How Hard Is It To Rebuild a Power Steering Pump

I walked out in the garage the other day and saw a large puddle under the left front of my 66 300.
Upon raising the hood, I saw that the front seal of the PS pump was leaking.
I'm just glad it held together till I got home from Power Tour!!
Anyway, I ordered the PS pump seal repair kit from RockAuto.com.
Part Number Part Type Price EA Core EA Quantity Total
1966 CHRYSLER 300 6.3L 383cid V8
GATES 351400 Power Steering Pump Seal Kit $ 10.24 $ 0.00 1 $ 10.24
Discount $ -0.51

My main question is: Do I need a specific puller to get the pulley off the pump shaft without bending anything?
And what about reinstalling the pulley?
You can't just beat it back on, I wouldn't think.
Any thoughts or information?
Thanks in advance.
