Multiquip 2791100221 Main Bearing Cover C

The Multiquip 2791100221 Main Bearing Cover C is a genuine OEM replacement designed for the B46S90 walk-behind power trowel. Sourced directly from Multiquip, this cover delivers the exact material grade, dimensional fit, and surface finish required by the original design. If you are servicing a B46S90 trowel, part number 2791100221 ensures you are installing the correct component without guesswork.

Key Features

• Genuine OEM Construction — Manufactured to the original material and dimensional specifications, ensuring the cover seats and seals against the bearing housing as intended.
• Direct Drop-In Replacement — Matches the original mounting points and profile of the B46S90, allowing straightforward installation during routine service or bearing replacement.
• Confirmed Fitment — Verified for the Whiteman B46S90 walk-behind power trowel; always cross-reference your model and serial data before ordering.
• Protects Critical Bearing Components — A correctly fitted bearing cover keeps contaminants out of the bearing assembly, preventing premature wear and maintaining smooth trowel blade rotation.
• Maintains Structural Integrity — The cover contributes to the rigidity of the bearing housing assembly; a cracked or missing cover can accelerate bearing failure and lead to costly drivetrain damage.

The main bearing cover serves as the protective enclosure for the bearing assembly at the base of the trowel's rotor shaft. It shields the bearing from concrete slurry, dust, and debris that are present during finishing work — contaminants that would otherwise accelerate bearing wear and cause shaft play. When this cover cracks, warps, or is lost during service, the exposed bearing becomes vulnerable to rapid deterioration, which can result in uneven blade rotation, increased vibration, and eventual shaft damage.
