Lews BB1NIMP

Repair & Maintenance Guide: Lew’s Speed Spool (Vintage BB1NIMP)

The Lew’s BB1NIMP is a legendary artifact from the "Shimano-era" of Speed Spools. This specific model is a favorite among vintage collectors and cranking enthusiasts. To understand the reel, you have to decode the suffix: N (Narrow Spool), I (I-shape handle knobs), M (Multi-stop anti-reverse), and P (Power/Standard gear ratio).

Unlike modern "Zero-Reverse" reels, the BB1NIMP features a mechanical multi-stop system that provides that classic "clicking" sound during the retrieve. Because this reel was built with a one-piece die-cast aluminum frame and solid brass internals, it is nearly indestructible if maintained correctly.

Tools and Supplies Needed

• Tools: 10mm nut driver, a flat-head and Phillips-head precision screwdriver, and a pair of tweezers.

• Cleaning: 90% Isopropyl alcohol and a stiff toothbrush.

• Lubricants: High-quality synthetic reel grease (for gears) and a light machine oil (for bearings).

Step 1: Exterior Disassembly (Right-Handed)

1. Handle Removal: Remove the screw from the handle nut retainer. Use your 10mm driver to remove the handle nut (Counter-Clockwise to loosen). Pull off the handle and the star drag.

2. Star Drag Stack: Keep track of the Belleville Washers (the two bowed spring washers). For the drag to function with its full range of pressure, they must be reinstalled in an "opposing" orientation ().

3. Side Plate Access: On the vintage BB1 series, the palm-side plate is secured by three screws. Remove these and pull the plate away.

Step 2: The Narrow Spool and Centrifugal Brakes

1. The Spool: Carefully extract the Narrow (N) spool. Because the spool is thinner, the shaft is long and requires a straight pull to avoid bending.

2. Brake System: The BB1NIMP utilizes a simple 2-pin centrifugal brake system.

   • Inspection: Check the two plastic collars (weights) on the spool. If they are cracked or missing, the reel will backlash regardless of your thumb pressure.

   • Maintenance: Wipe the brass friction ring inside the side plate with alcohol. If the reel "screams" during a cast, apply a microscopic film of oil to this ring to dampen the vibration.

Step 3: Accessing the "Multi-Stop" Gear Box

1. Opening the Gear Side: Remove the three housing screws and lift the side plate.

2. The Main Gear: You will find a Heavy-Duty Solid Brass Main Gear.

   • Deep Cleaning: Over decades, the original grease often turns into a hard, waxy crust. Scrub the gear teeth with a toothbrush and alcohol until the brass shines.

   • Drag Washers: The BB1NIMP typically uses a multi-disc drag. These vintage washers are best run completely dry. If they are soaked in oil, the drag will "stutter" under load.

3. The Multi-Stop Dog (Key Feature): Look for the mechanical anti-reverse pawl (the "dog") at the base of the drive shaft.

   • The Rule: Apply one drop of oil to the pawl. Never grease this part. Grease will cause the pawl to stick, preventing it from grabbing the ratchet teeth, which results in the handle spinning backward when you try to set the hook.

Step 4: Lubrication and Reassembly

1. Main Gears: Apply a moderate coat of synthetic grease to the teeth of the main gear and pinion gear. You do not need to pack the housing; just ensure the teeth are coated.

2. Bearings: This reel features high-quality vintage ball bearings. Flush them with alcohol, dry them, and apply one drop of thin oil. If they are still noisy, they are likely pitted and should be replaced with standard 3x10x4mm bearings.

3. Worm Gear (Level Wind): This area is a magnet for grit. Clean it thoroughly and apply a light coat of grease. On the Narrow (N) model, ensure the Line Guide Pawl (the tooth inside the guide) is sharp. If it is rounded, the line will stack unevenly on the spool.

BB1NIMP Technical Summary

Troubleshooting Common Issues

• Handle "Back-Slap": If the handle moves back significantly before stopping, the anti-reverse dog is likely gummed up with old grease. Flush it with alcohol and apply a single drop of oil.

• Crunchy Retrieve: This usually indicates salt or sand in the brass main gear. A full degreasing and re-greasing is the only solution.

• The "I-Shape" Knobs: If the knobs are sticky or won't spin, apply a drop of oil to the base of the knob. If they are the original rubber/plastic blend, avoid using harsh solvents like acetone, which can melt the vintage material.

Final Note: The BB1NIMP is a "winching" reel. It is not designed for high-speed retrieval, but for pulling deep-diving crankbaits. If you maintain the brass gears and keep the multi-stop dog clean, this reel will likely outlast most modern graphite alternatives.
