Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's specified compound hardness and compression ratings, ensuring the seal performs at the pressures and temperatures these Backhoe Loaders generate in the field.
- Direct-Fit Replacement — Dimensioned to the original seat geometry, so the 5100033617 seats and seats correctly without reworking mating surfaces or housings.
- Broad BL700-Series Coverage — Confirmed fitment across the BL744ch, BL744h, BL742h, BL744c, BL744 EX, and BL742 EX Backhoe Loader models in a single part number.
- Leak Prevention — A correctly functioning seal ring maintains fluid containment and system pressure; a worn or cracked ring leads to fluid leaks, contamination ingress, and accelerated wear of surrounding components.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, so you're getting the same component that was installed at the factory — not an approximation.
A seal ring forms a pressure- and fluid-tight barrier between mating components, preventing hydraulic fluid, oil, or grease from escaping the assembly and stopping external contaminants from entering. In a Backhoe Loader, where hydraulic systems operate under sustained high pressure, even a minor seal failure can result in fluid loss, reduced actuator performance, and damage to pumps, cylinders, and valves. Replacing a worn or damaged seal ring promptly restores proper system integrity and protects the surrounding components from secondary damage.
