The Wacker Neuson Tappet is a genuine OEM component designed for the LTN4Y and LTN5Y series light towers, including LTN4Y, LTN4Y RH, LTN4Y SA, LTN4Y 60Hz, LTN4Y 120V/60Hz, LTN5Y, LTN5Y CH, LTN5Y UK, LTN5Y SA, LTN5Yp, LTN5Yp HD, LTN5Ypa, and LTN5Ypk models. Sourced directly from Wacker Neuson, this genuine OEM part is manufactured to the same specification as the original, ensuring a direct, trouble-free installation. With broad compatibility across the LTN4Y and LTN5Y light tower families, the is the correct part to specify when servicing these machines. Keep this part on hand to avoid extended downtime during scheduled valve train maintenance.
Key Features
- Genuine OEM Valve Train Precision — Manufactured by Wacker Neuson to the original profile and hardness spec, maintaining correct valve actuation and lift geometry in the engine.
- Direct Drop-In Installation — Seats into the engine block the same way as the factory part, with no fitting, grinding, or adaptation needed during a valve train service.
- Wide LTN Series Compatibility — Fits the full LTN4Y and LTN5Y light tower families, including SA, RH, CH, UK, 60Hz, 120V/60Hz, HD, pk, and pa variants.
- Consistent Valve Timing — A correctly profiled tappet maintains accurate valve open/close timing, supporting smooth engine operation and efficient fuel combustion in the field.
- Correct Part for Scheduled Service — Tappets are wear items inspected and replaced during valve train service intervals; using the correct OEM part keeps clearances within spec after adjustment.
A tappet — also called a valve lifter — sits between the camshaft and the valve stem (or pushrod) inside the engine, transferring the rotating motion of the cam lobe into the linear motion that opens and closes each intake and exhaust valve. As the camshaft rotates, the tappet rides against the lobe and pushes the valve open at precisely the right moment in the combustion cycle. Over time, the contact face of a tappet wears down, which changes valve clearances, reduces lift, and can cause rough running, loss of power, or increased fuel consumption in the engine powering the light tower. Replacing a worn tappet with the correct Wacker Neuson OEM part restores proper valve timing and helps the engine run cleanly at rated output.
