The Wacker Neuson Flat Washer is a genuine OEM flat washer designed for CT36 and CT48 walk-behind concrete trowels and PT2 series centrifugal trash pumps. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory. It fits a wide range of CT36 and CT48 models — including AGP, ADP, AVP, and AVT configurations — as well as PT2A, PT2B, PT2R, PT2Y, and PTK2 trash pump variants. When you order part number, you get an exact-match replacement with no guesswork on fitment.
Key Features
- Genuine OEM Material Grade — Manufactured to Wacker Neuson's original hardness and dimensional tolerances, ensuring correct load distribution and clamping force at every fastened joint.
- Drop-In Installation — Matches the original hole diameter, outer diameter, and thickness of the factory washer, so it seats correctly against mating hardware without shimming or modification.
- Broad Model Coverage — Verified fit across CT36 and CT48 walk-behind trowel families (AGP, ADP, AVP, AVT variants) and PT2 series centrifugal trash pumps, including the PTK2 pump-only unit.
- Protects Fastener Integrity — A properly sized flat washer distributes clamping load evenly across the mating surface, preventing bolt heads and nuts from pulling through or deforming the housing over time.
- Verified Part Number Traceability — Part number 5001006311 cross-references directly to Wacker Neuson's OEM parts catalog, so you can order with confidence that this is the correct item for your machine.
A flat washer serves as a load-spreading interface between a fastener — such as a bolt head or nut — and the surface it clamps against. By distributing the clamping force over a wider area, the washer prevents surface damage, reduces the risk of fastener loosening due to vibration, and helps maintain the correct torque retention over time. On high-vibration equipment like concrete trowels and trash pumps, even a small hardware component like this plays a meaningful role in keeping assemblies tight and structurally sound. A missing or worn washer can accelerate wear on housing surfaces and allow critical fasteners to back out during operation.
