Multiquip 144003 Hydraulic Oil Reservoir

The Multiquip 144003 Hydraulic Oil Reservoir is a genuine OEM component designed for the SP Series MQ Pavement Saws, including models SP303520, SP303526, SP605730, SP605736, SP303516, SP303530. As a direct OEM replacement, this reservoir is built to the same specifications as the original unit, ensuring a correct fit within the hydraulic system of your saw. DHS Equipment sources this part directly through authorized Multiquip supply channels, so you can trust you are receiving an authentic component with the correct part number 144003.

Key Features

• Genuine OEM Construction — Manufactured to original Multiquip specifications, ensuring the reservoir walls, fittings, and capacity match the hydraulic system demands of SP Series pavement saws exactly.
• Direct-Fit Replacement — Designed to drop into the existing mounting position on compatible SP Series models, with original connection points intact for a clean, straightforward swap.
• Broad SP Series Compatibility — Confirmed fitment across SP303516, SP303520, SP303526, SP303530, SP605716, SP605720, SP605726, SP605730, and SP605736 MQ Pavement Saws.
• Hydraulic System Integrity — A properly functioning reservoir maintains correct fluid volume and pressure for the saw's hydraulic circuit, supporting consistent blade depth control and drive system response.
• Leak-Resistant Design — OEM construction means sealing surfaces and fittings are dimensionally accurate, reducing the risk of fluid loss that can starve hydraulic components and cause premature wear.

The hydraulic oil reservoir stores and supplies hydraulic fluid to the pavement saw's hydraulic circuit, which powers functions such as blade depth adjustment and machine propulsion. Maintaining the correct fluid volume is critical — a cracked, damaged, or leaking reservoir can cause pressure drops across the system, leading to sluggish or unresponsive hydraulic controls and potential damage to pumps and actuators. Replacing a worn reservoir with a genuine OEM part like the Multiquip 144003 restores proper fluid capacity and keeps the hydraulic system operating as intended.
