I want to remove the speedometer drive gear to put it on a different u-joint. Does anyone know how to get the gear off? Or where to get a drive gear? 1940 1/2 ton 4 speed.

When GM sold them,the gear was part # 602798 and fit various 1937-1946 1/2 ton trucks with 4 speeds.
You could contact these people & see if they can help you with your search. Make sure the spiral gear that drives the speedometer gear is OK or you could destroy another gear.

I use a bearing splitter and my press to remove the gear.

Same here Dave, has to be very fine edge on the chamfer though.
