how do i get the bearing behind the flywheel out?

[Traxxas_Junkee]

As it says i have a trx 2.5 and i can see that there are only a few balls left in the bearing and i cant get the actual bearing out, if thats what it is. i took it out because the motor died and then oil was everywhere and oil smoke was coming out of the exhaust. anyway how do i get the bearing out?? i have another wone off of a blown motor but i need to know how to get them out. thanx (sorry about all of the threads l8ly)
