Original DeWalt Driver Assembly N606148  — direct replacement for the 20 V MAX XR 16‑ga straight finish nailers DCN662B and DCN662D1. This is the original DeWalt driver assembly specified for the DCN662 series, so you can restore reliable driving action and consistent nail seating when the nailer’s driver or piston assembly is worn or damaged.

What you get: the complete driver assembly (housing and driver/piston interface) ready to accept the driver blade; it’s intended to be used with DeWalt driver blade N517610 (driver blade dimensions approximately 152 mm × 10 mm × 2.5 mm). Ideal when the tool is jamming, misfiring, or the driver blade is bent — swapping in this genuine DeWalt driver assembly brings the nailer back to spec.

This part is listed among DeWalt parts for the DCN662 models and matches the factory configuration, so it fits where the original driver assembly did.
