Penn 1313878 Main Shaft Assembly

Product Description

The PENN 1313878 is a main shaft assembly designed as a direct replacement component for PENN reels. The main shaft is a core internal part that transmits rotational force from the rotor to the spool, enabling line retrieve during operation. This assembly is intended for technicians and service professionals who perform reel maintenance, rebuild, or warranty repair work. Proper fitment of the main shaft is critical to smooth drag engagement and consistent spool oscillation.

This assembly is used in reel servicing applications where the original main shaft has worn, bent, or otherwise failed. It is suited for repair shops, tackle service centers, and experienced anglers performing their own maintenance. Installation requires disassembly of the reel body and removal of the existing shaft before the replacement unit can be seated and aligned correctly.

Key Features

• Direct OEM-style replacement for the original PENN main shaft assembly
• Restores rotor-to-spool power transmission on worn or damaged reels
• Maintains factory fit and dimensional tolerance for proper drag and oscillation function
• Designed for use by reel service technicians and experienced repair personnel

Compatibility

Designed as an OEM-style replacement main shaft assembly for compatible PENN reels. Confirm model fitment against the PENN parts diagram for your specific reel before installation.

Installation Notes

Installation should be performed by a qualified reel technician familiar with PENN reel disassembly procedures. Power-assisted or motorized tools are not applicable to this repair; standard reel servicing hand tools are used. Ensure the reel is fully depressurized of drag tension and the spool is removed before accessing the main shaft. Refer to the PENN service manual for your specific reel model to confirm correct shaft seating and rotor alignment.
