The Wacker Neuson Hub Seal Ring is a genuine OEM component designed for the BL744 and BL742 series backhoe loaders, including the BL744ch, BL744h, BL742h, BL744c, BL744 EX, and BL742 EX models. Sourced directly from Wacker Neuson, this part meets the exact material and dimensional specifications of the original — ensuring a proper seat and seal at the hub. If your machine is showing signs of hub grease loss or contamination ingress, replacing the seal ring with the correct OEM part is the straightforward fix.
Key Features
- OEM Seal Material and Compression Integrity — Manufactured to Wacker Neuson's original compound and compression specifications, so the ring seats and retains its seal under the rotational loads and temperature cycles a backhoe hub produces.
- Drop-In Hub Fitment — Engineered to the exact bore diameter and profile of the original, seating cleanly into the hub housing without modification or reworking of the surrounding components.
- Confirmed Fitment Across BL744 and BL742 Series — Compatible with the BL744ch, BL744h, BL742h, BL744c, BL744 EX, and BL742 EX backhoe loaders, covering the full current generation of Wacker Neuson's BL-series machines.
- Keeps Hub Lubrication Where It Belongs — A correctly functioning hub seal ring retains grease within the hub assembly and blocks dirt, debris, and moisture from reaching the bearing surfaces — protecting the hub from premature wear.
- Verified Part Number 5100032609 — Cross-reference this number against your machine's parts manual before ordering to confirm applicability to your specific serial number range.
A hub seal ring forms the barrier between the rotating hub assembly and the outside environment. Its job is to keep lubricating grease inside the hub — where it protects the bearing surfaces — while preventing abrasive particles, water, and contamination from working their way in. When the seal ring wears, cracks, or loses its compression fit, grease migrates out and contaminants migrate in, accelerating bearing wear and eventually leading to hub damage that is far more costly to repair. Replacing a faulty hub seal ring early is one of the most straightforward preventive maintenance tasks on a backhoe loader axle.
