The Wacker Neuson Valve Spring is a genuine OEM component designed for the DPU6555Heh, DPU6555Hech, and DPU6555 Vibration Plate series compactors. Sourced directly from Wacker Neuson, this part meets the exact specifications required for proper engine valve operation on these machines. Fitment covers the DPU6555Heh US, DPU6555Hech US, and associated Vibration Plate variants, so you can order with confidence knowing this is the correct spring for your machine.
Key Features
- Genuine OEM Spring Tension Spec — Manufactured to the exact load and free-length specification required for correct valve timing and seating in DPU6555-series engines.
- Drop-In Engine Replacement — Engineered to seat directly onto the valve stem retainer assembly with no reworking of surrounding components.
- Confirmed Fitment — Compatible with DPU6555Heh US, DPU6555Hech US, and DPU6555 Vibration Plate models; cross-reference part number 5100062279 before ordering.
- Consistent Valve Closure Force — A correctly tensioned valve spring keeps intake and exhaust valves closing fully at speed, maintaining compression and preventing power loss or rough running.
- Fuel System Integrity — A fatigued or broken valve spring can allow valve float at operating RPM, leading to incomplete combustion, increased fuel consumption, and potential engine damage — replacing it promptly protects the wider engine assembly.
A valve spring holds each engine valve firmly closed against its seat when not actuated by the camshaft. It provides the return force that snaps the valve shut after each cycle, ensuring a proper compression seal in the combustion chamber. When a valve spring weakens or breaks, the valve may not seat fully, causing a loss of compression, erratic idling, reduced power output, and accelerated wear on valve seats and guides.
