Lews Mach Crush Baitcast Reel 2nd Gen MCR1SHA

Comprehensive Repair and Maintenance Guide: Lew’s Mach Crush (2nd Gen)

Model: MCR1SHA

The 2nd Gen Mach Crush is a high-performance baitcaster recognizable by its vibrant orange accents and oversized "Winn Dri-Tac" handle knobs. It features a high-speed 7.5:1 gear ratio and a specialized dual-braking system. Maintaining this reel requires attention to both the centrifugal and magnetic components to keep its "crush" performance smooth.

Step 1: External Disassembly

1. Handle Removal: Unscrew the handle nut retainer screw, then use a 10mm wrench to remove the handle nut. Pull off the 95mm bowed handle. Note the Winn Dri-Tac knobs; if they are tacky or dirty, clean them only with mild soap and water—solvents will ruin the grip.

2. Accessing the Spool: Flip the locking lever on the palm-side plate and rotate to remove. Slide out the 32mm U-shape anodized aluminum spool.

3. Side Plate Removal: Remove the three screws from the gear side plate. Carefully lift the plate to avoid popping the spring-loaded thumb bar mechanism.

Step 2: The Multi-Setting Brake (MSB) System

The 2nd Gen Mach Crush uses a dual-braking system (Magnetic + Centrifugal). This is the most common area for debris buildup.

1. Centrifugal Pins: On the spool hub, you will find four centrifugal shoes. Ensure they "click" in and out freely. If they are stuck, the reel will be noisy during casts.

2. Magnetic Ring: The palm-side plate contains the magnetic dial components. Wipe the inner surface of the plate to remove any metallic dust.

3. Cleaning: Use a cotton swab with a tiny amount of alcohol to clean the brass friction ring inside the side plate. A dirty ring causes inconsistent braking and "surging" during a cast.

Step 3: Gear Train and Drag Service

The Mach Crush features high-strength solid brass gears for durability under high speed.

1. Gear Cleaning: Remove the main brass gear and the pinion gear. If the grease is dark or "milky," it has been contaminated with water. Soak the gears in solvent and scrub with a soft brush.

2. Carbon Fiber Drag: The Mach Crush boasts a 20 lb drag system.

   • Inspect the three carbon washers. If they appear glazed or shiny, the drag will "stutter."

   • Clean them with alcohol. For this specific model, a very light coat of universal drag grease is recommended to handle the heat of the 7.5:1 retrieval speed.

3. Pinion Yoke: Check the two springs on the pinion gear yoke. If the reel is "grinding" when you turn the handle after a cast, the yoke may not be fully engaging the pinion.

Step 4: Lubrication Points

• Spool Bearings: The Mach Crush relies on a 10-bearing system. For maximum distance, flush the spool bearings and add one drop of thin, high-speed oil.

• Main Gear: Apply synthetic grease to the brass teeth. Use enough to fill the gaps but avoid getting grease on the drive shaft or near the one-way clutch bearing.

• Level Wind: The Mach Crush has a wide aperture line guide. Apply a drop of oil to the worm shaft every 4–5 trips to ensure smooth line lay.

Step 5: Reassembly and Fine-Tuning

1. Yoke Placement: Ensure the pinion gear is seated with the "slotted" end facing the spool.

2. Closing the Case: Reinstall the gear side plate. Ensure the "Lube Port" screw on the bottom is tight.

3. Tension Setting: Reinstall the spool. Tighten the tension knob until the spool has no side-to-side play. On the Mach Crush, the tension knob features an audible click—use this to "fine-tune" based on lure weight.

Maintenance Checklist

Pro Tip: Because the 2nd Gen Mach Crush is often used for "power fishing" (spinnerbaits and chatterbaits), the vibration can loosen the handle nut over time. Always check the tightness of the retainer screw before a tournament or long trip.
