The Multiquip EM18806 Insert Wear 5 1/2 x 5 C30HD is a genuine OEM wear insert designed for the C30HD concrete pump. Sourced directly from Multiquip, this part meets the original dimensional and material specifications required to keep your pump cycling accurately and efficiently. It is a direct-fit replacement confirmed for C30HD Mayco concrete pump applications.
Key Features
- OEM-Grade Wear Resistance — Manufactured to the original material hardness and dimensional tolerances required for concrete pump wear inserts, where abrasion resistance directly determines service life.
- Exact Dimensional Fit — The 5 1/2 x 5 specification matches the original bore and seat geometry of the C30HD pump housing, ensuring the insert seats correctly without rework or shimming.
- Confirmed C30HD Compatibility — Verified for Mayco C30HD concrete pump models, so you can order with confidence that this insert matches your machine's pump cylinder assembly.
- Restored Pump Output — A worn or undersized wear insert allows slippage and pressure loss in the pump cylinder; replacing it with this part restores consistent concrete displacement and output pressure.
- Genuine Multiquip OEM Part — As a factory-authorized component, this part is produced to the same standards as the original part installed at the factory, with no substitution in alloy grade or geometry.
A wear insert in a concrete pump lines the cylinder bore and provides the sacrificial hardened surface against which the piston or valve operates under high-pressure cycling. Because concrete is highly abrasive, this insert absorbs the majority of wear so the surrounding pump housing is protected. As the insert wears down, clearance between the piston and the bore increases, causing a loss of pumping pressure, inconsistent output, and eventual bypass of material. Replacing the wear insert at the correct service interval is one of the most direct ways to maintain full pump performance and extend the life of the surrounding cylinder components.
