Wacker Neuson 5000156460 Rocker Box Gasket

The Wacker Neuson is a genuine OEM Rocker Box Gasket designed for a wide range of Wacker Neuson equipment, including CT36 and CT48 concrete trowels, GP2600 and GP4000 portable generators, PT2 and PT3 centrifugal trash pumps, PDT and PG series diaphragm and dewatering pumps, and VP and WP series single-direction vibratory plates. As a factory-sourced component, the is manufactured to the exact material and dimensional specifications of the original part, ensuring a correct seal every time. This gasket is a direct fit across an extensive range of Wacker Neuson engine-powered equipment built around the same engine platform. Keep a spare on hand — rocker box gaskets are a routine service item that should be replaced any time the valve cover is removed or oil seepage is detected at the rocker cover joint.

Key Features

• OEM-Grade Sealing Material — Manufactured from the same gasket compound used in original production, providing consistent compression and oil-tight sealing at the rocker cover interface.
• Drop-In Engine Fit — Matches the bolt pattern and profile of the rocker box cover exactly, so it seats flush without trimming or reshaping during reinstallation.
• Broad Cross-Family Compatibility — A single gasket part number covers CT36 and CT48 trowels, GP2600/GP4000 generators, PT2/PT3 trash pumps, PDT/PG diaphragm and dewatering pumps, and VP/WP vibratory plate compactors sharing the same engine.
• Prevents Oil Loss at the Valve Cover — A failed or crushed rocker box gasket allows engine oil to seep past the cover joint, leading to oil consumption, contamination of surrounding components, and potential engine damage if left unchecked.
• Genuine Wacker Neuson OEM Part — Sourced directly through authorized Wacker Neuson supply channels under part number 5000156460, so you can verify fitment against your machine's serial number before ordering.

The rocker box gasket — also called a valve cover gasket — seals the joint between the rocker arm cover and the engine cylinder head, keeping oil inside the valvetrain as it lubricates the rocker arms and valve stems. Without a properly sealing gasket, engine oil migrates out of the valvetrain cavity, leaving oily residue on the engine exterior and potentially dripping onto hot surfaces or work areas. Over time, a leaking or brittle rocker box gasket can cause oil levels to drop unnoticed, increasing wear on internal engine components. Replacing this gasket during any valve cover service is considered standard practice and restores a clean, reliable seal to the top end of the engine.
