The Wacker Neuson Flat Steel Washer is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including PTS4V and PT-series trash pumps, CRT ride-on concrete trowels, and LTN/LTW-series light towers. As a direct factory replacement, this flat steel washer meets the original material and dimensional specifications used during manufacture. It is confirmed compatible across multiple machine series including the CRT36, CRT48, LTN6C, LTN6L, LTN6K, LTN8K, LTW20Z1, PT2, PT3, and PTS4V platforms. Keeping the correct hardware in place ensures proper clamping load, secure fastener seating, and long-term joint integrity across all supported applications.
Key Features
- Genuine OEM Steel Construction — Manufactured to the original hardness and thickness specification, ensuring correct load distribution under torque for this hardware application.
- Drop-In Hardware Replacement — Matches the original bore diameter and outer dimensions exactly, seating flush against mating surfaces without shimming or modification.
- Broad Multi-Platform Fitment — Compatible with PTS4V and PT-series trash pumps, CRT36 and CRT48 ride-on trowels, and the full LTN6/LTN8/LTW20Z1 light tower lineup.
- Protects Fastener Joints — Distributes clamp load evenly across the joint face, preventing fastener pull-through, surface deformation, and loosening under vibration.
- Sourced Direct from Wacker Neuson — Part number 5000025641 is an authenticated OEM part, ensuring you receive the correct grade of steel hardware for the application.
A flat steel washer sits between a fastener — such as a bolt head or nut — and the surface being clamped. Its primary job is to spread the clamping force over a larger contact area, which protects softer or thinner materials from being damaged as the fastener is tightened. On equipment that operates under sustained vibration, such as pumps, trowels, and light towers, washers also help prevent fasteners from backing out over time. Using the correct size and grade of washer is important: an undersized or incorrect-grade washer can allow a fastener to loosen, distort the mating surface, or lead to joint failure that causes secondary damage elsewhere in the assembly.
