The Wacker Neuson 5100011535 is a genuine OEM Cap Nut designed for the RD-series tandem rollers, covering the RD18, RD24, RD27, RD28, RD40, and RD45 model families. As a factory-sourced component, it is manufactured to the same specifications as the original part it replaces, ensuring a correct, secure installation without guesswork. This Cap Nut is confirmed compatible across a broad range of RD tandem roller configurations, including standard, open ROPS, canopy, DPF, and electric variants. If you are servicing an RD-series tandem roller and need a dependable replacement, part number 5100011535 is the correct OEM choice.
Key Features
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this Cap Nut meets the exact thread pitch, dimensional tolerancing, and material hardness of the original hardware, so fastener integrity is never compromised.
- Drop-In Hardware Replacement — Engineered to thread directly onto the same stud or bolt interface as the original, matching the head geometry and torque specification of the factory fastener.
- Broad RD-Series Coverage — Fits RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers across standard, open ROPS, canopy, DPF-equipped, and electric configurations — one part number serves the full family.
- Structural Clamping Integrity — A correctly torqued Cap Nut keeps assemblies firmly secured under the continuous vibration loads generated during asphalt and soil compaction; a stripped or missing cap nut can allow critical components to loosen in operation.
- Verified OEM Part Number — Cross-reference 5100011535 against your machine's serial number and parts manual to confirm the correct application before ordering.
A cap nut is a closed-end fastener that threads onto a bolt or stud, covering the exposed thread end to protect it from contamination, corrosion, and mechanical damage while maintaining clamping force on the assembled joint. On a tandem roller operating under sustained vibration, maintaining correct fastener torque across all hardware points is critical to keeping drum assemblies, frame joints, and panel mounts secure and properly aligned. When a cap nut is damaged, cross-threaded, or missing, the exposed thread is vulnerable to corrosion and the joint can work loose over time, potentially affecting machine performance and structural integrity.
