ABSTRACT:
The combination of a crank arm having a crank pin, a drive link carrying a bushing receiving the crank pin, and a retainer clip adapted to coact with the bushing and crank pin to retain the crank arm and linkage arm in assembled relationship. The clip may be preassembled to the bushing before the crank pin is inserted through the bushing. If so, as the crank pin is inserted through the bushing, a pilot portion on the crank pin is effective to radially spread the clip until a retaining groove on the crank pin becomes aligned with the clip. The clip then snaps into the groove and interlocks the bushing and crank pin against substantial axial displacement relative to one another.
