  • Retainer for pins to support axles under chassis of work machines
    Patent number: 12168383
    Abstract: A retainer for retaining a pin with a section of a work machine. The retainer includes a body to be reversed between a first state and a second state to secure the pin with the section in each of the first state and the second state. The body defines a retaining portion and a securing portion. The securing portion is fixedly coupled to the retaining portion and defines through-holes. In the first state, the through-holes are aligned with apertures of the section for coupling the body to the section such that the retaining portion acquires first orientations relative to the section to engage the pin according to the first orientations. In the second state, the through-holes are aligned with the apertures for coupling the body to the section such that the retaining portion acquires second orientations relative to the section to engage the pin according to the second orientations.
