Gear puller for brake drum on 720

Leave the nut flush with the end of the shaft,hold a good chunk of hardwood on it and smack it with a hammer,it is a tapered shaft,if it moves a bit it's loose..
 
Or best yet. Take the brake assembly off and loosen the nut and drop it on a hardwood block on the floor. From about knee height ? Gets em every time. If your adjustment screws are frozen up you will have to remove the assembly anyhow to heat the housing and get them moving again. If they still move loosen them up before trying to remove drum.
 
My Trick for that is a Special RLA tool/bar. 3/4" by 36" one end is ground down to a blunt point.
I stick the bar threw a hole in the cast wheel center, pointed end into the indent of the brake
shaft with the washers off & nut backed off. With a 4 pound hammer I whack the end of the bar, most of the time it doesn't have to be hit very
hard, just a JAR to knock the tapered spline loose. Works every time for me.. Using a puller might be hard
on the drum..
