The Wacker Neuson Knob is a genuine OEM component designed for the RD12A-90 tandem roller series, GS12Ai, CRT36-26A and CRTv36-26A trowel series, and GPS9700A. Sourced directly from Wacker Neuson, this replacement knob matches the original part exactly — same materials, same dimensions, same fit as the knob your machine left the factory with. It is confirmed compatible across multiple RD12A-90 configurations including standard, foldable ROPS, and double drum variants, as well as wheel kit and standard trowel builds in the CRT36-26A and CRTv36-26A lines.
Key Features
- OEM-Matched Construction — Manufactured to Wacker Neuson's original material and dimensional specification, so the knob operates with the same tactile response and durability as the part it replaces.
- Direct Drop-In Replacement — Engineered to seat and secure identically to the original, with no rework needed to mounting threads or mating surfaces.
- Broad Model Coverage — Fits the RD12A-90 roller series, GS12Ai, CRT36-26A and CRTv36-26A trowel series (including wheel kit variants), and the GPS9700A — confirmed by Wacker Neuson part fitment data.
- Smooth, Positive Operator Control — A worn or damaged knob makes precise control adjustments difficult; a correctly fitted knob keeps operator inputs accurate and responsive during compaction and finishing work.
- Genuine OEM Part — Part number 5000226487 is an authorized Wacker Neuson replacement, giving you confidence that the part is correct before it ships.
A knob provides the operator with a secure, ergonomic grip point for adjusting a control, lever, or dial on the machine. On compaction and finishing equipment, knobs are used to set operational parameters or lock settings in place during use — making a firm, intact knob essential for consistent machine control. When a knob cracks, strips, or breaks away, precise adjustment becomes unreliable, which can affect output quality and slow down the work.
