to fig3 a rear perspective view of an example of a top drive assembly 10 is shown in a perspective view in this example embodiment the motor housing 27 is disposed proximate to the torque restraint 25 also shown in fig3 is the lower pivoting connection of the elongate member 41 a pair of clevis hinges 42 are shown mounted on a side surface of the motor housing 27 and set a lateral distance apart on opposing lateral sides of the elongate member 41 in the example embodiment of fig3 the clevis hinges 42 each have an upper portion with an outer side wall that slopes away from the motor housing 27 defines a peak then slopes back towards the motor housing 27 and terminates at a location between the upper and lower ends of the clevis hinges 42 an inner side wall on the clevis hinges 42 disposed adjacent the elongate member 41 projects outward and parallel with the outer sidewall but extends substantially the entire length of each of the clevis hinges 42 bores are formed through the inner and outer side walls of the clevis hinges 42 at their respective upper and lower ends bores are also provided in the lower ends of the linkage members 36 that register with the bores in the upper ends of the clevis hinges 42 pins 44 are inserted through the registered bores in the lower end of linkage member 36 and upper ends of the clevis hinges 42 thereby pivotingly coupling the linkage member 36 with the clevis hinge 42 because the outer side wall terminates above the lower end of the clevis hinges 42 the bores.
