Multiquip 42240 Trunnion Square Double DOF Assembly - OEM Replacement Part

The trunnion square double DOF (degree of freedom) assembly is a critical pivot component that connects the trowel arms to the spider assembly on riding trowels, allowing precise blade angle adjustment during concrete finishing operations. This dual degree-of-freedom design enables both pitch and blade positioning adjustments necessary for achieving proper float and finish on concrete slabs.

This trunnion assembly works in conjunction with the trowel arm adjustment system and spring tensioner to maintain proper blade tension and positioning throughout the finishing process. During maintenance procedures, the trunnion interfaces with bronze bushings mounted on trowel arms and must be properly aligned with trowel adjustment bolts to ensure correct blade pitch control. Regular inspection of this component is essential as it experiences constant articulation forces during operation on the 6-blade radial spider assembly.

Compatible with the following Multiquip riding trowel models:

• HTX6H
• HTXG6DF
