The Wacker Neuson Collar Ring is a genuine OEM component designed for the APT4S and APT4T pump series, including standard, electric brake, surge brake, and cold weather variants. Sourced directly from Wacker Neuson, this part meets the exact dimensional and material specifications of the original, ensuring a correct, trouble-free installation. It fits across the full APT4S and APT4T lineup, covering both standard and cold weather configurations.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the precise bore and profile tolerances required for proper collar seating in Wacker Neuson pump assemblies.
- Drop-In Replacement — Matches the original mounting interface exactly, allowing straightforward installation without reworking surrounding components.
- Broad APT Series Coverage — Compatible with APT4S Pump with Skid, APT4T Pump with Surge Brake, APT4T Pump with Electric Brake, and all corresponding cold weather variants.
- Maintains Pump Integrity — A correctly fitted collar ring keeps rotating or sliding components properly aligned and retained; a worn or failed ring can lead to misalignment, accelerated wear on adjacent parts, and pump performance loss.
- Authorized Wacker Neuson Part — Supplied through the official Wacker Neuson parts network, ensuring traceability and confidence in part number 5200020153 before it goes into service.
A collar ring is a precision retaining component that locates and secures a shaft, sleeve, or fitting within an assembly, preventing axial movement and keeping mating parts correctly positioned during operation. In pump applications, it plays a key role in maintaining the mechanical alignment that allows the pump to deliver consistent flow and pressure. When a collar ring wears, cracks, or loses its grip, it can allow unwanted play in the assembly, leading to vibration, uneven wear on surrounding components, and eventually a loss of pumping efficiency or a more significant mechanical failure.
