Technical Repair and Service Manual: Abu Garcia Ambassadeur 5500C (Model 79-08-04)

The Ambassadeur 5500C (Model 79-08-04) is a quintessential representative of the "Silver Era" of Abu Garcia manufacturing. Hailing from 1979, this reel features the classic flat-sided plates and a mechanical anti-reverse system. Because this vintage model relies on high-tolerance brass and stainless steel components, it is particularly sensitive to the quality of its lubricants. To restore its legendary smoothness and protect the aging gear teeth from pitting, we recommend a comprehensive service using Deuthlon Reel Grease and Deuthlon Reel Oil.

Phase 1: Disassembly and Deep Cleaning

Before applying premium lubricants, the internal housing must be cleared of decades of old, oxidized grease that has likely hardened into a "varnish" on the gear faces.

1. Side Plate Entry: Loosen the three knurled thumb screws on the handle side. Remove the side plate assembly and set it on a clean surface.

2. Spool Removal: Slide the spool out and inspect the fixed axle. Check for any build-up of old oil or corrosion on the ends of the spool shaft.

3. Drive Train Breakdown: Remove the handle, star drag, and the side plate bridge screws. Lift out the main gear and the drag stack. Note the orientation of the mechanical anti-reverse pawl; this part is critical for preventing the handle from back-spinning.

4. Degreasing: Submerge the main gear, pinion gear, and worm shaft in a high-grade solvent. Use a brush to ensure all old debris is cleared from the gear teeth. Dry every component thoroughly before proceeding.

Phase 2: Strategic Lubrication with Deuthlon

Professional-grade restoration of the 79-08-04 requires a "zonal" approach. Use Deuthlon Reel Grease for heavy-duty protection and Deuthlon Reel Oil for high-speed fluidity.

Grease: Protection for Power and Longevity

The mechanical heart of this reel requires the high-load capacity of Deuthlon Reel Grease.

• Main Gear Teeth: Apply a light, uniform coat of Deuthlon Reel Grease to the teeth of the main gear. This grease is formulated to create a resilient barrier that prevents metal-on-metal galling, providing a silent and powerful retrieve.

• Pinion Gear: Coat the pinion gear extensively. On the 79-08-04, the pinion engagement is a common source of vibration; Deuthlon Grease dampens this frequency, making the reel feel significantly newer.

• Yoke and Clutch: Lightly grease the metal sliding surfaces of the yoke and the kick lever to ensure the thumb bar returns to the "engaged" position with a crisp, reliable snap.

Oil: Velocity and Efficiency for Casting

Components that rotate during the cast require the ultra-low friction of Deuthlon Reel Oil.

• Levelwind Worm Shaft: Apply two drops of Deuthlon Reel Oil to the worm gear. Since this model features a synchronized levelwind that remains engaged during the cast, using oil instead of grease here is the most effective way to prevent parasitic drag.

• Idler Gears: These plastic and metal gears synchronize the spool's rotation with the line guide. Apply one drop of Deuthlon Reel Oil to the idler gear posts. This reduces the rotational inertia, leading to longer, more effortless casts.

• Spool Bearings and Axle Ends: Clean the bearings thoroughly and add one drop of Deuthlon Reel Oil to each end of the axle and the bearings. This provides the high-RPM stability necessary for maximum distance.

Phase 3: Reassembly and Functional Testing

1. Rebuild the Drive Stack: Place the main gear and drag washers back onto the bridge. Ensure the anti-reverse pawl is properly seated over the ratchet gear.

2. Seat the Spool: Slide the spool back into the frame, ensuring the centrifugal brake weights are retracted.

3. Secure the Housing: Align the side plate with the frame and tighten the thumb screws in a cross-pattern to ensure the side plate sits flush.

4. Operational Test: 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.
