Gearbox sprocket (19 th)
A 19-tooth gearbox sprocket that drives the primary chain out of the gearbox mainshaft.
T1476/19 is a gearbox sprocket with 19 teeth, the sprocket that mounts on the end of the gearbox mainshaft and carries the primary chain back to the engine sprocket and clutch. It lives in the primary chaincase, and the tooth count on this one determines the overall gearing along with whatever engine sprocket you're running.

This part number shows up across a run of catalog listings from the mid-1960s into 1970, all filed under the chaincase and chains section of the parts books. If you're rebuilding a primary drive or chasing a gearing change, this is the piece that sits on the gearbox side of that chain.
We don't have more detail on this one beyond the tooth count and its place in the chaincase assembly, so if you're not sure this is the exact sprocket your gearbox takes, give us a call before you order.
