Multiquip 12413 Pivot Arm Left Side Assembly - OEM Replacement Part for Ride-On Trowels

The left side pivot arm assembly is a critical component in the blade pitch control system of Multiquip ride-on trowels, enabling precise adjustment of blade angle for optimal concrete finishing. This pivot arm works in conjunction with the Twin Pitch™ control system, allowing operators to synchronize blade pitch between both trowel sets or independently adjust each side by lifting the pitch adjustment handle to disconnect from the system.

Proper pivot arm function is essential for maintaining even blade wear and preventing common finishing issues. Signs that pivot arm replacement may be needed include uneven blade wear patterns, perceptible rolling or bouncing motion during operation, or guard rings rocking up and down while running. During routine trowel arm adjustment procedures outlined in Multiquip maintenance schedules, the pivot arm should be inspected for wear, damage, and proper alignment with the spider assembly.

This assembly interfaces directly with the trowel arm adjustment system, where maintaining a .010 inch clearance specification is critical for consistent finishing performance. Regular inspection of the pivot arm, bronze bushings, and wear plates helps prevent premature blade wear and ensures the trowel maintains proper flatness across the concrete surface.

Compatible with the following Multiquip models:

• HTN27KTCSL
• HTNS5S-2
