You need to use a thrust washer puller(or something like it). [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCA72&P=0]Heres a link[/link] to one from tower hobbies made by OS. It's got a compression bushing that holds the washer on. You have to apply force against the crankshaft, while pulling against the washer in the opposite direction, and it has to be done with the same tool or fixture.
