The Wacker Neuson Disk Spring is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers, including standard, C, and O configurations across both the original and.3 production series. As a factory-authorized part, the is manufactured to the same specifications as the original, ensuring a direct drop-in fit with no guesswork on compatibility. This Disk Spring covers an extensive range of Wacker Neuson tandem roller variants, making it a dependable choice whether you're servicing an RD40-130 C, an RD45-140 O, or any of the.3-series models. When it's time to restore your machine to full working condition, sourcing a genuine OEM part like this one means the job is done right the first time.
Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to exact load and deflection tolerances, ensuring the Disk Spring delivers consistent clamping or preload force as designed.
- Direct Drop-In Replacement — Matches the original mounting profile and stack height, so installation fits within the existing assembly without modification to surrounding hardware.
- Broad Tandem Roller Compatibility — Fits twelve Wacker Neuson RD40-130 and RD45-140 variants, covering standard, C, and O configurations in both the original and .3 production series.
- Sustained Compaction Performance — A correctly functioning Disk Spring maintains proper mechanical preload in the drum or drive assembly; a worn or fatigued spring leads to inconsistent force transfer and reduced compaction output.
- Verified Part Number Match — Supplied under Wacker Neuson part number 5100012016, cross-referenced against all listed model numbers for confirmed accuracy before purchase.
A disk spring — also known as a Belleville spring or conical washer spring — is a precision-engineered component that stores and releases mechanical energy under axial load. In compaction equipment like tandem rollers, disk springs are commonly used to maintain consistent preload on bearings, clutch packs, or drive assemblies, absorbing vibration and keeping critical components under the correct amount of tension during operation. When a disk spring fatigues, cracks, or loses its load rating, the assembly it supports can develop play, generate excessive heat, or fail to transfer force correctly — leading to accelerated wear on surrounding components and a drop in overall machine performance.
