This bolt secures the lower link of a three-point hitch to the tractor chassis, providing the pivot point for the stabilizer mechanism. It is installed at the connection between the lift arm and the stabilizer strut, where it must withstand both tensile and shear loads during implement operation. A worn or elongated bolt hole introduces play in the linkage, causing the implement to drift laterally during transport or work. The bolt is manufactured to match the original thread profile and shoulder dimensions, ensuring it seats correctly in the clevis without requiring additional shimming. When replacing, clean the bore and apply thread-locking compound to the nut per the torque specification.
