The Wacker Neuson Rocker Arm is a genuine OEM component designed for the RD12-90 double drum roller and CRT36-25 ride-on trowel series. Sourced directly from Wacker Neuson, this part meets the same exacting standards as the original, ensuring a straight swap into your machine without guesswork. It is confirmed compatible with the RD12-90 with solid ROPS and foldable ROPS configurations, as well as the CRT36-25 in standard, wheel kit, and CRT36-26A-WK variants.
Key Features
- Genuine OEM Valve Train Precision — Manufactured to Wacker Neuson's original tolerances, maintaining correct valve timing and consistent lobe-to-valve contact that an aftermarket approximation may not replicate.
- Drop-In Replacement — Engineered to mount directly onto the original rocker shaft and seat against the existing valve stem and pushrod without shimming or reworking the head.
- Broad Model Coverage — Fits the RD12-90 tandem roller (solid and foldable ROPS) and the CRT36-25 ride-on trowel family, including wheel kit and CRT36-26A-WK configurations.
- Protects Engine Valve Operation — A correctly functioning rocker arm transfers camshaft motion accurately to the intake and exhaust valves; a worn or cracked rocker causes misfires, power loss, and potential valve damage.
- Genuine Part Number Traceability — Part number 5000215243 is the active Wacker Neuson OEM reference, making reordering and service record documentation straightforward.
The rocker arm sits at the heart of the engine's valve train, acting as a pivot-driven lever that converts the upward push of the pushrod — driven by the camshaft — into the downward motion needed to open the intake and exhaust valves at precisely the right moment. Without correct rocker arm geometry and surface integrity, valve timing drifts, combustion efficiency drops, and the engine can develop a pronounced tapping or knocking noise. If a rocker arm is worn, cracked, or has a damaged contact pad, the result is poor engine performance, increased fuel consumption, and — if left unaddressed — accelerated wear to the valve stem and camshaft lobe.
