The Multiquip EM402996 Spacer is a genuine OEM component designed for C30HD, C30HDNI, C30HDG, C30HDZ, C30HDGA, and C30HDN series concrete pumps. As a factory-sourced replacement, EM402996 is manufactured to the same tolerances as the original part, ensuring correct positioning and clearance within the pump assembly. This spacer is a direct-fit replacement for Mayco concrete pump models in the C30HD family, covering variants including C30HDNI Precision and C30HDNI Zenith configurations.
Key Features
- Genuine OEM Tolerancing — Manufactured to exact dimensional specifications, ensuring correct load distribution and component spacing within the pump drivetrain.
- Drop-In Replacement — Matches the original mounting interface on C30HD-series concrete pumps, installing in place of the factory part without modification.
- Broad C30HD Family Coverage — Fits C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDN, C30HDG, C30HDZ, and C30HDGA pump models.
- Maintains Internal Alignment — A correctly fitted spacer keeps adjacent components properly separated and aligned; a worn or missing spacer can cause uneven wear, misalignment, and accelerated damage to surrounding parts.
- Sourced Direct from Multiquip — Supplied as a genuine Multiquip part, so you receive the same component used in original production rather than an approximation.
A spacer is a precision-dimensioned component used to maintain a fixed gap or positional relationship between two adjacent parts within an assembly. In a concrete pump, spacers are commonly used in drivetrain, shaft, and mechanical linkage assemblies to control bearing preload, prevent metal-to-metal contact, and ensure that rotating or reciprocating components operate within their intended range of motion. When a spacer wears down, becomes damaged, or goes missing, surrounding components lose their reference position — leading to accelerated wear, vibration, or mechanical failure in the assemblies it supports.
