Product Description
Mitchell 81707 Right Bearing – Genuine Replacement Part
The Mitchell 81707 Right Bearing is a precision-machined support component designed for the right-hand side (handle side) of Mitchell’s heavy-duty conventional and trolling reels. This bearing is critical for ensuring the smooth, concentric rotation of the spool and drivetrain under the immense pressure of fighting large saltwater or freshwater game fish.
Whether it is a high-grade bushing or a ball bearing assembly (depending on the specific reel generation), the 81707 reduces friction and prevents the shaft from scoring the side plate. Replacing a gritty or seized bearing is the most effective way to restore "free-spool" performance and ensure a silent, effortless retrieve.
Product Specifications & Compatibility
The 81707 Right Bearing is engineered to withstand high RPMs during casting or fast trolling and is a standard fit for the Mitchell 600 family’s robust architecture.
Compatible Models:
-
Mitchell 600 / 600A / 600AP
-
Mitchell 602 / 602A / 602AP
-
Mitchell 622 (Standard Saltwater)
-
Mitchell 624 (Large Capacity Saltwater)
-
Mitchell 600 Series Trolling Reels
Technical Note: In many vintage 600-series models, this bearing sits within a specialized housing in the right side plate. To ensure proper seating and to identify any necessary shims or retaining clips, please consult the high-resolution PDF schematics at www.reelschematic.com.
Technical Cross-Reference
To assist in sourcing through modern inventory systems or cross-referencing with secondary parts catalogs, this component is identified by the following alternate part numbers:
-
Alternate Part Number: 81707-1
Key Features
-
High-Load Durability: Built from materials (typically oilite bronze or high-grade stainless steel) chosen for their ability to resist deformation under heavy drag loads.
-
Corrosion Resistance: Specifically treated to handle constant exposure to salt spray and high-humidity marine environments.
-
Precision Fit: Machined to exact OEM tolerances to eliminate "spool play" and ensure perfect gear alignment.
-
Low Friction Design: Optimized to allow the spool to spin freely for maximum casting distance and smooth line release.
Maintenance & Lubrication Recommendation
Because the right bearing is located on the handle side, it is frequently exposed to moisture and salt travel through the handle shaft. We strongly recommend Deuthlon products for maintenance:
-
Deuthlon Reel Oil: For ball-bearing versions, apply 1-2 drops. This ultra-low-friction oil provides an immediate boost to spool speed and creates a protective film against salt crystals.
-
Deuthlon Reel Grease: For bushing versions (oilite), apply a light coating to the outer diameter where it seats into the side plate. Its "Aqua Shield" technology prevents the bearing from becoming "frozen" in the housing due to oxidation.
