The Multiquip 0440300160 Oil Seal is a genuine OEM component designed for B46S90 series walk-behind power trowels.

DHS Equipment supplies this part direct, so you can order with confidence knowing you're getting the correct seal for your trowel.
Key Features
- OEM-Grade Seal Material — Manufactured to the same compression and material tolerances as the original, ensuring a consistent, leak-free barrier between lubricated components.
- Direct Drop-In Fit — Engineered to seat correctly in the original bore without reworking the housing, keeping installation straightforward for experienced technicians.
- Confirmed Fitment for B46S90 — Verified for Whiteman B46S90 walk-behind power trowels, so you're ordering the right part the first time.
- Protects Internal Components — A properly seated oil seal keeps lubrication where it belongs and blocks contaminants from entering bearing and gear assemblies, extending the service life of surrounding components.
- Fuel and Fluid System Integrity — Replacing a worn or cracked seal promptly prevents oil migration that can damage adjacent drivetrain parts and create unsafe operating conditions.
An oil seal creates a dynamic barrier between rotating shafts and stationary housings, keeping gear oil or grease contained within the drivetrain while preventing dirt, water, and debris from working their way in. On a walk-behind power trowel like the B46S90, the oil seal protects the gearbox and blade pitch mechanisms that take on constant rotational load during finishing work. When an oil seal fails — through cracking, hardening, or lip wear — lubrication leaks out, contamination enters, and internal components such as bearings and gears begin to wear rapidly, leading to costly repairs if not addressed quickly.
