Bumper | 30x15-55SH, Form D | WP1540, WP1550

The Wacker Neuson 88873 Shockmount is a genuine OEM component designed for CRT48 series ride-on concrete trowels and WP / WPP / WPU series single-direction vibratory plate compactors. Sourced directly from Wacker Neuson, part 88873 matches the original specification for a direct, hardware-compatible installation. Confirmed fitment spans the CRT48-33K, CRT48-34V, CRT48-35L, CRT48-35V, CRT48-37V, and CRT48-57K trowel families, as well as WP1030, WP1235, WP1540, WP1550, WP2050, and WPP / WPU 1550 vibratory plate models. When your original shockmount shows signs of cracking, compression loss, or excess vibration transfer, replacing it with the correct OEM part restores proper isolation and protects surrounding components.

Key Features

• OEM Compression and Material Grade — Manufactured to Wacker Neuson's original rubber compound and durometer specification, ensuring the correct deflection range for vibration isolation in both trowel and plate compactor applications.
• Drop-In Mounting Compatibility — Retains the original bolt pattern and mounting geometry, allowing installation without drilling, slotting, or adapting the mounting surface.
• Broad Fitment Across Two Machine Families — A single part number covers CRT48 ride-on trowel variants and the WP / WPP / WPU vibratory plate range from WP1030 through WP2050, simplifying stock management on mixed fleets.
• Protects Adjacent Components — A fully functional shockmount absorbs and dampens operating vibration before it reaches the frame, handles, and engine mounts; a degraded mount allows metal-to-metal contact that accelerates wear across multiple assemblies.
• Genuine OEM Traceability — Supplied as an authentic Wacker Neuson replacement, carrying the same part number 88873 used in the original build, making verification against the machine's parts manual straightforward.

A shockmount is a rubber-bonded isolator that sits between a vibrating component or subassembly and the machine's main frame or handle structure. Its job is to absorb and attenuate the high-frequency vibration generated during compaction or troweling, preventing that energy from transmitting directly into the operator or into rigid structural components. Over time, the rubber element degrades through heat cycling, UV exposure, and repeated compression, eventually cracking or losing its elastic recovery — at which point vibration transfer increases sharply, operator fatigue rises, and surrounding bolted connections are subjected to stress they were not designed to handle. Replacing a worn shockmount promptly keeps the machine operating within its intended vibration profile and maintains operator comfort and component longevity.
