Hardy GTS500

The Hardy GTS500 is a popular cassette-style fly reel known for its lightweight design and quick-change spool system. Because it uses a synthetic disc drag system, maintenance is generally straightforward, focusing on cleanliness and lubrication.

Tools and Preparation

Before starting, clear a clean workspace. Small springs and clips can easily be lost.

• Tools needed: Small flat-head screwdriver, isopropyl alcohol, cotton swabs, and high-quality reel grease (e.g., Penn Precision or Loctite).

• Note: Avoid using WD-40 or heavy motor oils, as these can degrade the synthetic drag components.

Step 1: Spool Removal and Basic Cleaning

1. Release the Spool: Press the quick-release lever located on the front of the spool. Pull the spool straight off the frame.

2. Cassette Inspection: If you are changing lines, pop the clear plastic cassette out of the metal spool carrier. Check the carrier for any dents or grit.

3. Debris Removal: Use a cotton swab dipped in alcohol to wipe the internal rim of the frame and the central spindle.

Step 2: Accessing the Drag System

The GTS500 utilizes a captive drag knob, but the internal assembly requires care.

1. Remove the Retaining Cap: On the spindle, there is usually a small O-ring or a screw-on retaining nut. Carefully unscrew this to release the drive gear and the one-way bearing.

2. One-Way Bearing: This is the "clutch" that allows the reel to spin freely in one direction and engage the drag in the other.

   • To Change Retrieval (Left to Right): Remove the bearing, flip it over, and re-insert it.

3. Inspect the Washers: The GTS500 uses a combination of Rulon and stainless steel washers. Wipe them dry. They are designed to run mostly dry or with a very microscopic film of specialized drag grease.

Step 3: Lubrication Points

Over-greasing is the most common mistake in reel repair. Apply grease only to the following:

• The Main Spindle: Apply a very thin layer of grease to the spindle shaft where the spool rotates.

• Clicker Dog: Lightly grease the small plastic or metal "clicker" tooth to ensure a smooth sound and reduce wear.

• Main Gear Teeth: Use a small brush to apply grease to the teeth of the drive gear.

Important: Do not get grease on the flat surfaces of the drag discs. This will cause the drag to "stutter" or lose its braking power.

Step 4: Reassembly

1. Seat the Bearing: Ensure the one-way bearing is seated fully in the housing.

2. Replace the Retainer: Tighten the retaining nut. Ensure it is snug but do not over-tighten, as this can strip the composite threads.

3. Test the Drag: Turn the drag knob to the lowest setting and spin the reel. Gradually increase the tension to ensure the resistance is smooth and linear.

4. Re-attach Spool: Align the spool with the spindle and press until you hear a firm click.

Troubleshooting Common Issues

Maintenance Tip

After every use in saltwater or brackish water, remove the cassette spool and rinse both the frame and the spool in lukewarm fresh water. Allow them to air dry completely before storage to prevent the "creeping" of salt crystals into the bearing housing.
