The Multiquip 655 Isolator 32 X32 M8-1.25 is a genuine OEM vibration isolator designed for the C30HDG concrete pump. Sourced directly from Multiquip, this part matches the exact geometry, thread spec (M8-1.25), and durometer rating required by the original design — no guesswork on sizing or fitment. If you're servicing a C30HDG and need to restore proper isolation between components, the 655 is the correct replacement to reach for.
Key Features
- OEM-Grade Elastomer Construction — Manufactured to the same compression and deflection characteristics as the original, ensuring the isolator absorbs vibration load correctly across the full operating cycle of the pump.
- Exact Thread and Dimensional Match — 32 x 32 mm body with M8-1.25 thread pitch installs directly into the existing mounting points on C30HDG concrete pumps without rework or adapters.
- Confirmed Fitment for C30HDG — Verified genuine OEM replacement for the Mayco C30HDG cycloidal-drive concrete pump series.
- Protects Surrounding Components — A correctly functioning isolator cushions pump vibration before it transfers to the frame, preventing premature wear on fasteners, brackets, and adjacent assemblies.
- Genuine Multiquip OEM Part — Supplied as original equipment, not an approximation — part number 655 matches Multiquip's own parts catalog for this application.
A vibration isolator acts as a buffer between two joined components, absorbing and dampening mechanical vibration generated during pump operation so it does not travel through the machine's frame or housing. On a concrete pump like the C30HDG, isolators play a critical role in keeping the drivetrain and structural components free from resonance-induced fatigue. When an isolator deteriorates — cracking, compressing permanently, or losing its elasticity — vibration transfers unchecked, which accelerates wear on surrounding hardware and can lead to noise, loosening fasteners, and structural stress over time.
