The Wacker Neuson Snap Ring is a genuine OEM snap ring designed for the APT8S and APT8T pump series. Sourced directly from Wacker Neuson, this is the same snap ring installed at the factory, ensuring an exact match to the original component in your machine. It is confirmed to fit across the full APT8S and APT8T lineup, including surge brake, electric brake, and cold weather variants. When it comes to a small but critical retaining component like this, using the correct OEM part ensures proper seating, secure retention, and long-term integrity of the surrounding assembly.
Key Features
- Genuine OEM Retention Spec — Manufactured to Wacker Neuson's exact dimensional tolerances, ensuring the snap ring seats and locks correctly in its groove without deformation or play.
- Drop-In Replacement — Matches the original groove dimensions and ring diameter for straightforward installation with standard snap ring pliers — no fitting or adjustment needed.
- Broad APT8 Series Coverage — Compatible with APT8S Pump with Skid, APT8T Pump with Surge Brake, APT8T Pump with Electric Brake, and all corresponding Cold Weather variants.
- Secure Component Retention — A properly seated snap ring keeps shafts, pins, and bearings locked in position under load; a worn or missing ring allows axial movement that accelerates wear on adjacent components.
- OEM Part Number Verified — Cross-reference part number 5200021742 against your parts diagram to confirm fitment before ordering.
A snap ring is a small, spring-steel retaining ring that clips into a machined groove on a shaft or inside a bore to prevent axial movement of components such as bearings, pins, or gears. In a pump assembly like the APT8S and APT8T, it holds critical internal parts in their correct position under the repetitive load and vibration that pump operation generates. When a snap ring becomes worn, distorted, or missing entirely, the components it secures can shift out of alignment, leading to accelerated wear, internal damage, and potential pump failure.
