The Wacker Neuson Pin 5M6 x 40 Dowel is a genuine OEM component designed for a broad range of Wacker Neuson RD-series tandem rollers, including the RD12, RD16, and RD27 families. As a direct OEM replacement, this dowel pin is manufactured to exact dimensional tolerances, ensuring correct alignment and positioning within the assemblies where it is used. Fitment extends across multiple RD12, RD16, and RD27 configurations, as well as select CB14B series compactors and BTS cut-off saw models. Always confirm your machine model and serial number against the fitment list before ordering.
Key Features
- Exact OEM Dimensional Tolerance — Manufactured to the precise 5M6 x 40 specification, ensuring correct press-fit or slip-fit seating without the risk of misalignment that an undersized or oversized pin would cause.
- Direct Drop-In Installation — Matches the original bore diameter and length exactly, so the pin seats into existing housings and bores without reworking or shimming.
- Wide RD-Series Compatibility — Confirmed fitment across RD12, RD16, and RD27 tandem roller variants, including standard, foldable ROPS, and hydrostatic configurations, plus select CB14B and BTS models.
- Structural Alignment Integrity — A correctly fitted dowel pin maintains precise component-to-component positioning; a worn or missing pin allows components to shift under load, leading to accelerated wear on surrounding bores and fasteners.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number used in OEM assembly, so you can order with confidence that the specification matches your machine.
A dowel pin is a precision-ground cylindrical fastener used to locate and align two or more components relative to each other, keeping them in a fixed, repeatable position regardless of vibration or load cycles. In heavy compaction equipment like tandem rollers, dowel pins are critical wherever housings, covers, or structural members must register accurately — misalignment caused by a missing or damaged pin can result in uneven loading on bolted joints, premature bore wear, and potential fastener failure. Replacing a worn or lost dowel pin promptly restores the designed alignment geometry and protects the integrity of the surrounding assembly.
