Wacker Neuson 5002001045 Internal Retaining Ring 40Mmx1.7Mm

The Wacker Neuson Internal Retaining Ring 40Mmx1.7Mm is a genuine OEM component designed for BTS series power cutters, gasoline and diesel power units for internal vibrators, and double drum vibratory rollers. As a direct factory part, the is manufactured to Wacker Neuson's exact dimensional tolerances, ensuring a drop-in fit with no guesswork on sizing or seating. This ring is compatible across a broad range of equipment including the BTS 930, BTS 935, BTS 1030, BTS 1035, and BTS 1140 L3 power cutters, as well as the A3000, B3000, B5000, A5000, X3000, and D4000 power units. When you're sourcing a retaining ring that has to seat correctly and hold reliably under load, genuine OEM is the straightforward choice.

Key Features

• OEM-Exact Snap Groove Engagement — Manufactured to Wacker Neuson's precise 40mm bore and 1.7mm groove specification, so the ring seats fully and holds its retention load without distortion or slippage.
• Direct-Fit Replacement — Installs directly into the existing groove with standard snap-ring pliers — no resizing, filing, or shimming required to achieve proper seating depth.
• Broad Model Coverage — Fits BTS 930, 935, 1030, 1035, and 1140 L3 power cutters, plus the A3000, B3000, B5000, A5000, X3000 gasoline power units, D4000 diesel power unit, and RD880V double drum vibratory roller.
• Axial Load Security — A correctly seated retaining ring prevents shaft and bearing axial migration under vibration and torque loads — a failed or undersized ring allows component walk that causes accelerated wear and mechanical failure.
• Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying the same part number 5002001045 used by authorized service centers, so you can be confident you're receiving the correct part for the application.

An internal retaining ring — also called a snap ring — fits into a machined groove on the inside of a bore to retain a shaft, bearing, or rotating component in its axial position. It works by creating a positive mechanical stop that prevents the retained component from moving along the shaft under the forces generated during operation. When a retaining ring becomes worn, distorted, or dislodged, the component it secures can shift out of position, leading to uneven bearing loads, accelerated wear on surrounding parts, and potential mechanical failure of the assembly. Replacing a damaged or missing retaining ring promptly is one of the simplest and most cost-effective steps in keeping a drivetrain or power unit assembly operating as intended.
