The Wacker Neuson Cap is a genuine OEM component designed for a wide range of Wacker Neuson walk-behind concrete power trowels and self-priming centrifugal trash pumps. This includes CT36 and CT48 series trowels — spanning fixed-speed, variable-speed, and CE-compliant configurations — as well as PT3A 3-inch trash pumps. As a factory-sourced part, the meets the exact material and dimensional standards set by Wacker Neuson, ensuring it seats and seals correctly on first installation. Whether you are servicing a CT36-8A, CT48-8A, CT36AGP, CT48ADP, CT36AVT, CT48ADT, or a PT3A pump, this cap is the correct factory replacement.
Key Features
- Genuine OEM Fit and Material Grade — Sourced directly from Wacker Neuson, this cap is manufactured to the same dimensional tolerances and material specification as the original, so it seats flush and holds without play or gap.
- Broad Cross-Series Compatibility — Verified for CT36 and CT48 walk-behind concrete trowels across fixed-speed, variable-speed, and CE configurations, as well as the PT3A 3-inch centrifugal trash pump.
- Drop-In Replacement — Designed to replace the original cap with no modification to the housing or surrounding hardware, making it suitable for field service and scheduled maintenance alike.
- Protects the Component It Covers — A correctly fitted cap keeps contaminants, moisture, and debris away from the underlying port, shaft, or reservoir — preventing accelerated wear in the components it protects.
- Verified Part Number — Cross-reference 5000074745 against your machine's serial number and model to confirm correct application before ordering.
A cap serves as a protective closure for an exposed port, shaft end, reservoir opening, or housing access point on the machine. Its job is to maintain a sealed or covered interface, blocking the ingress of dirt, water, and debris that would otherwise degrade internal components. When a cap is cracked, missing, or no longer seating correctly, the underlying area becomes vulnerable — leading to contamination, fluid loss, or premature wear of the parts it was designed to protect. Replacing a damaged or lost cap promptly is a low-cost step that preserves the integrity of more expensive assemblies.
