Multiquip 2145 Shaft Pivot Rocker Single Joint - OEM Replacement Part

The pivot rocker shaft is a critical component in the spider assembly mechanism that connects trowel arms to the rotating drive system on power trowels. This single-joint shaft enables the precise pivoting motion required for blade angle adjustment during floating and finishing operations, allowing operators to transition between different concrete working stages by changing blade pitch.

In power trowel spider assemblies, trowel arms are mounted in a radial pattern around the central rotating shaft. The pivot rocker shaft provides the mechanical articulation point that allows each arm to adjust its angle relative to the concrete surface. Proper function of this shaft is essential for maintaining consistent blade contact pressure and achieving uniform concrete finishing results. Wear or damage to the pivot shaft can result in uneven blade angles, excessive vibration, poor finish quality, or complete loss of blade pitch control.

This shaft is compatible with the following Multiquip trowel models:

• BHN Series
• HRT Series
• HTN27KTCSL
• HTNS5S-2
