Wacker Neuson 5000178373 Taper Pin

The Wacker Neuson Taper Pin is a genuine OEM component designed for the PS2-1503L, PSA2-1503L, PSA2-2203L, and PS2-2203L submersible pumps. As a direct OEM replacement, it is manufactured to the exact dimensional tolerances required for proper installation and secure retention within the pump assembly. This part is sourced directly from Wacker Neuson, ensuring full compatibility across the PS2 and PSA2 submersible pump series it is engineered to fit.

Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to the exact taper angle and diameter specified by Wacker Neuson, ensuring the pin seats and locks correctly without slop or misalignment.
• Drop-In Installation — Matches the original bore geometry in the pump shaft assembly, allowing straightforward installation without reworking mounting points.
• Broad PS2 and PSA2 Series Coverage — Confirmed fitment across the PS2-1503L, PSA2-1503L, PS2-2203L, and PSA2-2203L submersible pump models.
• Secure Component Retention — A properly fitted taper pin locks rotating or sliding components in precise alignment; a worn or missing pin allows unwanted movement that accelerates internal wear throughout the pump.
• Verified OEM Part Number — Backed by Wacker Neuson part number 5000178373 for accurate cross-referencing against service manuals and parts diagrams.

A taper pin is a small but critical fastening element used to lock a shaft, impeller, or hub component in a fixed rotational position within an assembly. Its slightly conical profile wedges tightly into a matching tapered bore when driven home, creating a self-locking connection that resists vibration and axial movement during pump operation. When a taper pin shears, loosens, or goes missing, the secured component can shift or spin freely, leading to loss of pumping performance, accelerated wear on mating surfaces, and potential damage to the pump internals.
