That's where a shaped block of wood, a properly sized nail or bolt, and a HF (45 bucks, 38 or so with 20% off) 1 ton arbor press equipped with a cheater pipe comes into play. Then a good gear puller and a flat piece of metal with a relief cut to clear the shaft that the gear is pressed onto...
The cheapo arbor press has made several things much easier to do. Well worth the money.
