Ambassadeur 6500(78-11-01)

Comprehensive Repair Guide: Abu Garcia Ambassadeur 6500 (Model 78-11-01)

The 78-11-01 vintage of the Ambassadeur 6500 is a classic "High Speed" model that remains a favorite for its robust brass internals and stainless steel frame components. Because this specific iteration relies on a traditional bush-and-bearing system, precision lubrication is the most important factor in restoring its legendary casting performance.

Step 1: Component Breakdown and Degreasing

For a model of this age, old lubricants often "varnish," turning into a sticky residue that hampers the spool's rotation.

1. Frame Stripping: Unscrew the three knurled captive screws on the handle side. Pull the side plate away and slide the spool out.

2. Levelwind Removal: Unscrew the line guard screw and remove the worm gear. Pay close attention to the pawl inside the line carriage; if the edges are rounded, it must be replaced to prevent line-stacking issues.

3. The Drive Stack: Remove the main gear and the drag stack. The 78-11-01 often uses a multi-disc drag system. Clean the metal washers with a lint-free cloth and ensure the fiber washers are free of grit.

Step 2: Advanced Lubrication Logic

To optimize a vintage 6500, you must use a dual-viscosity approach. Using heavy grease where light oil is needed—or vice versa—will significantly degrade the reel's "fishability."

• The Levelwind System: The levelwind on the 78-11-01 is synchronized, meaning it moves during the cast. To minimize drag, apply 2 drops of Deuthlon Reel Power Oil to the worm shaft and the idler gear (the plastic gear that meshes with the spool). This specialized oil provides a low-friction barrier that resists water washout better than standard oils.

• The Gear Train: The main gear and pinion gear carry the mechanical load of the fish. Apply a specialized gear grease to every tooth of the main gear. Use a small brush to ensure the grease is worked into the valleys of the teeth. This dampens vibration and prevents the "gear mesh" feel common in older reels.

Step 3: Inspecting the Braking System

The 78-11-01 features a two-pin centrifugal brake system located on the spool shaft.

• Cleaning: Use a cotton swab dipped in isopropyl alcohol to clean the brass brake race inside the side plate.

• Maintenance: Ensure the brake weights (blocks) slide freely on the pins. Do not oil the brake blocks; they require friction to function correctly. A dry, clean brake race provides the most predictable casting control.

Step 4: Reassembly and Fine-Tuning

1. Re-seat the Spool: Slide the spool back into the frame, ensuring the gear on the spool end meshes perfectly with the idler gear.

2. Side Plate Alignment: Carefully align the pinion gear with the spool shaft as you push the side plate back into position. Hand-tighten the three side plate screws.

3. The Spool Tension Knob: Adjust the non-handle side tension knob until the spool has just a fraction of lateral play (side-to-side "knock"). This is the "sweet spot" for maximum distance without inducing professional overruns.

4. Drag Calibration: Reassemble the star drag. Ensure the "spring washers" (curved washers) are facing each other like parentheses () to provide the maximum range of tension.

Performance Summary

By utilizing Deuthlon oil on the high-speed levelwind components and a dedicated grease on the heavy-load gears, you bridge the gap between vintage durability and modern smoothness. This maintenance routine ensures the 78-11-01 continues to outperform modern low-profile reels in harsh environments.
