The Wacker Neuson Exciter Gear is a genuine OEM component designed for RT560, RT820, and RT820HT vibratory trench rollers. Sourced directly from Wacker Neuson, this part meets the exact design and material specifications of the original component. It is confirmed to fit multiple RT560 and RT820 series configurations, including RT820HT high-tip variants. When you order by part number, you can trust you are getting the correct gear for your machine.
Key Features
- Genuine OEM Gear Geometry — Manufactured to the original tooth profile and hardness spec, ensuring proper mesh and load transfer within the exciter assembly.
- Drop-In Replacement — Engineered to the same dimensions as the original, allowing direct installation into the exciter housing without rework or shimming.
- Broad RT Series Fitment — Compatible with RT560 and RT820 vibratory trench rollers across multiple serial number ranges, including RT820HT high-tip models.
- Sustained Vibration Output — A correctly functioning exciter gear maintains consistent eccentric weight rotation, preserving the compaction force and frequency the roller is rated to deliver.
- Wear-Critical Component — Gear wear in the exciter assembly leads to uneven vibration, increased bearing load, and progressive drivetrain damage; replacing at first sign of wear protects the broader assembly.
The exciter gear is a core element of the vibratory system inside a trench roller's drum assembly. It transfers rotational force from the drive to the eccentric weights, generating the oscillating compaction energy that allows the roller to densify cohesive soils and trench backfill. When the exciter gear is worn, chipped, or broken, vibration output becomes irregular or ceases entirely, leaving the machine unable to achieve specified compaction depth and putting added stress on surrounding drivetrain components.
