The Wacker Neuson Lock Ring is a genuine OEM component designed for the BL744ch, BL744h, BL742h, BL744c, BL744 EX, and BL742 EX Backhoe Loader series. As a direct OEM replacement, this lock ring is sourced from Wacker Neuson and manufactured to the same standards as the original part installed at the factory. Verified compatibility across the BL742 and BL744 Backhoe Loader families means you can order with confidence knowing this is the correct part for your machine.
Key Features
- Genuine OEM Retention Integrity — Manufactured by Wacker Neuson to exact dimensional tolerances, ensuring the lock ring seats and secures as originally engineered — no guesswork on fit or holding force.
- Direct Drop-In Replacement — Designed to install in the same position and orientation as the original, with no reworking of surrounding components required.
- Broad Backhoe Loader Compatibility — Fits the BL742h, BL742 EX, BL744ch, BL744h, BL744c, and BL744 EX Backhoe Loader series, covering a wide range of Wacker Neuson backhoe applications.
- Prevents Component Loosening Under Load — A properly functioning lock ring holds adjacent components in place during operation; a worn or failed ring can allow unwanted movement, leading to accelerated wear on mating parts.
- Part Number 5100032781 Verified — Cross-reference this number directly against your machine's parts manual to confirm this is the correct lock ring for your specific BL series model and serial range.
A lock ring is a retaining component used to secure rotating or sliding assemblies in a fixed axial position, preventing unintended movement between mating parts during machine operation. In backhoe loader applications, lock rings are commonly found in drivetrain, hydraulic, and pivot assemblies where maintaining correct component alignment is critical to smooth, controlled performance. When a lock ring becomes worn, cracked, or loses its retaining tension, adjacent components can shift out of position — causing vibration, uneven wear, or loss of function in the affected assembly.
