Ambassadeur 6500C Syncro(88-1)

Mechanical Restoration Guide: Abu Garcia Ambassadeur 6500C Syncro (Model 88-1)

The Ambassadeur 6500C Syncro (Foot Number 88-1) is a masterpiece of Swedish engineering from the late 1980s. This model introduced the "Syncro" drag system, a sophisticated mechanical override that allows anglers to instantly reduce drag tension by 50% by rotating the handle backward. Because the 88-1 relies on a complex hub assembly and a synchronized levelwind system, maintaining the delicate balance between high-speed casting and technical drag management is vital.

Phase 1: Disassembly and Syncro Mechanism Inspection

The 88-1 features more internal components than a standard 6500, requiring a methodical teardown to ensure the drag-shift feature remains functional.

1. Remove the Handle Assembly: Unscrew the handle nut and remove the handle. Carefully lift off the Syncro-specific star drag. Underneath, you will find the Syncro pressure plate and a series of spring washers—take note of their orientation.

2. Access the Drive Bridge: Loosen the three bridge screws on the right side plate. Lift the plate to reveal the main gear and the specialized Syncro drag hub. Inspect the hub for any burrs or salt deposits that could impede the "back-wind" release.

3. Spool and Bearing Removal: Slide the spool out. As a "C" series reel, it houses stainless steel ball bearings. Use a fine pick to remove the retaining clips from the side plate housings and extract the bearings.

4. Levelwind Teardown: Unscrew the pawl cap and remove the pawl. Slide the worm gear and the protective shroud out of the frame.

Phase 2: Deep Cleaning and Degreasing

Old, "gummed up" grease is the primary cause of failure in the Syncro system, often causing the drag to stick in one setting.

• The Syncro Hub: Submerge the main gear and the Syncro hub components in a high-grade degreaser. Use a soft brush to scrub the internal ramp of the hub where the drag-shifting occurs.

• Bearing Refresh: Soak the ball bearings in isopropyl alcohol. Spin them while submerged to flush out decades of micro-grit. Once dry, they should spin silently.

• The Frame: Wipe the interior of the frame clean. Pay close attention to the plastic idler gear; ensure the teeth are free of debris, as this gear synchronizes the levelwind with the spool's rotation.

Phase 3: Strategic Lubrication Protocol

For the 88-1 to cast effectively while maintaining a smooth retrieve, a dual-viscosity lubrication strategy is mandatory.

Levelwind and Idler Gears (High-Speed Oscillation)

The levelwind on the 6500C Syncro is synchronized, meaning the line guide moves during the cast. This creates a high amount of mechanical drag. To counteract this, apply Deuthlon Reel Power Oil to the worm shaft and the teeth of the idler gears. This high-speed synthetic oil provides a "slick" barrier that doesn't thicken, allowing the line guide to oscillate with almost zero resistance and significantly increasing your casting distance.

Main and Pinion Gears (Load-Bearing Power)

The drive train and Syncro hub handle the mechanical pressure of the retrieve and the drag system. Apply a thin, even coat of high-viscosity gear grease to the teeth of the main gear and the pinion gear. This grease acts as a cushion, dampening gear noise and preventing metal-on-metal wear during heavy fights.

Phase 4: Reassembly and Mechanical Calibration

1. Rebuild the Gear Stack: Place the pinion gear into the yoke and seat the main gear on the drive shaft. Reassemble the Syncro hub, ensuring the drag washers are clean and dry.

2. Bearing Lubrication: Place one drop of Deuthlon oil into each cleaned ball bearing before reseating them. This ensures the spool reaches maximum RPM during the cast.

3. Levelwind Integration: Reinstall the worm gear and line carriage. Apply a drop of oil to the pawl before tightening the pawl cap.

4. Closing the Reel: Realign the side plates and tighten the screws. Reinstall the Syncro star drag and handle.

Technical Fine-Tuning

Adjust the mechanical tension knob until the side-to-side play of the spool is just barely eliminated. Test the Syncro feature by tightening the drag, then cranking the handle backward; you should feel a distinct "click" as the tension drops. With Deuthlon oil on the high-speed components and fresh grease on the gears, your Ambassadeur 6500C Syncro 88-1 is restored to its peak professional performance.
