Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original compound and compression specifications, ensuring the seal performs at the correct interference fit and temperature range for this application.
- Direct Drop-In Replacement — Dimensionally identical to the original, seating into the same bore and mating surfaces without rework or modification to the housing.
- Broad BL700-Series Coverage — Fits BL744ch, BL744h, BL742h, BL744c, BL744 EX, and BL742 EX Backhoe Loaders under a single part number.
- Prevents Fluid Loss and Contamination — A correctly seated oil seal keeps lubricant where it belongs and blocks dirt and debris from entering the sealed cavity, protecting adjacent bearings and rotating components.
- Genuine OEM Part — Supplied as an authorized Wacker Neuson replacement, backed by the manufacturer's part number verification and quality control process.
An oil seal creates a dynamic barrier between a rotating shaft and a stationary housing, retaining lubricating oil on one side while preventing external contaminants such as dirt, water, and debris from entering on the other. In a backhoe loader, oil seals are used throughout the drivetrain, axles, and hydraulic system — wherever a rotating or reciprocating component passes through a housing wall. When an oil seal wears, hardens, or becomes damaged, it allows oil to leak out and contaminants to work in, accelerating wear on bearings and other precision components and ultimately leading to more extensive and costly repairs if left unaddressed.
