The Wacker Neuson Check Disc is a genuine OEM component designed for the BH40, BH55, BH65, and BH55rw breaker series, as well as BS62-2 and BS68-2 rammer models. As a direct factory-sourced part, it meets the original engineering specification and installs as a like-for-like replacement with no adaptation needed. Compatibility spans a wide range of configurations across the BH and BS model families, including Sunbelt-designated rammer variants, making a versatile stock item for fleet operators and service technicians alike.
Key Features
- Genuine OEM Disc Geometry — Manufactured to Wacker Neuson's original dimensional tolerances, ensuring the check disc seats and seals correctly within the valve circuit every time.
- Direct Drop-In Replacement — Matches the original mounting profile and disc diameter, allowing straightforward installation without machining or shimming.
- Broad Model Coverage — Fits BH40, BH55, BH55rw, BH65, and ND-40 breaker families plus BS62-2 and BS68-2 rammer series, including Sunbelt variants.
- Consistent One-Way Flow Control — A correctly functioning check disc maintains proper fluid or air directionality in the circuit; a worn disc allows backflow that degrades impact energy and cycle rate.
- Verified Part Number — Sourced directly under Wacker Neuson part number 5100065738, eliminating fitment guesswork when cross-referencing against machine service records.
A check disc is a one-way valve component that allows fluid or air to flow in a single direction while blocking reverse flow within the breaker or rammer's internal circuit. It plays a critical role in maintaining the pressure differential that drives the tool's impact mechanism — without it functioning correctly, the machine loses striking force, cycles inconsistently, or stalls under load. When the disc wears, cracks, or deforms, backflow occurs and performance drops noticeably, making timely replacement essential to keeping the tool operating at rated output.
