Mitchell 81186 Side Plate – Genuine Replacement for 300C Series
Upgrade or repair your vintage spinning reel with the Mitchell 81186 Side Plate. This specific side cover is engineered for the "C" series of the legendary Mitchell 300 lineup. The "C" designation signifies a specialized internal design equipped with ball bearings in the handle axis and rotor, requiring a side plate with a precise bearing sleeve housing that differs from standard 300 models.
This genuine Mitchell component is essential for maintaining the alignment of the drive gear and ensuring the smooth, low-friction performance that characterizes the 300C high-performance series.

Maintenance & Lubrication Excellence
Precision bearing reels like the 300C require superior lubrication to protect the increased number of moving parts. To keep your reel operating at its highest potential, we recommend the following:
-
Main Drive Gear & Bearings: Apply Deuthlon Reel Grease directly to the gear teeth and the bearing seat. Its specialized formula provides a protective barrier against moisture and ensures the planetary gear system remains silent and efficient.
-
Handle Shaft & Pivot Points: Use Deuthlon Reel Oil for the handle axis and the anti-reverse lever. This ultra-light lubricant penetrates deep into the bearings, reducing startup inertia and providing instant engagement.
Why Choose the 81186 Side Plate?
The side plate is the foundation of your reel's structural "box." A genuine Mitchell 81186 ensures that the ball bearings remain perfectly perpendicular to the drive gear. Using the correct plate prevents "gear binding" and premature bearing wear, preserving the unique "C" series feel that collectors and anglers prize.
