Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Multiquip's exact bore and outer diameter tolerances, ensuring correct load distribution and shaft alignment within the pump assembly.
- Drop-In Replacement — Matches the original mounting interface of the C30HD family, allowing straightforward installation without machining or fitting adjustments.
- Broad C30HD Series Fitment — Compatible with C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDN, C30HDG, C30HDZ, and C30HDGA concrete pumps.
- Protects Mating Components — A correctly sized bushing reduces wear on surrounding shafts and housings; a worn or oversized bushing accelerates play in the assembly, leading to costly secondary damage.
- Part Number Confidence — EM20814 is the current Multiquip OEM part number for this application — verify against your service manual before ordering to confirm the correct fit for your serial range.
A bushing is a cylindrical sleeve that sits between two moving or mating components — typically a rotating shaft and its housing — to control clearance, reduce friction, and absorb operational loads. In a concrete pump like the C30HD series, bushings support the mechanical components that drive the pumping action, keeping movement smooth and predictable under the continuous stress of pumping abrasive material. When a bushing wears beyond spec, excess play develops between parts, causing accelerated wear on shafts, housings, and seals, and eventually leading to misalignment or mechanical failure if left unaddressed.
