The Wacker Neuson Shaft Seal 1.18 X 1.69 X.25, 2A is a genuine OEM component designed for the CT48BDT 1220mm/48in walk-behind concrete power trowel and the PT3B 75mm/3in centrifugal trash pump. As a direct OEM replacement, part is manufactured to the same tolerances and material specifications as the original, ensuring a proper fit at the shaft interface. This seal is the correct choice when servicing either machine and helps restore the sealing integrity the equipment depends on for continued operation.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original compound and dimensional spec, delivering the compression characteristics required to maintain a proper shaft seal under operating conditions.
- Dimensional Accuracy — 1.18 x 1.69 x .25 — The precise outer diameter, inner diameter, and width match the original shaft bore and housing dimensions, allowing the seal to seat correctly without modification.
- Cross-Application Fitment — Confirmed fitment across two distinct machine families: the CT48BDT walk-behind concrete power trowel and the PT3B 3-inch centrifugal trash pump.
- Prevents Fluid Ingress and Leakage — A worn or degraded shaft seal allows lubricant to escape and contaminants to enter along the shaft, accelerating bearing wear and leading to more costly repairs.
- Genuine OEM Part — Sourced directly through the Wacker Neuson parts network, so you can be confident you are installing the same component that left the factory with your machine.
A shaft seal forms a dynamic barrier between a rotating shaft and its surrounding housing, preventing lubricant from leaking out while blocking dirt, water, and debris from working in along the shaft. In a concrete power trowel like the CT48BDT, a healthy shaft seal keeps gearbox or bearing lubricant contained where it belongs, protecting the drive components from premature wear. In a trash pump like the PT3B, shaft seals also play a role in isolating the pump's wet end from the drive end, preventing fluid migration that can contaminate bearings or cause pump failure. When a shaft seal fails, the symptoms typically include visible leakage around the shaft, increased bearing temperatures, and accelerated wear — making timely replacement with the correct part essential to keeping the machine running as intended.
