The Wacker Neuson is a genuine OEM Set Screw 5/16-18 X 1/4 designed for the CRT36ASO and CRT36ASN 915mm/36-inch ride-on concrete trowels and the PDT3 75mm/3-inch diaphragm trash pump. Sourced directly from Wacker Neuson, this fastener matches the original specification for thread form, engagement length, and drive type — ensuring a secure, rattle-free hold in the applications it was engineered for. Using the correct OEM set screw helps maintain proper component positioning and prevents the loosening or slippage that can result from an incorrectly sized fastener. Keep part number on hand as a service spare whenever performing maintenance on these machines.
Key Features
- Correct Thread Specification: — 5/16-18 UNC thread form and 1/4-inch engagement length match the original fastener exactly, threading in cleanly without chasing or rework.
- Genuine OEM Part: — Supplied by Wacker Neuson to the same material grade and drive geometry as the factory-installed fastener, so holding force and torque capacity are consistent with design intent.
- Verified Fitment: — Confirmed for the CRT36ASO and CRT36ASN 36-inch ride-on trowels and the PDT3 3-inch diaphragm trash pump — two distinct machine families covered by a single part number.
- Prevents Component Slippage: — A properly seated set screw locks rotating or sliding components in position; a worn or missing one allows unwanted movement that can accelerate wear on adjacent parts.
- Direct Service Replacement: — Installs using standard hex key tooling with no additional hardware or modification needed, keeping maintenance straightforward in the field or shop.
A set screw is a headless fastener threaded fully through a collar, hub, or housing to bear directly against a shaft or mating surface, locking a component in a fixed rotational or axial position. On ride-on concrete trowels such as the CRT36 series, set screws are commonly used to secure drive components and linkage hardware against the vibration and torque loads generated during finishing passes. On diaphragm trash pumps like the PDT3, they serve a similar clamping role in pump and drive assemblies. When a set screw loosens or strips, the component it secures can shift under load, leading to accelerated wear, misalignment, or loss of function until the fastener is replaced.
