The Wacker Neuson Tappet is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory rollers, including standard and traction control configurations. As a direct OEM replacement, part is manufactured to the exact tolerances required for correct valve train operation in these machines. Compatible across multiple build variants of the RD27 family, this tappet slots in as a direct replacement with no guesswork on fitment. Keep your roller running at spec — verify your machine number before ordering to confirm compatibility.
Key Features
- Genuine OEM Precision — Manufactured to exact dimensional tolerances for consistent valve lift and controlled contact with the camshaft lobe, preventing premature wear in the valve train.
- Direct Drop-In Replacement — Engineered to the same profile and seat geometry as the original, seating correctly into the tappet bore without rework or adjustment.
- Broad RD27 Family Coverage — Fits RD27-100 and RD27-120 hydrostatic vibratory rollers across standard and traction control variants, spanning multiple serial number ranges.
- Restored Engine Performance — A worn or collapsed tappet causes inconsistent valve timing, rough running, and power loss; replacing it with 5000161364 restores smooth, consistent engine output.
- Engine Protection — Correct tappet clearance is critical to preventing valve damage and cylinder head wear — using a properly spec'd OEM tappet safeguards the entire valve train assembly.
A tappet — also called a valve lifter — sits between the camshaft and the valve stem (or pushrod) inside the engine, transferring the rotational motion of the camshaft into the up-and-down motion that opens and closes the engine's valves. Maintaining the correct tappet clearance ensures each valve opens fully and closes completely at the right moment in the combustion cycle, directly affecting engine power, fuel efficiency, and smooth operation. When a tappet wears down or fails, valve timing becomes erratic, leading to symptoms such as a ticking noise from the valve train, loss of compression, rough idle, or reduced power output — all of which put added stress on surrounding engine components if left unaddressed.
