Multiquip 20040 Rocker Block 1.0 Hole - OEM Replacement Part for Ride-On Power Trowels

The rocker block is a critical component in the trowel arm spider assembly that allows the trowel blades to pivot and adjust their pitch angle during concrete finishing operations. This 1.0 hole rocker block design ensures proper blade angle adjustment as the operator transitions between floating and finishing stages, directly affecting the quality of the concrete surface finish.

Designed specifically for the JWN Series Ride-On Power Trowel, this rocker block works in conjunction with the spider assembly, trowel arms, blades, wear plate, and thrust collar to deliver smooth, professional concrete finishing. The precision-machined 1.0 inch hole diameter ensures exact fitment and proper mechanical function within the spider assembly. Worn or damaged rocker blocks can result in inconsistent blade pitch, uneven concrete finish, increased wear on adjacent components, and reduced troweling efficiency.

Regular inspection of rocker blocks during routine maintenance of the gearbox and spider assemblies is recommended to maintain optimal troweling performance on your JWN Series machine.
