Cotter nut
A cotter nut used in the gear cluster and timing cover area of the engine, cataloged as 57-2706 (also T2706).
57-2706 is a cotter nut used in the gear cluster area of the engine bottom, per the parts book listings it appears under. Its older alias, T2706, is the letter-prefix form you'll find in earlier parts books covering the same part before the numeric system took over.

A cotter nut like this secures a cotter pin or cross-pin arrangement, holding a shaft or lever in place against rotation or working loose. The catalog places this one in the gear cluster and timing cover figures, so it's tied to work in that corner of the engine.
If you're pulling the timing cover or working in the gear cluster and need to replace this nut, check your own parts book against the T2706/57-2706 numbering to make sure you're ordering the right one, and give us a call if anything doesn't match up.
