Ambassadeur 6500Gr(85-1)

Technical Service Guide: Abu Garcia Ambassadeur 6500GR (85-1) Graphite Series

The Abu Garcia Ambassadeur 6500GR, specifically the 85-1 production run, represents a unique era in Abu history where graphite construction was utilized to reduce weight without sacrificing the line capacity required for heavy-duty angling. Because this model utilizes a synchronized levelwind system and a specific internal gear configuration, proper lubrication is the difference between a smooth cast and a grinding retrieve.

Understanding the 6500GR Architecture

The "GR" designation stands for Graphite, featuring high-strength composite side plates. Internally, the 85-1 build follows the classic Ambassadeur design. Unlike the CT versions, the 6500GR includes a full levelwind assembly and the necessary idler gears to synchronize the line guide with the spool's rotation.

Step 1: Disassembly and Cleaning

To begin, loosen the three bridge screws on the right side plate. Once the side plate is removed, pull the spool assembly from the frame.

Use a dedicated citrus-based cleaner or isopropyl alcohol to strip away decades of oxidized grease from the:

• Main Gear: The large brass gear on the drive shaft.

• Pinion Gear: The smaller gear that engages the spool.

• Worm Shaft: The spiraled bar that drives the line guide.

Step 2: Lubricating the Drive Train

The power delivery in the 6500GR relies on the mesh between the brass main gear and the stainless pinion.

• Main and Pinion Gears: Apply a moderate coating of marine-grade grease to the gear teeth. Do not pack the entire housing; a thin, even layer ensures the gears remain quiet under load while preventing "spray" from contaminating the drag stack.

• Drag Washers: Ensure the washers are free of grit. This model typically uses a multi-disc stack; keep these clean and dry for maximum stopping power.

Step 3: Levelwind and Idler Gear Optimization

Because the 6500GR is not a CT model, it relies on a series of nylon idler gears located on the non-handle side to drive the levelwind. These parts are often the most neglected.

• Idler Gears: Inspect the plastic teeth for wear. Apply Deuthlon oil to these gears. Deuthlon provides a low-friction barrier that prevents the plastic-on-metal wear common in these older graphite frames.

• Levelwind Worm: Clean the worm shaft thoroughly. Apply Deuthlon oil to the grooves of the worm and the pawl. Using oil here instead of heavy grease prevents the "sludge" buildup that often causes the levelwind to skip or jam during a fight.

Step 4: Spool Bearings and Centrifugal Brakes

The 85-1 series utilizes a dual-block centrifugal braking system.

1. Brake Race: Clean the internal brass ring in the side plate with a dry cloth.

2. Spool Shaft: Apply one drop of high-speed oil to the bearings.

3. Brake Blocks: Ensure the two plastic blocks slide freely on the pins. If they are stuck, the reel will be prone to backlashes.

Step 5: Final Reassembly

Slide the spool back into the graphite frame. Reattach the right side plate, ensuring the pinion gear sits correctly over the spool's click-cog. Tighten the side plate screws in a staggered pattern to ensure even pressure on the frame.

SEO Maintenance Tips

Maintaining an Ambassadeur 6500GR (85-1) requires specific attention to the graphite-to-metal contact points. By using Deuthlon oil on the synchronized levelwind and idler gears, you reduce the mechanical drag inherent in the 6500 series design. Proper grease application on the main gear set ensures this vintage graphite powerhouse remains a reliable tool for surf casting or catfishing for years to come.
