The Multiquip 060303030 Oil Seal TB-30428 is a genuine OEM oil seal designed for MDR-9GH, MDR-9DYE, and MDR-9D ride-on power trowels. As a direct OEM replacement, this seal is manufactured to the exact material grade and dimensional tolerances specified for these machines, ensuring a correct seating fit in the original bore without rework or shimming. Verified compatible with MDR-9GH, MDR-9DYE, and MDR-9D power trowel models, the Multiquip 060303030 is the correct part to reach for when performing a seal replacement or drivetrain service on these units. Sourced directly through authorized Multiquip supply channels, this is the same seal that ships in new production machines.
Key Features
- OEM-Grade Sealing Material — Manufactured to Multiquip's specified compound and hardness rating for oil seals in power trowel drivetrain applications, maintaining proper fluid containment under operating loads.
- Exact Dimensional Match — The TB-30428 profile seats directly into the original bore, with lip geometry matched to the shaft dimensions on MDR-series trowels — no trimming or bore modification needed.
- Confirmed Fitment for MDR-9 Series — Directly fits MDR-9GH, MDR-9DYE, and MDR-9D ride-on power trowels, so you can order with confidence against your machine's model code.
- Prevents Oil Loss and Contamination — A healthy oil seal keeps gear oil or hydraulic fluid contained and keeps debris out; a failed seal leads to fluid loss, accelerated wear on bearings and gears, and potential drivetrain damage.
- Genuine OEM Part — Supplied as a genuine Multiquip component (part 060303030), backed by the manufacturer's OEM supply chain for consistent quality across service intervals.
An oil seal forms a dynamic barrier between a rotating shaft and a stationary housing, preventing lubricating oil or grease from escaping the drivetrain assembly while keeping dirt, water, and debris from entering. On a ride-on power trowel, these seals protect the gearbox and blade drive components that operate under continuous rotational load. When an oil seal wears, cracks, or loses its lip tension, fluid leaks out and contaminants work in — leading to dry running, overheating, and premature failure of the components it was protecting.
