The Wacker Neuson Shim 42 X 52 X 0.1 is a genuine OEM component designed for the RD25 Hydrostatic Double Drum Vibratory Roller. Sourced directly from Wacker Neuson, this shim matches the exact dimensional specification called out in the original build — 42 mm inner diameter, 52 mm outer diameter, and a 0.1 mm thickness that leaves no margin for error. When precise axial or radial clearance is critical to drivetrain or drum assembly performance, substituting an incorrectly sized shim risks premature wear, misalignment, and costly follow-on repairs. Having the correct OEM part on hand keeps the rebuild on spec and the machine back in service without second-guessing the fit.
Key Features
- Exact Dimensional Accuracy — At just 0.1 mm thick with a 42 x 52 mm profile, this shim delivers the precise clearance specification the RD25 drivetrain demands — no filing, no stacking, no guesswork.
- Genuine OEM Part — Manufactured by Wacker Neuson to the same tolerances as the original production component, ensuring the shim seats and performs exactly as engineered.
- Direct-Fit Replacement — Part number 5000203639 maps directly to the RD25 assembly, dropping into position without alteration or additional machining.
- Verified RD25 Fitment — Confirmed for the RD25 Hydrostatic Double Drum Vibratory Roller, keeping your rebuild aligned with the correct parts diagram for that machine.
- Protects Adjacent Components — A correctly spec'd shim maintains proper bearing and shaft alignment; an undersized or oversized substitute accelerates wear on surrounding components and can lead to assembly failure under load.
A shim is a thin, precision-ground spacer used to set and maintain exact clearances between mating components — such as bearings, shafts, housings, or drum assemblies. In a vibratory roller like the RD25, where drivetrain components operate under sustained vibration and load, maintaining the correct gap or preload is essential to smooth operation and component longevity. When a shim wears down, deforms, or is replaced with the wrong thickness, misalignment follows — leading to uneven bearing load, accelerated wear, and potential assembly damage that goes well beyond the cost of the shim itself.
