ABSTRACT:
The present invention provides an improved system (30) for maintaining the position of a castellated nut (34) on a spindle (31) having an axial bore (33) therethrough. The improved system (30) utilizes chordal bore (36) passing through the spindle (31). After the castellated nut (34) is positioned on the spindle (31) a cotter pin (37) is placed within chordal bore (36). The cotter pin (37) is of sufficient length such that both ends (38, 39) thereof extend from the drilled spindle and engage the slots (35) of the castellated nut (34). Thus, the cotter pin (37) prevents rotation of castellated nut (34) maintaining the proper position thereof.
