The Wacker Neuson 5100012089 Engine Suspension is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers, including standard, open-ROPS, and canopy configurations. As a direct OEM replacement, this part is manufactured to the same specifications as the original, ensuring proper fitment across the full range of covered RD40 and RD45 models. Compatibility extends to both US-market and international variants of these tandem rollers, covering multiple production generations including.3-series machines. Always confirm your machine's model and serial number before ordering to ensure you receive the correct suspension mount for your unit.
Key Features
- Genuine OEM Isolation Quality — Engineered to match the original durometer and load-bearing rating of the factory mount, maintaining proper vibration damping between the engine and frame.
- Drop-In Replacement — Mounts to the same bolt pattern as the original, allowing straightforward installation without reworking surrounding hardware or brackets.
- Broad RD40 and RD45 Coverage — Fits RD40-130 and RD45-140 tandem rollers across standard, open-ROPS (O), canopy (C), US-market, and .3-generation variants.
- Protects Engine and Frame Integrity — A correctly functioning engine suspension absorbs operational vibration; a worn or collapsed mount transfers that vibration directly to the frame, accelerating wear on surrounding components and fasteners.
- Operator Comfort and Machine Control — Proper engine isolation reduces vibration transmitted through the machine structure, supporting steadier machine operation during compaction passes.
The engine suspension — also known as an engine mount or anti-vibration mount — is the resilient bushing or bracket assembly that connects the engine to the machine's main frame while absorbing the vibration generated during operation. On a tandem roller like the RD40-130 and RD45-140, where high-frequency compaction forces are constantly present, this component plays a critical role in preventing excessive vibration from reaching the frame, fuel and hydraulic lines, and operator controls. When an engine suspension wears out or deteriorates, it loses its ability to dampen movement, leading to increased structural stress, loosened fasteners throughout the machine, and a rougher, harder-to-control ride that can affect compaction quality and machine longevity.
