Wacker Neuson 5100011543 Washer — Genuine OEM Replacement for RD and RC Series Compactors

The Wacker Neuson Washer is a genuine OEM replacement built for the RD18-100 C, RD40-130, RD45-140, and RC110 series tandem rollers and compactors. Sourced directly from Wacker Neuson, this washer is manufactured to the exact tolerances and material specifications used in original production, ensuring a consistent, accurate fit every time. It is compatible across an extensive range of RD and RC series machines, including DPF variants, cab and ROPS configurations, and US-market models, making it a versatile stock item for fleet operators and service shops alike.

Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to the exact thickness, inner diameter, and outer diameter specifications used at the factory, ensuring the washer seats and functions as intended in the assembly.
• Direct Drop-In Replacement — Matches the original mounting position and hardware interface with no rework or shimming required during installation.
• Broad RD and RC Series Coverage — Fits RD18-100 C, RD40-130, RD45-140, RC110, and RC110P machines, including standard, cab, ROPS, open drum, and DPF-equipped variants across multiple build series.
• Load Distribution Integrity — A correctly fitted washer maintains even clamping force across fastened joints; a worn or undersized washer can allow bolt movement, surface damage, and loosening under vibration typical of compaction equipment.
• Authentic Wacker Neuson Part — Carries part number 5100011543 and is backed by Wacker Neuson's genuine OEM parts program, giving you full traceability and confidence in the component you are installing.

A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it clamps against. By spreading the clamping force across a wider area, the washer prevents the fastener from pulling through or damaging softer mating surfaces and helps maintain consistent tension in the joint. On compaction equipment like tandem rollers, where high-amplitude vibration is a constant operating condition, washers play an important role in keeping critical fastened connections secure; a worn, deformed, or incorrectly sized washer can allow fasteners to loosen progressively, leading to misalignment, surface wear, or component failure over time.
