Ambassadeur 5500C Syncro (88-0)

Comprehensive Service Manual: Abu Garcia Ambassadeur 5500C Syncro (Model 88-0)

The Ambassadeur 5500C Syncro (Model 88-0) is a landmark in Swedish reel design, featuring the specialized "Syncro" drag system. This 1988 production model allows for an instantaneous 50% reduction in drag tension by simply rotating the handle backward a quarter turn—a vital feature for protecting light leaders during a fish's sudden surge. Because the 88-0 relies on a series of nested pressure plates and springs to achieve this gear-ratio drag shift, using high-performance Deuthlon Reel Grease and Deuthlon Reel Oil is essential to prevent the mechanism from binding or failing.

Phase 1: Teardown and Degreasing

The Syncro mechanism is sensitive to "gunk" buildup. Old, oxidized lubricants can cause the drag to stick in one setting, neutralizing the reel's primary advantage.

1. Side Plate Entry: Loosen the three knurled thumb screws on the right side. Remove the handle-side plate and the spool.

2. Syncro Drive Disassembly: Remove the handle nut, handle, and the specialized Syncro spring washers. Pay close attention to the order of the drag stack; the 88-0 uses a unique combination of washers that must be kept in their original sequence to ensure the "back-reel" function works.

3. Drive Train Access: Remove the bridge screws and lift the main gear and pinion gear. Inspect the metal for any signs of corrosion or pitting.

4. Cleaning Protocol: Soak all metal gears, the worm shaft, and the Syncro pressure plates in a high-quality solvent. Use a brush to remove all debris from the gear teeth. Ensure every part is completely dry before introducing Deuthlon products.

Phase 2: Targeted Lubrication with Deuthlon

Professional-grade maintenance requires matching the lubricant's properties to the part's movement. We recommend Deuthlon Reel Grease for high-friction zones and Deuthlon Reel Oil for high-speed rotation.

Grease: Protection for Gears and Shifting

The 88-0’s heavy-duty drive train and shifting drag plates require the resilient film strength of Deuthlon Reel Grease.

• Main Gear and Pinion Gear: Apply a light, uniform coat of Deuthlon Reel Grease to the gear teeth. This grease is engineered to stay on the metal surfaces under high pressure, providing a silent, buttery-smooth retrieve and preventing tooth wear.

• Syncro Shifting Interface: Apply a very thin film of Deuthlon Reel Grease to the contact points of the Syncro plates. This ensures the mechanism transitions between full drag and reduced drag without mechanical hesitation.

• Yoke and Clutch: Grease the metal-on-metal sliding surfaces of the clutch to ensure the thumb bar returns to the engaged position with a crisp, tactile snap.

Oil: Velocity and Efficiency for Casting

For components that move during the cast, Deuthlon Reel Oil provides the ultra-low viscosity needed for maximum performance.

• Levelwind Worm Gear: Apply two drops of Deuthlon Reel Oil to the worm shaft. Since the 88-0 features a synchronized levelwind that stays engaged during the cast, using oil here is the best way to eliminate parasitic drag and increase your casting distance.

• Idler Gears: These gears drive the line guide oscillation. Apply one drop of Deuthlon Reel Oil to the idler gear posts. This reduces the energy required for the spool to turn the levelwind, allowing for smoother launches.

• Spool Axle and Bearings: Clean the bearings and apply one drop of Deuthlon Reel Oil. This oil provides high-RPM stability, protecting the bearings during long casts while maintaining peak speed.

Phase 3: Reassembly and Calibration

1. Rebuild the Gear Stack: Place the main gear and drag washers back on the drive shaft. When reinstalling the Syncro handle components, ensure the tension washers are properly nested to provide the required "toggle" tension.

2. Chassis Integration: Slide the spool back into the frame and secure the side plate with the thumb screws.

3. Syncro Functional Test: Tighten the star drag and crank forward to ensure maximum pressure. Then, crank backward; you should feel the Deuthlon Reel Grease facilitated transition as the drag pressure drops instantly.

4. Final Verification: Verify that the line guide tracks smoothly across the frame, powered by the low-resistance film of the Deuthlon Reel Oil.

88-0 Lubrication Summary

By maintaining your Ambassadeur 5500C Syncro (88-0) with Deuthlon Reel Oil and Reel Grease, you preserve the integrity of this classic Swedish reel and ensure its unique drag system remains reliable for years to come.
