Wacker Neuson 5000171665 820MM Smooth Drum

The Wacker Neuson 820MM Smooth Drum is a genuine OEM compaction drum designed for the RT / RTL / RTK / RTx series remote-controlled vibratory trench rollers, including the RT56-SC, RT82-SC, RT82-SC2, RTLx-SC3, RTKx-SC3, and RTx-SC2 families. As a direct OEM replacement, part is manufactured to the same standards as the original drum and installs without modification to factory drum mounting points. This smooth drum configuration is suited for trench compaction applications where a consistent, uninterrupted compaction surface is required. Confirming your machine number against the fitment list before ordering ensures you receive the correct drum for your specific roller configuration.

Key Features

• Genuine OEM Steel Construction — Manufactured to Wacker Neuson's original drum wall thickness and diameter specifications, maintaining consistent compaction force transfer across the full 820MM drum width.
• Smooth Drum Surface — Flat, uninterrupted compaction face delivers uniform ground pressure, ideal for finishing cohesive soils and trench backfill without surface scarring.
• Broad RT Series Compatibility — Fits RT56-SC, RT82-SC, RT82-SC2, RTLx-SC3, RTKx-SC3, and RTx-SC2 trench roller families, including Compatec-equipped variants and EU-spec machines.
• Drop-In Drum Replacement — Mounts to existing drum shaft and bearing interfaces on the trench roller frame, aligning with OEM hardware for a straightforward swap in the field or shop.
• Restore Full Compaction Output — A worn, cracked, or out-of-round drum reduces contact area and compaction efficiency; replacing with part 5000171665 restores the roller's rated compaction performance in trench and cohesive soil applications.

The compaction drum is the primary working element of a vibratory trench roller — it contacts the ground surface directly and transmits both the static weight and the high-frequency vibration generated by the exciter assembly into the soil. On a smooth drum model, the unbroken cylindrical surface distributes ground pressure evenly, which is critical for achieving uniform density in trench backfill and cohesive soil compaction. When a drum becomes deformed, cracked, or excessively worn, it creates uneven contact with the compaction surface, resulting in inconsistent density readings, failed compaction tests, and the need to rework completed lifts.
