The "proper" way is to use a 3- or 4-jaw gear puller (you can get a cheapie from Harbour Freight). Thirty-five years ago, I just inserted a couple of flat-bladed screwdrivers under the drive washer and "popped" it loose. This occasionally left dings in the nose of the crankcase, but never seemed to have a negative effect on running characteristics.
Following a crash, when I needed to inspect the insides for dirt or damage, I removed backplate, piston and Cylinder liner and tapped the crankshaft through the drive washer and bearings. Use a piece of plywood or M/M stock to avoid dinging the crankshaft threads.
Today, I just send it off to Frank Bowman for rebuild. I figure that if it hit hard enough to crack the drive washer, the crankshaft needs to be checked for straightness, and there may be other issues as well.
