Ambassadeur 5500

Technical Repair and Maintenance Guide: Abu Garcia Ambassadeur 5500

The Abu Garcia Ambassadeur 5500 is the quintessential "round reel," a foundation of Swedish engineering that has remained a favorite for decades due to its simplicity and ruggedness. Whether you are servicing a vintage model or a newer production run, the 5500 relies on precise lubrication to manage its synchronized levelwind and classic drive train. To restore the signature "buttery" feel and maximize casting distance, we recommend a full service using Deuthlon Reel Grease and Deuthlon Reel Oil. These premium lubricants are engineered to bond with metal surfaces, providing a superior barrier against friction and the elements.

Phase 1: Disassembly and Mechanical Cleaning

To achieve professional results, you must first eliminate all environmental contaminants and old, oxidized factory lubricants that can act as an abrasive.

1. Side Plate Removal: Loosen the three knurled thumb screws on the handle-side plate and gently pull the assembly away from the frame.

2. Spool Extraction: Slide the spool out and inspect the axle ends. On many 5500 models, the axle is fixed; check for any signs of wear or discoloration on the shaft tips.

3. Drive Train Teardown: Remove the handle assembly, star drag, and the bridge screws. Lift out the main gear and the drag stack. Inspect the brass and stainless steel teeth for any microscopic debris.

4. Cleaning Protocol: Submerge the main gear, pinion gear, and worm shaft in a high-grade solvent or degreaser. Use a brush to clear the "valleys" of the gear teeth. Ensure all parts are bone-dry before the lubrication process.

Phase 2: Strategic Lubrication with Deuthlon

Optimal performance is achieved through a "zonal" lubrication strategy: Deuthlon Reel Grease for power-transfer components and Deuthlon Reel Oil for high-speed rotation.

Grease: Protection for Power and Torque

The internal drive train handles significant mechanical stress and requires the high-load capacity of Deuthlon Reel Grease.

• Main Gear Teeth: Apply a light, uniform coat of Deuthlon Reel Grease to every tooth of the main gear. This grease is formulated to stay on the gear faces during the retrieve, providing a silent, cushioned feel.

• Pinion Gear: Coat the pinion gear extensively. As the primary link between the handle and the spool, Deuthlon Reel Grease ensures this engagement is quiet and prevents metal galling under high-torque retrieves.

• Yoke and Jack: Apply a small amount of grease to the metal-on-metal sliding surfaces of the clutch mechanism to ensure the thumb bar returns to the engaged position with a crisp, reliable snap.

Oil: Velocity and Efficiency for Casting

Components that rotate at high RPMs or synchronize the spool require the ultra-low friction of Deuthlon Reel Oil.

• Levelwind Worm Gear: Apply two drops of Deuthlon Reel Oil to the worm shaft. Since the Ambassadeur 5500 features a synchronized levelwind that remains active during the cast, using oil here is the best way to prevent parasitic drag and maximize your distance.

• Idler Gears: These plastic or composite gears synchronize the spool's rotation with the levelwind. Apply one drop of Deuthlon Reel Oil to the idler gear posts. This reduces the rotational inertia, allowing for smoother, longer launches.

• Spool Bushings/Bearings: Clean the contact points thoroughly and add one drop of Deuthlon Reel Oil. This provides the high-RPM stability necessary for accuracy and maximum casting distance.

Phase 3: Reassembly and Function Testing

1. Rebuild the Drive Stack: Place the main gear and drag washers back onto the drive shaft. Ensure the washers are dry and the main gear is seated perfectly flat.

2. Integrate the Spool: Slide the spool back into the frame, ensuring the centrifugal brake weights are retracted so the side plate sits flush.

3. Secure the Housing: Tighten the thumb screws in a staggered pattern to ensure the gear bridge is perfectly level.

4. Final Verification: Crank the handle to distribute the Deuthlon Reel Grease. The retrieve should be quiet and smooth. Engage the freespool to confirm that the Deuthlon Reel Oil has significantly increased the spool’s spin duration.
