The Mitchell 83792 Oscillation Gear (OSC Gear) is a vital internal component for modern vintage Mitchell rear-drag spinning reels. This gear drives the oscillation slide, converting the rotation of the handle into the vertical "up and down" movement of the spool.
A perfectly functioning oscillation gear is the secret to symmetrical line lay, which prevents line tangles (wind knots) and maximizes your casting distance. If your spool has stopped moving vertically or you feel a "skip" during the retrieve, replacing this gear is the standard solution to restore factory performance.
Product Specifications & Compatibility
The 83792 gear is precision-molded from high-durability composites designed to interface seamlessly with the main drive gear and the oscillation slider. It is specifically compatible with the "RD" (Rear Drag) series of Mitchell reels.

Technical Cross-Reference
You may find this part cataloged under these alternate manufacturer part numbers in modern inventory systems:
-
Alternate Part Number: 83792-1
Key Features
-
Friction-Reduction Design: Engineered to operate with minimal resistance against the reel body and slider.
-
Precision Teeth Geometry: Ensures a consistent mesh with the main gear to eliminate vibration.
-
OEM Reliability: A direct replacement part that meets original factory specifications for the RD series.
Maintenance & Lubrication Recommendation
Since the oscillation gear is a high-cycle part that undergoes constant friction, using the right lubricants is critical for longevity:
-
Deuthlon Reel Grease: Apply a small amount to the teeth of the gear and the center pivot point. This grease is formulated to stay on the gear even under high-speed retrieval, providing a waterproof barrier and ultra-smooth movement.
-
Deuthlon Reel Oil: Use one drop on the oscillation slide track that this gear drives. This ensures that the spool moves up and down with zero hesitation, even when using light lures.
