The Wacker Neuson Upper Mass (WP) is a genuine OEM component designed for the WP1550e and WP1550we reversible plate compactors. Sourced directly from Wacker Neuson, this part carries the same specifications as the original, ensuring it installs and performs exactly as the factory intended. If you are servicing a WP1550e or WP1550we and need a verified, correct-fit upper mass, part is the right choice.
Key Features
- Genuine OEM Mass Assembly Integrity — Manufactured to Wacker Neuson's original weight and dimensional specifications, ensuring the dynamic balance and compaction output of the machine are not compromised.
- Direct Drop-In Replacement — Matches the original mounting points and mass geometry of the WP1550e and WP1550we upper assembly, allowing straightforward installation without modification.
- Confirmed Fitment for WP1550e and WP1550we — Verified against model numbers WP1550e (5100062425) and WP1550we (5100062426) for accurate parts sourcing.
- Preserves Compaction Force and Plate Balance — A correctly weighted upper mass keeps the exciter system operating within its designed force range, maintaining plate output across varying soil conditions.
- Genuine Wacker Neuson Part — Backed by Wacker Neuson's OEM supply chain, so you receive a part that meets the same material and tolerance standards as what left the factory originally.
The upper mass is a critical component of a reversible plate compactor's vibration system. It works in conjunction with the lower exciter assembly to generate and direct the compaction force that drives the plate into the ground. The mass is precisely engineered in terms of weight and geometry — if it is worn, cracked, or incorrectly replaced, the balance of the exciter system is disrupted, which reduces compaction efficiency and places additional stress on the machine's drive and bearing components. Keeping this part in sound condition is essential to maintaining consistent plate performance and protecting the surrounding drivetrain components from premature wear.
