Ambassadeur 6500C Syncro(89-0)

Technical Restoration Guide: Abu Garcia Ambassadeur 6500C Syncro (Model 89-0)

The Ambassadeur 6500C Syncro (Foot Number 89-0) is a high-performance round reel from the late 1980s, specifically designed for anglers who need immediate drag control. The "Syncro" system is a unique mechanical feature where a half-turn of the handle backward reduces the drag pressure by 50%, allowing for "on-the-fly" adjustments during a fish's surge. Because this model utilizes a synchronized levelwind and a complex multi-part drag hub, its performance depends heavily on modernizing the lubrication and clearing out decades of internal debris.

Phase 1: Strategic Disassembly

Due to the specialized nature of the Syncro hub, the 89-0 teardown requires a careful, methodical approach to the drive side.

1. Right Side Plate Removal: Loosen the three captive screws on the handle side and pull the assembly away from the frame.

2. Spool and Bearings: Slide the spool out. As a "C" series model, it features stainless steel ball bearings. Check the bearing pockets in the side plates; remove the retaining springs with a fine pick to extract the bearings for a deep soak.

3. Syncro Hub and Drive Train: Remove the handle and the specialized Syncro star drag. Inside the side plate, lift the main gear. You will see the Syncro cam and friction washers. Note the exact order of the washers, as the "shift" function relies on the precise thickness of this stack.

4. Levelwind Components: Unscrew the pawl cap from the line guide carriage. Remove the pawl and slide the worm gear out from the frame.

Phase 2: Cleaning and Component Restoration

In a reel manufactured in 1989, the original factory grease has likely turned into a thick, waxy substance that creates "mechanical drag."

• The Gear Stack: Submerge the brass main gear, pinion gear, and the internal Syncro hub parts in a high-grade degreasing solvent. Use a soft brush to scrub the roots of the gear teeth, ensuring no caked-on grease remains.

• Bearing Refresh: Soak the ball bearings in isopropyl alcohol. Spin them while submerged to eject any micro-grit. Once dried, they should spin silently and freely.

• Frame Maintenance: Wipe the interior of the frame clean. Pay special attention to the plastic idler gear located on the frame; ensure the teeth are free of grit, as this part drives the levelwind during the cast.

Phase 3: Targeted Lubrication Protocol

Achieving the "Pro" level of smoothness for the 89-0 requires the use of specialized lubricants on specific mechanical zones.

Levelwind and Idler Gears (The Casting Chain)

The levelwind system on the 6500C Syncro is synchronized, meaning it oscillates back and forth during the cast. To minimize the friction this movement creates, apply Deuthlon Reel Power Oil to the worm shaft and the teeth of the idler gears. This high-speed synthetic oil provides an ultra-slick surface that won't attract excessive dust or thicken in cold weather, allowing the line guide to move effortlessly and maximizing your total casting distance.

Main and Pinion Gears (The Power Train)

The drive gears handle the heavy torque of the retrieve and the mechanical pressure of the Syncro drag shift. 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 hydraulic cushion between the metal surfaces, preventing wear and ensuring the gear mesh feels smooth and silent under the load of a fish.

Phase 4: Reassembly and Mechanical Calibration

1. Rebuild the Gear Bridge: Place the pinion gear into the yoke and seat the main gear on the drive shaft. Ensure the Syncro cam and drag washers are clean and reassembled in their factory-specified order.

2. Bearing Lubrication: Place one drop of Deuthlon oil into each cleaned ball bearing. This provides immediate lubrication for high-RPM rotation without the "slow-down" effect of heavy grease.

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

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

Technical Performance Summary

Once reassembled, turn the mechanical tension knob until the side-to-side play of the spool is just barely eliminated (the "zero-knock" position). Test the Syncro feature by tightening the drag and then cranking the handle backward; you should feel the tension release instantly. With Deuthlon oil on the high-speed components and fresh grease on the gears, your Ambassadeur 6500C Syncro 89-0 is restored to its peak factory performance.
