Product Description
Hardy 1329020 HEUD010SP05 Spindle
The Hardy 1329020 Spindle (Style No: HEUD010SP05) is the central axle designed for the Hardy Ultralite DD (Disc Drag) series of fly reels. This precision-engineered spindle serves as the main shaft upon which the spool rotates and the disc drag system is mounted. It is the core structural element that ensures the spool remains perfectly centered and stable under the heavy torque of a running fish.
Machined to microscopic tolerances, this spindle is crucial for the "zero-play" performance that the Ultralite DD series is known for. Over time, a spindle may require replacement if it becomes scored from grit or bent due to accidental impact, both of which can lead to spool wobble or inconsistent drag pressure.

Key Features
-
Reduced Weight Design: Specially hollowed or tapered to align with Hardy’s "Ultralite" philosophy without sacrificing structural strength.
-
Micro-Polished Finish: Features a low-friction surface that minimizes wear on the internal spool bearings and one-way clutch assembly.
-
Precise Threading: Engineered for a rock-solid seat within the reel back (frame), preventing mechanical drift during high-speed payouts.
-
Saltwater Resistant: The materials are selected to withstand the corrosive effects of brackish and marine environments, provided proper maintenance is followed.
Maintenance & Lubrication
The spindle is the primary friction point between the frame and the rotating spool. To ensure the longest life for your reel and to keep the retrieve silent, we recommend using Deuthlon lubricants:
-
Base Protection: Apply a thin layer of Deuthlon Power Grease to the base of the spindle where it threads into the frame. This prevents the metal from "seizing" due to moisture entrapment.
-
Bearing Surface Care: Use a single drop of Deuthlon Reel Gear Oil along the shaft of the spindle where the spool bearings and one-way clutch make contact. This polarized oil stays bonded to the shaft, ensuring a buttery-smooth rotation and reduced start-up inertia.
