The Wacker Neuson is a genuine OEM Exhaust Rocker Arm designed for a wide range of Wacker Neuson equipment, including PT2 and PT3 centrifugal trash pumps, VP1340, VP1550, and VP2050 series single-direction vibratory plates, WP and WPP series vibratory plates, and CT36-6 walk-behind concrete trowels. As a factory-sourced component, the is manufactured to the exact specifications required by the engine assemblies found across these machine families. Drop it in with confidence — this part matches the geometry, material, and tolerancing of the original. If your machine is showing signs of valve train wear, this is the part to have on hand.
Key Features
- Genuine OEM Valve Train Precision — Manufactured to Wacker Neuson's exact tolerances for correct rocker-to-valve contact geometry, ensuring proper valve lift and timing across the exhaust cycle.
- Direct Engine Replacement — Engineered to seat and align in the original rocker arm bore without modification, maintaining the correct pivot and contact relationship with the pushrod and valve stem.
- Broad Equipment Compatibility — A single part number covering PT2 and PT3 trash pumps, VP1340/VP1550/VP2050 and WP/WPP vibratory plate families, and CT36-6 concrete trowels — check your model before ordering.
- Exhaust Flow Integrity — A correctly functioning exhaust rocker arm ensures full valve travel on every combustion cycle; a worn or seized rocker reduces power output and can cause rough running or hard starts.
- Engine Longevity Protection — Using the OEM part preserves proper valve clearance, preventing accelerated wear on the camshaft lobe, pushrod, and valve seat that an out-of-spec replacement would cause.
The exhaust rocker arm is a pivoting lever in the engine's valve train that transfers motion from the camshaft — via the pushrod — to open the exhaust valve at the correct point in the combustion cycle. It acts as a mechanical linkage between the rotating camshaft and the linearly moving valve, amplifying and redirecting that motion with precision timing. When the rocker arm wears, cracks, or seizes at its pivot, exhaust gases cannot escape the cylinder efficiently, leading to power loss, overheating, and potential damage to surrounding valve train components.
