The Wacker Neuson 5100012309 Ballast is a genuine OEM component designed for the RD45-140 tandem roller series. This ballast is sourced directly from Wacker Neuson and is built to the same specification as the original part fitted at the factory. It is compatible across the full RD45-140 family, including the RD45-140, RD45-140C, RD45-140 O, RD45-140o, RD45-140c, RD45-140 DPF, RD45-140c DPF, RD45-140o DPF, and their corresponding variants. When you order part number 5100012309, you are getting the correct OEM ballast with no guesswork on fitment.
Key Features
- Genuine OEM Mass and Material Specification — Manufactured to the exact weight and dimensional tolerances required by the RD45-140 platform, ensuring the ballast performs its designed loading function without deviation.
- Direct-Fit Replacement — Engineered to mount in the original ballast position on the RD45-140 frame, using the same attachment points as the part it replaces.
- Broad RD45-140 Family Coverage — Fits standard, C, O, o, DPF, and .3-suffix variants of the RD45-140 tandem roller, covering a wide range of machine configurations under a single part number.
- Correct Drum Loading for Compaction Performance — Proper ballast weight directly affects drum contact force and compaction output; a worn or missing ballast reduces compaction efficiency on asphalt and soil passes.
- Verified Wacker Neuson OEM Part — Part number 5100012309 is the genuine Wacker Neuson part, confirming you are not compromising on the weight specification critical to this machine's compaction rating.
The ballast on a tandem roller is a weighted component added to the machine's drum frame or chassis to increase the static load applied to the compaction surface. By raising the effective contact pressure of the drums against asphalt or soil, the ballast helps the roller achieve the required compaction depth and density in fewer passes. If a ballast is missing, damaged, or replaced with an incorrectly weighted substitute, the machine will deliver less compaction force than its rated specification, leading to under-compacted surfaces and potential rework.
