Multiquip 1215 Spider Assembly 4-Blade - OEM Replacement Part for Concrete Trowels

This four-blade spider assembly is the rotating heart of your walk-behind concrete trowel, holding the trowel arms and blades in a precise radial pattern to deliver smooth, professional concrete finishing. When your spider shows wear, cracks, or blade mounting damage, this genuine OEM replacement restores proper balance and performance to prevent uneven finishing and excessive vibration.

The spider assembly mounts directly to the hydraulic motor shaft and maintains critical blade spacing for optimal concrete surface results. Spider failure symptoms include unusual vibration during operation, uneven concrete finish patterns, difficulty achieving proper pitch adjustment, or visible cracks in the spider casting. Regular inspection of the spider assembly should be part of your routine trowel maintenance, particularly after high-hour operations or when replacing multiple blades.

This spider assembly is compatible with the following Multiquip walk-behind trowel models:

• J36
• J36E2
• JH55C
• PRO36
