The Wacker Neuson is a genuine OEM Crank Holder Bushing designed for the RD7 series walk-behind tandem rollers, including RD7H, RD7He, and RD7H-ES configurations. Sourced directly from Wacker Neuson, this part meets the exact tolerances and material specifications of the original component installed at the factory. It is a verified direct replacement for all RD7 tandem roller variants listed in the Wacker Neuson parts system, covering both North American and EU-market machines. If your RD7 series roller is showing signs of crank holder wear, part number is the correct OEM solution.
Key Features
- OEM-Grade Bushing Material — Manufactured to Wacker Neuson's original bore tolerances and surface finish specifications, ensuring proper crank holder retention and load distribution within the drum drive assembly.
- Drop-In Fitment for RD7 Variants — Matches the original mounting dimensions exactly, seating into the crank holder without machining or modification to the housing bore.
- Broad RD7 Series Coverage — Compatible with RD7H, RD7He, and RD7H-ES tandem rollers across multiple machine numbers, including EU-market and North America-only configurations.
- Drum Drive Integrity — A worn or failed crank holder bushing causes play and misalignment in the drum exciter assembly, leading to vibration irregularities and uneven compaction output — this replacement restores correct operation.
- Genuine Wacker Neuson OEM Part — Supplied as an authentic Wacker Neuson component, traceable to the original part number 5000112274 in the official parts catalog.
The crank holder bushing supports and locates the eccentric crankshaft within the drum assembly of the tandem roller. It acts as a wear interface between the rotating crank and its housing, absorbing radial loads generated during vibration cycles. When this bushing wears, clearance builds up around the crank, causing inconsistent vibration output, increased stress on surrounding components, and a noticeable drop in compaction performance — making timely replacement essential to keeping the drum exciter system operating correctly.
