Be very careful not to damage the thrust plate behind the gear as you press the gear off. It's also possible to drill and tap a couple of holes in the gear and use a bolt-on puller like one for a harmonic balancer to remove the gear- - - - -and it doesn't prevent the gear from being reused if you want to. I never reuse a timing gear, however- - - -new ones aren't that expensive.
