Shimano 10ty4 Anti-reverse Cam Spring

Product Description

The SHIMANO 10ty4 is an anti-reverse cam spring, a small internal component used in Shimano fishing reels to maintain directional control of the rotor. The cam spring engages the anti-reverse mechanism, preventing the rotor from spinning backward during retrieval. This type of component is typically replaced during a reel rebuild or when the anti-reverse function becomes inconsistent or fails entirely. Installation is performed by fishing reel technicians or experienced anglers comfortable with precision disassembly of reel internals.

This part is suited for reel service and repair applications where the original anti-reverse cam spring has worn, fatigued, or become damaged. It restores proper one-way bearing or cam-style anti-reverse function in the affected reel. Reel servicing of this type is common in both freshwater and saltwater applications where internal components are subject to corrosion, debris ingestion, or wear over time.

Key Features

• Designed as a direct OEM replacement anti-reverse cam spring
• Restores consistent anti-reverse function in compatible Shimano reels
• Small-format precision component suited for reel rebuild and maintenance
• Genuine Shimano part for accurate fitment and reliable performance

Compatibility

Designed as an OEM-style replacement cam spring for compatible Shimano fishing reel models. Refer to the Shimano parts diagram for your specific reel model to confirm fitment before installation.

Installation Notes

Installation should be performed by a qualified reel technician or an experienced user familiar with reel disassembly and reassembly procedures. Full spool and rotor removal is typically required to access the anti-reverse cam mechanism. Use appropriate reel-safe lubricants upon reassembly and avoid over-tensioning small internal springs during installation. Consult the Shimano exploded parts diagram for your reel model to ensure correct spring orientation and seating.
