The Multiquip 502302840 Oil Hose 1/4 320L is a genuine OEM component designed for MDR-9DYE, MDR-9D, and MDR-9GH ride-on power trowels. As a direct OEM replacement, this hose is manufactured to the exact specifications required for proper oil routing in these machines, ensuring a correct, leak-free fit right out of the box. Sourced directly through Multiquip's authorized parts channel, 502302840 is the same hose installed at the factory — no guesswork on sizing or compatibility. If your trowel is showing signs of an oil leak or a damaged hydraulic hose, this is the part to restore it to full working condition.
Key Features
- OEM-Grade Hose Construction — Built to withstand the internal pressure, temperature range, and oil type used in MDR-series trowel hydraulic systems, delivering the service life the machine was designed around.
- Exact-Length Routing Match — At 320L, this hose is cut and configured to route precisely within the MDR-9 trowel chassis, connecting to the correct ports without modification to fittings or brackets.
- Verified Fitment for MDR-9 Series — Confirmed for MDR-9DYE, MDR-9D, and MDR-9GH ride-on power trowels, covering both diesel and gas-powered variants in the MDR-9 lineup.
- Maintains Hydraulic System Integrity — A failed or leaking oil hose can starve the hydraulic circuit, causing erratic blade pitch control or complete loss of drive function; replacing it promptly keeps the trowel operating as intended.
- Genuine Multiquip OEM Part — Supplied under part number 502302840 direct from Multiquip's parts program, so you receive the exact component with correct material spec and end fittings already in place.
An oil hose in a ride-on power trowel carries hydraulic fluid between key components in the trowel's hydraulic circuit, including the pump, motor, and blade pitch control system. Without a properly functioning hose, oil pressure drops, leading to sluggish or unresponsive blade adjustment and potential overheating of hydraulic components. A cracked, pinched, or leaking hose should be replaced promptly to prevent secondary damage to the hydraulic system and keep the trowel performing consistently on the slab.
