The Multiquip 50866 is a genuine OEM Hydraulic Oil Element designed for PRO12, PRO20, WBH-16, WBH-21, and AR13/AR14 series equipment. As a direct OEM replacement sourced through Multiquip's authorized parts network, this element meets the exact specifications of the original component. Compatible models include Essick stationary mixers (PRO12, PRO12E51, PRO12E53, PRO20), Whiteman hydraulic power buggies (WBH-16, WBH-16E, WBH-16EAWD, WBH-16EAWDF, WBH-16EF, WBH-16F, WBH-21EF, WBH-21EFP, WBH21EPA), and AR-series ride-on rollers (AR13D, AR13H, AR13HA/HAR, AR13HC, AR14H). Installing the correct OEM-grade filter element is one of the simplest ways to protect your hydraulic system and keep these machines performing at full capacity.
Key Features
- OEM Filtration Integrity — Engineered to the same micron rating and flow capacity as the original element, ensuring consistent contamination control in the hydraulic circuit.
- Drop-In Replacement — Matches the original housing interface and bypass valve configuration for straightforward filter service with standard tools.
- Broad Fitment Coverage — Confirmed for PRO12, PRO20, WBH-16, WBH-21, and AR13/AR14 series models across Essick mixer, Whiteman power buggy, and asphalt roller applications.
- Hydraulic System Protection — A fresh, properly rated element removes particulate and wear debris that would otherwise circulate through pumps, motors, and valves, extending component service life.
- Genuine OEM Part — Supplied under Multiquip part number 50866, providing confident traceability and correct specification compliance for fleet maintenance records.
The hydraulic oil element is a filter component installed in the hydraulic return or pressure circuit of equipment that relies on hydraulic power to drive functions such as drum mixing, wheel drive, or blade actuation. Its job is to trap particulate contamination — metal wear particles, dirt, and degraded fluid byproducts — before they can reach sensitive hydraulic components like pumps, control valves, and motors. When this element becomes clogged or is left in service past its change interval, flow restriction increases, system pressure drops, and unfiltered fluid can bypass the element entirely, accelerating wear and risking costly component failure across the entire hydraulic circuit.
