Multiquip EM918050 Clutch Spring

The Multiquip EM918050 Clutch Spring is a genuine OEM component designed for Mayco C30HD, C30HDNI, and C30HDN series concrete pumps. As a direct OEM replacement, this spring is sourced to the original specification, ensuring correct tension and engagement behavior in the clutch assembly. Confirmed fitment covers the C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, and C30HDN models. When you need to restore reliable clutch operation, matching the original part number EM918050 is the safest path.

Key Features

• Correct Spring Rate: — Engineered to the original tension specification, so the clutch engages and releases with the force the system was designed around — not an approximation.
• Genuine OEM Sourcing: — Produced to Multiquip's original standards for the Mayco concrete pump clutch assembly, maintaining the integrity of the drivetrain.
• Broad Mayco C30 Compatibility: — Fits C30HD, C30HDNI, C30HDNI Precision, C30HDNI Zenith, and C30HDN — covering the full C30 family in a single part number.
• Direct Drop-In Installation: — Matches the original mounting geometry of the clutch assembly, seating correctly without rework or modification to surrounding components.
• Protects Clutch Longevity: — A correctly tensioned spring prevents clutch slip and premature wear on the friction surfaces, extending the service life of the broader clutch assembly.

The clutch spring in a Mayco concrete pump provides the return tension that controls clutch engagement and disengagement within the drivetrain. It maintains the correct clamping force between clutch components, allowing the operator to transfer power from the engine to the pump smoothly and consistently. When this spring weakens, loses tension, or breaks, the clutch may slip under load, fail to fully disengage, or engage erratically — disrupting pumping output and accelerating wear on surrounding clutch parts. Replacing a fatigued or failed clutch spring promptly with the correct OEM part restores predictable clutch behavior and protects the broader assembly.
