The Wacker Neuson 5100013801 is a genuine OEM Check Disc Complete designed for the DPU4545, DPU5545, and DPU6555 series reversible vibratory plate compactors. As a factory-original component, it is manufactured to the exact specifications required by these heavy-duty diesel-powered machines. Fitment covers multiple configurations across the DPU4545Heh, DPU4545Hech, DPU5545Heh, DPU5545Hech, DPU6555He, DPU6555Heh, DPU6555Hec, and DPU6555Hech US models. Sourcing the correct OEM part by part number 5100013801 ensures a direct, application-matched installation.
Key Features
- Factory-Original Disc Geometry — Manufactured to the precise tolerances required for correct valve action in Wacker Neuson DPU-series hydraulic exciter systems.
- Direct Drop-In Installation — Engineered to seat exactly as the original, maintaining proper sealing contact and alignment within the hydraulic circuit without rework.
- Broad DPU Series Compatibility — Fits DPU4545, DPU5545, and DPU6555 models across both standard and combination (Heh/Hech/Hec) configurations sold in the US market.
- Preserves Compaction Force and Direction Control — A correctly functioning check disc maintains consistent hydraulic pressure regulation, enabling the plate to deliver full compaction output and responsive forward/reverse travel.
- Hydraulic System Integrity — A worn or failed check disc can allow backflow within the exciter circuit, leading to erratic compaction behavior, loss of reverse function, or internal hydraulic damage; replacing it promptly protects downstream components.
The check disc is a critical one-way flow control component seated within the hydraulic exciter unit of a reversible vibratory plate compactor. It prevents hydraulic fluid from flowing backward through the circuit, which is what allows the operator to switch the direction of plate travel and maintain consistent centrifugal force during compaction passes. When the check disc wears, cracks, or loses its seating, the hydraulic system can no longer hold proper pressure differential — resulting in weak compaction, loss of directional response, or fluid bypass that stresses the exciter pump and motor over time.
