Multiquip 2106403W00 Fan Spacer

The Multiquip 2106403W00 Fan Spacer is a genuine OEM component designed for C30HDNI and C30HDN series concrete pumps, including C30HDNI Precision and C30HDNI Zenith variants. As a direct factory replacement, this spacer maintains the correct positional alignment of the cooling fan relative to the engine assembly, ensuring proper airflow and thermal management during operation. Sourced from Multiquip, part number 2106403W00 is built to the same specifications as the original component installed at the factory.

Key Features

• Exact OEM Dimensional Tolerance — Manufactured to the original specification, this spacer maintains the precise axial positioning the fan requires for consistent cooling performance.
• Direct Drop-In Replacement — Designed to install in the same location as the original, with matching mounting geometry for the C30HDNI and C30HDN concrete pump cooling system.
• Broad C30HD Family Fitment — Compatible with C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith models, covering multiple engine and fuel system configurations in the C30HD lineup.
• Cooling System Integrity — A correctly positioned fan spacer keeps the fan running true at the right standoff distance, preventing airflow restriction and protecting the engine from heat-related stress during continuous pumping cycles.
• Genuine Multiquip OEM Part — Backed by Multiquip's OEM supply chain, this component meets the same material and manufacturing standards as the part originally fitted to your machine.

A fan spacer sets and maintains the correct lateral position of the cooling fan on the engine shaft, ensuring the fan blades sit at the designed distance from the radiator or shroud. This spacing directly affects airflow volume and direction — if the spacer is worn, cracked, or missing, the fan can shift out of position, reducing cooling efficiency and potentially causing the engine to run hot under load. On a concrete pump like the C30HD series, where the engine works hard during extended pours, maintaining correct fan alignment is essential to keeping operating temperatures within a safe range.
