Wacker Neuson 5000070986 Rocker Arm

The Wacker Neuson is a genuine OEM Rocker Arm designed for a wide range of Wacker Neuson equipment powered by compatible small gasoline engines. As a genuine OEM component, it is manufactured to the exact specifications of the original part, ensuring a correct fit and consistent engine performance across every compatible machine. This single part covers an extensive lineup including BFS735 floor saws, CT24-4A and CT36-5A walk-behind concrete trowels, VP and WP series single-direction vibratory plates, BPU reversible vibratory plates, PT2A centrifugal trash pumps, PDT and PDI diaphragm trash pumps, GP and GV portable generators, and several internal vibrator power units. Whether you are servicing a concrete finishing machine, a compaction plate, or a pump, the is the correct Wacker Neuson replacement to restore proper valve train operation.

Key Features

• Exact OEM Valve Train Geometry — Manufactured to Wacker Neuson's original rocker arm profile, preserving the correct valve lift ratio and contact geometry for proper combustion.
• Direct Engine Drop-In — Mounts directly to the rocker arm shaft using the original hardware; no machining or adaptation to the cylinder head required.
• Broad Cross-Equipment Compatibility — A single part number covering BFS735 floor saws, CT-series walk-behind trowels, VP/WP/BPU/BPS vibratory plates, PT2A trash pumps, PDT/PDI diaphragm pumps, GP/GV generators, and internal vibrator power units.
• Restores Full Engine Power Output — A worn or damaged rocker arm causes valve timing errors, loss of compression, rough running, and hard starting; replacing it returns the engine to its rated power and smooth idle.
• Fuel System and Emission Compliance — Correct valve actuation ensures the air-fuel mixture is drawn and exhausted at the engineered timing, keeping the engine within its designed emission and fuel efficiency parameters.

The rocker arm is a pivoting lever in the engine's valve train that transfers motion from the camshaft — via the pushrod — to open and close the intake and exhaust valves. It acts as a mechanical link that amplifies and redirects camshaft lobe movement so the valves open at precisely the right moment and to the correct lift height. When a rocker arm wears at its contact pad, cracks, or loses its pivot bushing, valve timing becomes erratic, compression drops, and the engine will run rough, lose power, or fail to start. On equipment such as floor saws, concrete trowels, vibratory plates, and pumps — where consistent engine output directly affects work quality and machine control — a failed rocker arm will quickly halt productivity and can lead to further valve train damage if left unaddressed.
