The Multiquip EM507713 Idler Arm is a genuine OEM component designed for Essick and Whiteman plaster and mortar mixer models, including the EM70P/S and WM70S/P series. As a direct OEM replacement, this part is produced to the same specifications as the original, ensuring a consistent fit within the mixer's belt and drive system. Sourced through authorized Multiquip supply channels, the EM507713 is the correct-spec part for these mixer families and is available through DHS Equipment. Verify your model code against the fitment list before ordering to confirm compatibility.
Key Features
- OEM-Grade Construction — Manufactured to original Multiquip tolerances, delivering the same structural integrity and dimensional accuracy as the part that came on the machine.
- Direct Drop-In Replacement — Mounts in the factory pivot position with no reworking of surrounding brackets or hardware required.
- Confirmed Fitment — Compatible with Essick EM70P/S and Whiteman WM70S/P plaster and mortar mixers.
- Drive System Stability — A correctly tensioned idler arm keeps the belt tracking true under load, maintaining consistent drum rotation and mixing output throughout the pour.
- Wear-Failure Prevention — A worn or seized idler arm causes belt slippage, uneven drum speed, and accelerated belt wear — replacing it at first sign of play keeps the drivetrain operating as intended.
The idler arm is a pivoting bracket within the mixer's belt drive system, responsible for maintaining proper belt tension against the drive and driven pulleys. By holding the belt at the correct tension, it ensures torque is transferred efficiently from the engine to the mixing drum without slip or vibration. When the idler arm wears at its pivot, becomes bent, or seizes, belt tension is lost — leading to reduced drum speed, belt wear, and in severe cases, complete loss of drum rotation during mixing operations.
