Ambassadeur 6500C 23 00 Rainbow

Technical Repair Guide: Abu Garcia Ambassadeur 6500C Rainbow (Model 23 00)

The Ambassadeur 6500C Rainbow (Foot Number 23 00) is a visually striking, high-performance variant known for its iridescent finish and "C" designation ball-bearing drive. This specific 23 00 production run relies on a synchronized levelwind system, where the line guide tracks in unison with the spool during the cast. Maintaining this mechanical harmony requires a precision-heavy approach to cleaning and a dual-lubricant strategy to ensure the "Rainbow" remains as functional as it is aesthetic.

Phase 1: Precision Teardown and Gear Inspection

To preserve the iridescent coating of the Rainbow model, ensure your tools are clean and your workspace is padded.

1. Removing the Power Side Plate: Back off the three knurled thumb screws on the handle side. Pull the plate assembly away to reveal the spool and the drive bridge.

2. Spool and Bearing Removal: Slide the spool out. In the 23 00 model, the stainless steel ball bearings are typically located in the side plate housings or on the spool shaft. Use a fine pick to remove the wire retaining clips and extract the bearings.

3. Drive Train Access: Remove the handle nut, handle, and star drag. Lift the bridge to expose the brass main gear and the carbon drag stack. Check the pinion gear teeth for any signs of "peeling" or wear.

4. Levelwind Breakdown: Unscrew the pawl cap and remove the pawl. Slide the worm gear and the protective line guide tube out of the frame.

Phase 2: Ultrasonic Cleaning and Degreasing

Old, contaminated lubricants are the primary cause of "backlash" and gear noise in vintage-style Ambassadeurs.

• Hard Parts: Submerge the brass main gear, stainless steel pinion, and worm shaft in a degreasing solvent. Use a soft brush to remove oxidized grease trapped in the gear teeth.

• Bearing Service: Soak the ball bearings in isopropyl alcohol. Spin them while submerged to ensure all internal grit is flushed out. Dry them thoroughly before lubrication.

• Frame Care: Wipe down the interior of the iridescent frame. Use a cotton swab to clean the teeth of the plastic idler gear, which transfers power from the spool to the levelwind.

Phase 3: The Advanced Lubrication Protocol

For a reel that features a synchronized levelwind, the choice of lubricant on the oscillation system is the difference between a mediocre cast and a professional-grade one.

High-Speed Oscillation (Levelwind and Idler Gears)

The levelwind system is the most significant source of drag during the casting cycle. To counteract this, apply Deuthlon Reel Power Oil to the worm shaft and the teeth of the idler gears. This specialized oil provides a high-speed, low-friction barrier that stays active even under extreme RPMs, allowing the line guide to oscillate effortlessly across the spool without "choking" the cast.

Load-Bearing Power (Main and Pinion Gears)

The drive train requires a lubricant that can withstand the pressure of a heavy retrieve. Apply a specialized gear grease to the teeth of the main gear. Use a small brush to create a thin, even coat; this creates a "viscous cushion" that prevents metal-on-metal grinding and ensures the gear mesh feels smooth and silent under the weight of a fish.

Phase 4: Reassembly and Mechanical Synchronization

1. Rebuild the Drive Bridge: Place the pinion gear into the yoke and seat the main gear on the drive shaft. Ensure the drag washers are clean and reassembled in their factory sequence.

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

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

4. Closing the Reel: Realign the Rainbow side plates with the frame. Tighten the thumb screws in a cross-pattern to ensure the spool remains perfectly centered.

Final Calibration

Once reassembled, turn the mechanical tension knob until the spool has zero lateral play (side-to-side "knock"). If the reel feels sluggish, it is likely due to over-greasing the drive gears. With Deuthlon oil on the levelwind and premium grease on the gears, your 6500C 23 00 Rainbow should cast silently and retrieve with a solid, buttery feel that matches its premium aesthetic.
