Wacker Neuson 5000010375 Washer B10.5 Flat

The Wacker Neuson Washer B10.5 Flat is a genuine OEM fastener component designed for a broad range of Wacker Neuson equipment, including CRT and CT ride-on and walk-behind concrete trowels, RD tandem rollers, G-Series mobile generators, LTN and LTW light towers, HI indirect air heaters, DPU reversible vibratory plate compactors, BFS floor saws, AR external concrete vibrators, and PTS trash pumps. As a genuine OEM part, the is manufactured to Wacker Neuson's exact dimensional and material specifications, ensuring it seats and functions correctly every time. This washer serves as a direct-fit replacement sourced from the original equipment manufacturer, covering an exceptionally wide range of machines across multiple product families. Confirm your model number against the fitment list before ordering to ensure the is the correct washer for your application.

Key Features

• Exact B10.5 Dimensional Spec — Manufactured to the precise inside diameter and thickness of the original washer, ensuring correct load distribution across the fastener joint without over- or under-seating.
• Genuine Wacker Neuson OEM Quality — Produced to the same material grade as the factory-installed washer, resisting deformation under the clamping loads and vibration levels found in concrete, compaction, and power-generation equipment.
• Broad Cross-Family Fitment — A single part number covering CRT and CT concrete trowels, RD tandem rollers, DPU reversible plate compactors, G-Series and GV generators, LTN and LTW light towers, HI indirect air heaters, BFS floor saws, AR external vibrators, and PTS trash pumps — simplifying parts stocking across a mixed fleet.
• Protects Mating Surfaces — Distributes fastener clamp force evenly, preventing surface damage, fastener pull-through, and loosening caused by vibration over time — particularly important on high-vibration compaction and concrete finishing equipment.
• Direct OEM Replacement — Drops into the same position as the original with no modification to surrounding hardware, keeping assembly torque specs and joint integrity intact.

A flat washer functions by spreading the clamping load of a bolt or nut over a wider surface area, preventing the fastener from digging into or pulling through the material it secures. On equipment like concrete trowels, tandem rollers, and vibratory plate compactors — where continuous vibration places constant stress on every bolted joint — washers play a critical role in keeping fasteners properly seated and assemblies structurally sound. When a washer deforms, corrodes, or goes missing, the fastener loses its correct preload, which can lead to loosening, accelerated wear of the mating components, and potential structural failure of the joint under operating loads.
