The Wacker Neuson Tappet is a genuine OEM component designed for the RD27-100 and RD27-120 Hydrostatic Vibratory Rollers. As a direct-source OEM part, the is manufactured to the same standards as the original, ensuring it seats and operates correctly within the valvetrain without rework or adaptation. This tappet is a confirmed fit for both the RD27-100 and RD27-120 roller models, making it a straightforward replacement when servicing the engine on either machine.
Key Features
- Genuine OEM Valvetrain Tolerancing — manufactured to the exact dimensional spec of the original tappet, maintaining correct valve lift and contact geometry within the engine.
- Drop-In Engine Replacement — installs directly into the tappet bore of the RD27-100 and RD27-120 engine without machining or shimming.
- Confirmed Fitment for RD27 Series Rollers — verified for the RD27-100 and RD27-120 Hydrostatic Vibratory Rollers, covering both model variants in the RD27 family.
- Consistent Valve Timing Integrity — a worn or damaged tappet disrupts valve timing and lift, leading to rough running, loss of compression, and accelerated camshaft wear; a correctly fitted tappet keeps the engine operating at spec.
- Fuel and Emission System Compliance — proper tappet function directly affects combustion efficiency; using a correctly sized OEM tappet helps maintain the engine's designed fuel consumption and emissions profile.
A tappet — also called a valve lifter — sits between the camshaft lobe and the valve stem or pushrod inside the engine, transmitting the camshaft's rotational motion into the linear movement needed to open and close each valve. When a tappet wears down or develops surface pitting, valve lift becomes inconsistent, which can cause rough idle, misfiring, reduced power output, and in severe cases, contact damage to the camshaft lobe itself. Replacing a worn tappet promptly with a correctly dimensioned OEM part restores proper valve timing and protects the surrounding valvetrain components on your RD27 roller.
