The Wacker Neuson is a genuine OEM Washer 5/16 designed for the PDT2, PDT3, PDI2, and PDI3 series diaphragm trash pumps, as well as CRT36 ride-on concrete trowels. As a direct factory replacement, part meets the original assembly specifications for every machine it serves. This washer fits across a wide range of model variants within the PDT and PDI pump families, as well as the CRT36ASO and CRT36ASN trowel configurations, making it a versatile service part to keep on hand.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact thickness and inner diameter of the original, ensuring proper clamping load and sealing performance in pump and trowel assemblies.
- Direct Drop-In Replacement — Installs in the same position as the factory washer with no rework to mating hardware or fastener torque sequences.
- Broad Fitment Across PDT and PDI Pump Families — Confirmed for 50mm/2in and 75mm/3in diaphragm trash pump variants including PDT2, PDT2A, PDT2B, PDT3, PDT3A, PDI2, PDI2A, PDI3, and PDI3A series machines.
- CRT36 Trowel Compatibility — Also confirmed for CRT36ASO overlapping and CRT36ASN non-overlapping 915mm ride-on concrete trowel models.
- Prevents Fastener Damage — A properly sized washer distributes clamping load evenly, protecting mating surfaces from deformation and preventing fastener loosening under vibration.
A washer serves as a load-distributing interface between a fastener and the surface it secures. By spreading clamping force across a wider area, it protects softer or machined surfaces from being damaged as bolts or nuts are tightened down. In equipment subject to continuous vibration — such as diaphragm pumps and ride-on trowels — a washer also helps resist fastener loosening over time. When a washer is missing, deformed, or the wrong size, it can lead to uneven clamping, surface galling, or fasteners that back out during operation.
