Multiquip 21310 Spider Assembly LS 4-Blade 28K - OEM Replacement Part

The spider assembly is a critical rotating component in power trowel machines that connects the blade arms to the gearbox drive shaft, distributing power evenly across all four blades for smooth, consistent concrete finishing. This LS (low speed) 4-blade spider assembly rated for 28K applications ensures proper blade pitch control and balanced operation during the critical floating and finishing stages of concrete work.

Designed specifically for demanding commercial concrete finishing applications, this spider assembly maintains precise blade geometry and timing throughout the troweling process. Signs that your spider assembly may need replacement include uneven blade wear, vibration during operation, difficulty controlling blade pitch, or visible cracks and wear on the spider arms. Regular inspection of the spider assembly during routine maintenance helps prevent unexpected downtime on the jobsite.
