Wacker Neuson 5000079009 Shaft Seal 24 X 50 X 10 2B

The Wacker Neuson is a genuine OEM Shaft Seal 24 X 50 X 10 2B designed for the CT30, CT36, and CT48 series walk-behind concrete power trowels. Sourced directly from Wacker Neuson, this seal carries the same specifications as the part installed at the factory, ensuring a correct fit in your machine. It is compatible with a wide range of CT series configurations including gasoline, diesel, electric, and variable-speed models in both standard and CE variants across 30-inch, 36-inch, and 48-inch rotor sizes.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's exact dimensional tolerances (24 x 50 x 10 mm) with a double-lip 2B profile that maintains a positive seal under the rotational loads specific to concrete trowel drivetrains.
• Drop-In Fitment for CT Series Trowels — Matches the original shaft bore and housing dimensions, allowing straightforward installation without modification to the seal housing or shaft journal.
• Broad CT Series Compatibility — Fits CT30, CT36, and CT48 walk-behind trowels across gasoline (AGP, AGT), diesel (ADP, ADT, BDT), electric (EDT), and variable-speed (AVP, AVT) variants, including CE-marked configurations.
• Prevents Lubricant Loss and Contamination — A worn or compromised shaft seal allows grease or oil to escape the gearbox while drawing in concrete slurry and moisture, accelerating bearing wear and leading to costly drivetrain damage.
• Fuel and Fluid Resistant Sealing Material — The seal compound is formulated to resist the gear lubricants used in CT series trowel gearboxes, maintaining its sealing lip integrity through extended service cycles.

A shaft seal is a precision ring fitted around a rotating shaft where it exits a gearbox or bearing housing. Its job is to keep lubricant inside the housing while blocking contaminants — water, concrete dust, and slurry — from entering. In a walk-behind concrete trowel, the rotor shaft turns continuously under load and in a wet, abrasive environment, making the shaft seal one of the higher-wear consumable components in the drivetrain. When the seal fails, lubricant escapes, bearings run dry, and abrasive material works its way into the gearbox — damage that typically progresses quickly and can result in full gearbox replacement if left unaddressed.
