Gearbox sprocket (16T)
16 tooth gearbox output sprocket for the four-speed gearbox, superseded by 57-1952B.
This is the gearbox sprocket, 16 tooth, off the output end of the gearbox where the final drive chain picks up power and sends it back to the rear wheel. It shows up in the parts books under the GEARBOX SHAFTS AND GEARS section, and it's a four-speed box component. The older catalog number for this same part was T1953, and it's since been superseded by 57-1952B, so if you're chasing this down with a different number in hand, that's why.

This one turns up in the catalog across a run of years in the late 1960s into the early '70s, appearing in several parts book listings during that stretch. If you're replacing a worn sprocket or chasing a chain that keeps stretching or jumping, it's worth checking the teeth on this one along with the engine sprocket and chain condition together, since they wear as a set.
Give us a call or check your parts book figure if you're not sure whether your gearbox uses this sprocket or the later 57-1952B version — worth confirming before you order so you get the right one the first time.
