The Wacker Neuson Collar Ring is a genuine OEM component designed for the APT4S and APT4T pump series, including standard, surge brake, electric brake, and cold weather configurations. As a factory-authorized part, the is manufactured to the exact tolerances required for proper fit and function within the pump assembly. This Collar Ring is a direct, like-for-like replacement, covering the full range of APT4S and APT4T variants — making it the correct choice whether you're servicing a standard skid-mounted unit or a cold weather electric brake model.
Key Features
- OEM Dimensional Accuracy — Manufactured to exact tolerances, ensuring the collar ring seats and retains components correctly within the pump assembly without slop or misalignment.
- Drop-In Replacement — Matches the original mounting profile of the 5200020150, allowing straightforward installation without modification to surrounding components.
- Broad APT Series Coverage — Fits APT4S and APT4T pump models across standard, surge brake, electric brake, and cold weather variants, consolidating your parts sourcing for the full pump lineup.
- Preserves Pump Integrity — A correctly fitted collar ring maintains proper component positioning within the pump; a worn or failed ring can lead to misalignment, increased wear on adjacent parts, and pump performance issues.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, so you get the same part that left the factory — not an approximation of it.
A collar ring is a retaining or locating component used to secure and position rotating or sliding parts within an assembly — in this case, within the APT pump unit. It keeps critical internal components aligned and held in place during operation, preventing unwanted movement that could cause premature wear or mechanical failure. When a collar ring becomes worn, cracked, or loses its grip, it can allow components to shift out of position, leading to vibration, accelerated damage to surrounding parts, and eventual pump failure.
