The Wacker Neuson 111991 Baseplate is a genuine OEM component designed for the WP1540 series single-direction vibratory plate compactors, including the WP1540, WP1540A, WP1540W, and WP1540AW models. As a direct OEM replacement sourced through the Wacker Neuson parts program, part 111991 is manufactured to the same specifications as the original unit it replaces. This baseplate fits across the full WP1540 family, covering standard, wheeled, and wheeled-with-wheel-kit configurations, making it a straightforward swap for operators servicing any variant in this series.
Key Features
- OEM-Grade Structural Integrity — Manufactured to the same material and dimensional tolerances as the original, ensuring the baseplate handles the continuous impact and vibration loads of plate compactor operation.
- Drop-In Compatibility — Engineered to mount directly to the WP1540 exciter housing without modification, using existing hardware and bolt patterns.
- Broad WP1540 Series Coverage — Confirmed fitment across WP1540, WP1540A, WP1540W, and WP1540AW variants, including standard and wheel-kit-equipped configurations.
- Sustained Compaction Performance — A sound baseplate maintains full contact between the plate and compaction surface, preserving force transfer efficiency for consistent soil, aggregate, and paving stone prep results.
- Genuine Wacker Neuson Part — Supplied as genuine OEM under part number 111991, backed by the Wacker Neuson parts program for verified fitment accuracy.
The baseplate is the primary ground-contact component of a vibratory plate compactor. It transmits the eccentric force generated by the exciter unit directly into the surface being compacted — soil, aggregate base, asphalt, or paving stone — and its flat, rigid profile is what allows the machine to deliver uniform compaction across each pass. When the baseplate becomes cracked, warped, or worn through heavy use, force transfer becomes uneven, compaction depth and consistency drop off, and the machine may exhibit increased vibration or erratic tracking. Replacing a damaged baseplate with a genuine OEM unit like the Wacker Neuson 111991 restores the machine to full operating condition and protects the exciter assembly from the stress caused by an uneven or compromised contact surface.
