Wacker Neuson 5100032541 Belleville Washer

The Wacker Neuson is a genuine OEM Belleville Washer designed for the BL744ch, BL744h, BL742h, BL744c, BL744 EX, and BL742 EX Backhoe Loader series. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. It is a direct-fit replacement for the models listed above, with no adaptation required to match the original mounting configuration. Keep part number on hand as a scheduled service item or for immediate replacement when the original shows signs of fatigue or deformation.

Key Features

• Genuine OEM Spring Load Accuracy — Manufactured to the precise spring rate and load curve of the original, ensuring consistent clamping force across the full compression cycle.
• Direct-Fit Replacement — Matches the original bore, outer diameter, and cone angle of the factory-installed washer for straightforward installation in the existing fastener stack.
• Broad Backhoe Loader Compatibility — Confirmed fitment across the BL742, BL744, BL744c, and BL744 EX Backhoe Loader families, covering both standard and EX configurations.
• Sustained Clamping Performance — A correctly functioning Belleville Washer maintains bolt preload under vibration and thermal cycling; a fatigued or flattened washer allows joint loosening that can lead to component damage over time.
• OEM Material Integrity — Produced from the same hardened spring steel specification as the original, resisting set and deformation through repeated loading cycles in demanding earthmoving conditions.

A Belleville washer — also called a conical spring washer or disc spring — is a precision-formed, cone-shaped ring that acts as a spring element within a bolted joint. When compressed, it stores mechanical energy that continuously pushes back against the fastener, maintaining clamp load even as the assembly experiences vibration, shock loads, or temperature changes. In heavy equipment like backhoe loaders, this function is critical: without a serviceable Belleville Washer, fasteners in high-stress joints can gradually back off, leading to play, misalignment, or accelerated wear in the connected components. Replacing a flattened or cracked washer with a genuine OEM part restores the engineered preload to the joint and protects the surrounding hardware.
