Multiquip 51117 Drum and Shaft Assembly Hydraulic

The Multiquip 51117 Drum and Shaft Assembly Hydraulic is a genuine OEM component designed for Whiteman Mixers (WM120SH, WM120PH), Essick Mixers (EM120S Series, EM120P Series), and RAMMAX Rollers (RW3010, RW1810). As a direct factory replacement, this assembly maintains the exact dimensional and hydraulic specifications required by these machines, ensuring the drum operates as intended from the moment it is installed. DHS Equipment supplies this part directly as an authorized Multiquip dealer, so you can order with confidence knowing you are receiving the correct OEM assembly.

Key Features

• Genuine OEM Hydraulic Integrity — Manufactured to Multiquip's hydraulic tolerances, ensuring proper fluid engagement and consistent drum rotation under load.
• Direct-Fit Assembly — The shaft and drum are pre-matched as a complete unit, mounting directly to OEM interfaces on compatible Whiteman and Essick mixer models without modification.
• Broad Model Coverage — Fits WM120SH, WM120PH, EM120S Series, EM120P Series, RW3010, and RW1810, covering a wide range of Multiquip mixing and roller equipment.
• Sustained Mixing Performance — A worn or damaged drum and shaft assembly causes irregular drum rotation, inefficient mixing, and increased stress on the hydraulic drive system; this OEM replacement restores full output capacity.
• Hydraulic System Protection — Correct shaft alignment prevents internal hydraulic leakage and undue pressure spikes that can damage downstream drive components over time.

The drum and shaft assembly is the mechanical core of a hydraulically driven mixer drum, transferring rotational force from the hydraulic motor to the mixing drum itself. The shaft must maintain precise alignment within its housing to ensure smooth, consistent drum rotation and efficient material turnover inside the drum. When the shaft wears, bends, or the assembly develops play, the drum loses consistent rotational speed, mixing quality deteriorates, and the hydraulic drive system is placed under abnormal stress — ultimately shortening the service life of surrounding components.
