Product Description

Here is the detailed product description for the Shimano 105HJ Drive Shaft (BNT3077).

SHIMANO 105HJ DRIVE SHAFT (BNT3077)

The Core of the "Total Efficiency" System

The Shimano 105HJ Drive Shaft (Part No. BNT3077) is the main structural post for the handle assembly of the Shimano Calcutta TE (Total Efficiency) series. Precision-machined to support Shimano’s HEG (High Efficiency Gearing), this shaft anchors the oversized main gear and drag stack that give the Calcutta TE its legendary cranking power.

Because the TE series is designed for torque, this shaft endures significant stress. If your handle wobbles, the threads are stripped from overtightening the nut, or the shaft is bent from a drop, replacing it is the only way to restore the smooth, wobble-free rotation of this premium round reel.

Installation Tip: The Drive Shaft is secured to the reel frame by a Drive Shaft Retainer plate and two screws. When installing, ensure the base bearing (often size 5x11x4mm) is clean and seated fully. You will also need to transfer the Anti-Reverse Ratchet (the toothed washer at the bottom) to the new shaft; ensure the "teeth" of the ratchet are facing the correct direction for the pawl to engage.
