I haven't found any method that works well without using a pinion puller. The problem with not using one is that usually the motor ends up destroyed, and the teeth of the pinion usually get damaged as well. One way you can gain some pinion clearance for the puller is to use a pair of large diagnal pliers, and put the gear into them like you are going to cut the motor shaft off just below it. Squeeze the pliers, and you will move the pinion about 1/16th of an inch. Enough to get the puller in, and not kill the motor.
