Key Features

• Genuine OEM Drivetrain Integrity — Manufactured to original Multiquip specifications, maintaining the correct torque transfer and shaft geometry critical for concrete pump operation.
• Direct Drop-In Replacement — Machined to match original dimensions and mounting interfaces, so installation aligns with existing housings and bearings without rework.
• Broad C30HD Series Fitment — Compatible with C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDN, C30HDG, C30HDGA, and C30HDZ concrete pump models.
• Sustained Power Transmission — A correctly functioning counter shaft maintains consistent drive between the engine and pump mechanism; a worn or damaged shaft leads to erratic output pressure and accelerated wear on adjacent components.
• Authentic Multiquip Sourcing — Sold by DHS Equipment as an authorized Multiquip OEM part, giving you traceability and confidence in part authenticity for high-demand concrete pumping applications.

The counter shaft is a core drivetrain component within the concrete pump's power transmission system. It receives rotational force from the engine and transfers it to the pump mechanism, acting as an intermediate shaft that allows the correct speed and torque ratio to be delivered to the pumping assembly. When the counter shaft wears, cracks, or fails, the pump loses its ability to move concrete consistently — resulting in pressure loss, irregular output, or complete drivetrain failure. Replacing a damaged counter shaft promptly with a genuine OEM part like the EM513073 restores proper mechanical function and protects surrounding drivetrain components from secondary damage.
