The Wacker Neuson Seal Ring is a genuine OEM component designed for the BL744ch, BL744h, BL742h, BL744c, BL744 EX, and BL742 EX Backhoe Loader series. As a factory-sourced part, the is manufactured to the same material and dimensional standards as the original, ensuring a correct, trouble-free installation. If you're servicing any of the supported BL-series backhoe loaders, this is the correct seal ring to restore a proper fluid-tight connection and keep the machine operating at spec.
Key Features
- OEM Material Grade — Manufactured to the same compound and compression tolerances as the original seal, ensuring the ring seats and retains fluid pressure exactly as intended.
- Drop-In Installation — Dimensionally identical to the factory part, so the 5100033724 installs directly into the original seat without rework or modification to mating surfaces.
- Broad BL-Series Compatibility — Confirmed fitment across the BL742, BL744, BL744c, BL744 EX, and BL742 EX Backhoe Loader models, covering both standard and EX-configured machines.
- Leak Prevention — A correctly seated seal ring maintains system pressure and prevents fluid weeping at the joint; a worn or cracked ring typically results in visible leaks, pressure loss, and accelerated component wear.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so you can order with confidence that the part number, dimensions, and material specification are an exact match to what came off the machine.
A seal ring creates a fluid-tight barrier between two mating components — typically around a shaft, port, or housing joint — preventing hydraulic fluid, oil, or coolant from escaping the system. On a backhoe loader, these seals are found throughout the hydraulic circuit and drivetrain, where maintaining correct pressure is critical to boom, bucket, and stabilizer performance. When a seal ring degrades, hardens, or is damaged during service, the resulting leak can drop system pressure, contaminate surrounding components, and cause progressive damage if left unaddressed.
