Multiquip 21307 Spindle Clutch 3/4" Bore - OEM Replacement Part

The clutch spindle is a critical rotating component that transmits power from the gearbox to the spider assembly and blades on power trowels. This 3/4" bore spindle interfaces directly with the blade attachment system, ensuring proper rotation and load distribution during concrete finishing operations. When a spindle shows signs of wear, wobble, or damage, it must be replaced immediately to prevent uneven blade movement and compromised finish quality.

Designed specifically for Multiquip walk-behind power trowels, this spindle maintains the radial blade spacing required for uniform concrete surface treatment. The 3/4" bore dimension ensures proper fitment with the vertical rotating shaft assembly. During maintenance, inspect the spindle for scoring, eccentric rotation, or bearing surface degradation—any of these conditions indicate replacement is needed to maintain trowel performance and operator safety.

Compatible with the following Multiquip trowel models:

• J3036H55
• J36
