The Wacker Neuson Engine Valves Spring is a genuine OEM component designed for DS70 and DS720 diesel vibratory rammers, as well as select diesel vibratory plate compactors including the VPY1740, VPY1750, VP2050Y, DPU 2950Y, and DPS1850Y series. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory. Correct fitment is confirmed across multiple DS70 and DS720 configurations, including 280mm/11in and 330mm/13in shoe variants, making it a straightforward drop-in replacement for machines already in the field.

Key Features

  • Genuine OEM Valve Spring Specification — Manufactured to exact tension and free-length tolerances required for proper valve train operation in Wacker Neuson diesel engines.
  • Direct Drop-In Replacement — Seats and retains using the original valve spring retainer hardware, requiring no machining or additional modification to the cylinder head.
  • Broad Diesel Rammer and Plate Fitment — Compatible with DS70 and DS720 diesel vibratory rammers and multiple diesel vibratory plate models including the VPY1740, VPY1750, VP2050Y, DPU 2950Y, and DPS1850Y.
  • Consistent Valve Seating Pressure — Maintains the correct closing force on intake and exhaust valves, supporting proper compression and combustion efficiency across the engine's operating range.
  • Engine Safety Relevance — A fatigued or broken valve spring can cause valve float, loss of compression, or catastrophic valve contact with the piston — replacing at the first sign of wear protects the engine from further internal damage.

A valve spring holds each intake and exhaust valve firmly closed against its seat when the valve is not being actuated by the camshaft. By maintaining consistent seating pressure, it ensures the combustion chamber seals correctly on every cycle, preserving compression and preventing exhaust gases from escaping at the wrong time. When a valve spring weakens from fatigue or breaks entirely, the affected valve may not close fully, leading to misfiring, hard starting, loss of power, or — in severe cases — the valve dropping into the combustion chamber and causing major internal engine damage.
