Multiquip EM98228 Coil WA 704107-12

The Multiquip EM98228 Coil WA 704107-12 is a genuine OEM solenoid coil designed for Mayco concrete pump models including C30HDZ, LS600P, LS600, LS50TD, LS40TD, LS500, LS400, LS40D, and LS60TD. Sourced directly from Multiquip, this coil delivers the correct electrical specification needed to maintain precise hydraulic valve control across the full range of compatible LS and C-series concrete pumps. Choosing the OEM part means you get an exact match to the original component — no guesswork on fitment or output rating. DHS Equipment stocks this part to help keep your Mayco pump running to its original operating specification.

Key Features

• Correct Electrical Output Rating — Wound to the original voltage and inductance specification, ensuring the solenoid valve actuates fully and consistently under hydraulic load.
• Genuine OEM Component — Sourced directly from Multiquip, this coil meets the same production standard as the unit installed at the factory on compatible Mayco pump models.
• Broad Mayco Pump Compatibility — Confirmed fit across the C30HDZ, LS400, LS500, LS600, LS600P, LS40D, LS40TD, LS50TD, and LS60TD concrete pump models.
• Direct Hydraulic Valve Control — Engineered to interface directly with the hydraulic control valve assembly on compatible pumps; installs in the same position as the original coil without modification to the valve body.
• Prevents Pumping Cycle Failures — A worn or failed solenoid coil causes erratic valve switching or complete loss of hydraulic actuation; replacing with EM98228 restores consistent, uninterrupted pump cycling.

A solenoid coil is an electromagnetic component that controls the opening and closing of a hydraulic directional control valve. When electrical current passes through the coil, it generates a magnetic field that shifts the valve spool, directing hydraulic fluid to drive the pumping cylinders. On Mayco concrete pumps like the LS and C-series models, this action controls the entire pumping stroke cycle. When the coil degrades — through heat exposure, moisture ingress, or winding failure — the valve loses the ability to shift reliably, resulting in weak output, erratic cycling, or a pump that stops delivering concrete altogether. Replacing a faulty coil with the correct OEM unit restores full hydraulic responsiveness and gets the pump back to rated output.
