The Wacker Neuson is a genuine OEM Drum Shockmount M16 designed for the RD27-100 and RD27-120 series tandem rollers. As a direct factory replacement, this shockmount meets the exact specifications of the original component and installs in the same M16 mounting position without modification. It is compatible across a wide range of RD27 configurations, including the RD27 Pro, RD27 Basic, and T4F-compliant variants. When your current mount shows signs of wear — cracking, hardening, or loss of damping — replacing it with a genuine Wacker Neuson part restores the drum's isolation characteristics and protects the machine's structural components from vibration fatigue.
Key Features
- Genuine OEM Damping Material — Manufactured to the same rubber compound and durometer rating as the original, ensuring consistent vibration absorption across the drum assembly.
- M16 Bolt Pattern, Direct Swap — Matches the OEM M16 mounting interface exactly, so the mount seats and torques correctly the first time.
- Broad RD27 Fitment — Verified fit for RD27-100 and RD27-120 tandem rollers, including Pro, Basic, and T4F configurations across multiple serial ranges.
- Protects Structural Components — A functioning shockmount isolates drum vibration from the frame; a deteriorated mount allows vibration to transfer directly into the chassis, accelerating wear on welds, bearings, and fasteners.
- Restores Compaction Consistency — Correct drum isolation keeps vibratory energy directed into the material being compacted, maintaining pass efficiency and surface finish quality on asphalt and soil.
A drum shockmount is the resilient isolator that sits between the vibratory drum and the machine's frame, absorbing and dampening the high-frequency vibration generated during compaction passes. By decoupling the drum from the chassis, the mount prevents excessive vibration from reaching the operator platform, hydraulic components, and structural welds. When a shockmount degrades — through rubber fatigue, oil contamination, or physical cracking — vibration transfer increases significantly, which can cause premature failure of surrounding hardware and a noticeable drop in compaction output as the drum loses its tuned operating characteristics.
