Wacker Neuson 5200003694 Drum Extension

The Wacker Neuson Drum Extension is a genuine OEM component designed for the RT and RTx series remote-controlled vibratory trench rollers, including the RT56-SC2, RT82-SC, RTx-SC2, RTLx-SC3, and RTKx-SC3 models. Sourced directly from Wacker Neuson, this drum extension meets the exact dimensional and material standards of the original part. It is a direct-fit replacement that installs without modification to the drum assembly on compatible trench roller configurations. Whether you are servicing a smooth-drum or padfoot setup across the SC2 and SC3 generations, part number covers an extensive range of machine configurations including Compatec-equipped variants.

Key Features

• Genuine OEM Construction — Manufactured to Wacker Neuson's original dimensional tolerances, ensuring the drum extension seats and secures correctly within the roller drum assembly.
• Direct-Fit Replacement — Engineered to replace the original drum extension on SC2 and SC3 generation trench rollers, aligning with existing drum mounting points and hardware.
• Broad Trench Roller Compatibility — Fits RT56-SC2, RT82-SC, RTx-SC2, RTLx-SC3, RTKx-SC3, and select HTC15 configurations, covering both standard and Compatec-equipped machines.
• Sustained Compaction Width Integrity — A correctly fitted drum extension maintains the roller's effective compaction width in trench applications; a worn or damaged extension can compromise drum alignment and compaction uniformity.
• Smooth and Padfoot Drum Applications — Compatible across smooth-drum and padfoot trench roller variants within the RT family, making it a versatile stock item for fleets running mixed configurations.

The drum extension on a vibratory trench roller widens the effective working width of the compaction drum, allowing the machine to cover more of the trench floor or sidewall area in a single pass. It bolts to the outer face of the drum and must maintain precise alignment to ensure even weight distribution and consistent compaction energy across the full drum width. When a drum extension becomes worn, cracked, or damaged, it can cause uneven compaction, accelerated drum bearing wear, and reduced performance in cohesive soil and backfill applications where uniform pass coverage is critical.
