Wacker Neuson 5000115926 Shaft Seal 1.625 X 2.252 X .313

The Wacker Neuson is a genuine OEM Shaft Seal 1.625 X 2.252 X.313 designed for the CRT36 and CRT48 series ride-on concrete trowels. Sourced directly from Wacker Neuson, this seal meets the exact dimensional and material specifications set at the factory, ensuring a correct, leak-free installation every time. It is compatible across a broad range of CRT models including the CRT36-23K-H, CRT36-24A-H, CRT36-24A-E, CRT36-25K-H, CRT48-25K-L, CRT48-25K-H, CRT48-31V-H, CRT48-31V-E, CRT48-31V-ES, and CRT48-31V-ES-E. When seal integrity matters on a productive finishing machine, trust the part built specifically for the job.

Key Features

• Exact Dimensional Spec: — Manufactured to the precise 1.625 x 2.252 x .313 inch profile, ensuring a flush, compression-correct seat against the shaft and bore with no shimming or fitting required.
• OEM Material Grade: — As a genuine Wacker Neuson component, the seal compound is matched to the operating temperatures and lubricant exposure found in CRT ride-on trowel driveline applications.
• Broad CRT Series Coverage: — Fits both 36-inch and 48-inch CRT models across high-speed, low-speed, and electronic steering configurations, making it a practical stock item for fleets running multiple trowel variants.
• Protects Driveline Components: — A healthy shaft seal keeps lubricant in and contaminants out; a worn or leaking seal accelerates bearing wear and can lead to costly driveline damage on a machine mid-pour.
• Direct OEM Replacement: — Part number 5000115926 cross-references directly to the original seal position, so installation follows the same procedure as the factory-fitted component.

A shaft seal creates a dynamic barrier between a rotating shaft and its surrounding housing, retaining the lubricant that keeps bearings and gears operating smoothly while blocking concrete slurry, water, and abrasive debris from entering the driveline. On a ride-on concrete trowel like the CRT36 and CRT48, the seal works under continuous rotational load during finishing passes, making material integrity and dimensional accuracy critical. When the seal begins to leak or deteriorate, lubricant loss and contamination quickly follow, putting bearings and adjacent components at risk of premature failure.
