Ambassadeur 4600 Plus (84-1)

Maintenance and Repair Guide: Abu Garcia Ambassadeur 4600 Plus (84-1)

The Ambassadeur 4600 Plus (84-1) is a significant "Made in Sweden" model from the mid-1980s. The "Plus" series was marketed as a high-performance upgrade, often featuring a striking black or dark grey finish and a high-speed 5.3:1 gear ratio. This revision utilizes a 2-bearing system and a synchronized levelwind.

As a 40-year-old vintage reel, the 4600 Plus often suffers from a "stiff" thumb-bar or a noisy retrieve due to dried-out factory lubricants. To restore its signature Swedish precision and protect the classic brass internals, this guide utilizes Deuthlon Reel Grease and Deuthlon Reel Oil.

Phase 1: Exterior Disassembly

1. Handle and Star Drag: Remove the screw from the handle nut locking cap. Use a 10mm wrench to remove the handle nut. Pull off the handle, the tension washer, and the star drag wheel.

2. Spring Washers: Note the orientation of the two Belleville spring washers beneath the star drag. They must be reinstalled in an "opposing" orientation ( ) to provide a smooth, progressive drag range.

3. Side Plate Access: Loosen the three knurled thumb screws on the right side plate. Pull the side plate away from the frame and slide the spool out.

   Note: The 84-1 model typically uses two small white or black plastic centrifugal brake blocks on the spool spindle. Ensure these do not fall off during disassembly.

Phase 2: Drive Train and Gear Maintenance

The 4600 Plus features high-grade brass main gears. Because this is a "Plus" model, the tolerances are tight, and any grit or old, hardened grease will be felt immediately through the handle.

1. Cleaning the Internals: Remove the internal screws securing the handle-side plate to the frame pillars. Lift the plate to reveal the main gear and pinion assembly. Use a degreaser to strip away all old, gummy lubricant.

2. Grease Application: Apply a light, even coat of Deuthlon Reel Grease to the teeth of the Main Gear and the Pinion Gear. This grease is specifically designed to adhere to metal under load, providing a silent mesh and preventing the "notchy" feel common in vintage brass.

3. Clutch Mechanism: Apply a small amount of grease to the pinion yoke and the contact points of the kick lever. This ensures the thumb-bar engagement remains crisp and reliable.

Phase 3: Levelwind and Idler Gear System

Because the levelwind on the 4600 Plus is synchronized, the line guide oscillates during the cast. Any mechanical drag here acts as a parasitic brake on your spool.

1. Worm Shaft Service: Unscrew the pawl cap on the bottom of the line guide and remove the metal pawl. Slide the worm shaft out and clean the "double-helix" grooves of any trapped grit.

2. Idler Gear Inspection: Locate the white nylon idler gear (often called the cog wheel) on the frame. Ensure the teeth are clean and it rotates freely on its post.

3. Oil Application: Apply Deuthlon Reel Oil to the Levelwind Worm Shaft and the Idler Gear. Do not use grease. The light viscosity of Deuthlon oil allows the levelwind to move with almost zero resistance, which is essential for maximizing casting distance in this classic frame.

Phase 4: Bearings and Spindle

1. Bearing Service: Locate the two stainless steel spool bearings—one in the side plate tension knob and one in the opposite side plate.

2. Lubrication: Clean the bearings thoroughly with a solvent. Apply exactly one drop of Deuthlon Reel Oil to each bearing race. This maintains the ultra-low start-up inertia required for casting while providing a protective film for the stainless steel races.

3. Anti-Reverse Pawl: The 84-1 model utilizes a mechanical anti-reverse "dog." Clean the pawl and apply a tiny drop of oil to its pivot point. Do not grease this part, as it can cause the pawl to become "lazy" and fail to catch the ratchet gear.

Phase 5: Reassembly and Testing

1. Set the Gear Box: Reseat the pinion gear into the yoke and slide the main gear/drag stack back onto the drive shaft.

2. Close the Frame: Align the side plate with the frame and tighten the thumb screws.

3. Insert Spool: Slide the spool back into the frame, ensuring the spindle seats properly in the pinion gear.

4. Final Hardware: Reinstall the star drag, spring washers, handle, and 10mm nut. Secure the locking cap with the screw.

Performance Verification

Depress the thumb bar to verify the reel enters free-spool mode effortlessly. Spin the spool by hand; the line guide should track back and forth smoothly across the frame. Turn the handle to engage the gears. The combination of Deuthlon Reel Grease on the primary gears and Deuthlon Reel Oil on the levelwind and idler gears ensures your Ambassadeur 4600 Plus (84-1) performs with its original Swedish excellence.
