Multiquip 43140-81 Mount Upper - OEM Replacement Part for Ride-On Trowels

The upper mount provides critical structural support for the trowel assembly on ride-on power trowels, securing the trowel arm system to the main frame while allowing proper operation during concrete finishing. This component is essential for maintaining proper alignment and stability during high-speed troweling operations.

During regular maintenance intervals on the STXDF ride-on trowel, technicians performing trowel arm service will interact with mounting components as part of the arm removal and inspection process. The trowel arm system relies on precise mounting to ensure proper clearance and operation of the bronze bushings and blade attachments. When trowel arms are removed for bushing inspection or replacement, mounting hardware must be in optimal condition to maintain the critical tolerances required for smooth operation.

This upper mount is designed to work with the spider assembly and trowel arm configuration, supporting the demanding vibration and stress loads generated during concrete finishing work. Regular inspection of mounting components should be performed during daily lubrication intervals or when performing trowel arm straightness checks with a feeler gauge.
