Special Tools, get the Honda Crankshaft removal tool, a 20" power bar, an deep well impact socket that fits the crankcase bolt, and a three foot piece of pipe otherwise you'll never get the drive pulley off the crank, which then you won't remove the timing belt cover, and you'll be dead in the water. When I replaced my timing belt and water pump, it took 4 days. 1 full day to tear down and rebuild. 3 days struggling to get the drive pulley bolt broken free.
There is a way to build your own tool, involving a 1 or 2" plumbing end (6 sided piece) and pipe, but I couldn't get it to work. Tool is about $25, try eBay. If you want to create the tool, check for the specs, I think it was on this forum.
Process:
A few days before you start, spray the crankcase bolt with a good penetrating oil. When you're ready, the crankcase removal tool goes on a big rachet/power bar. Turn the crank till the rachet/wrench rests on the frame of the car. Then thru the middle of the crankcase tool insert your socket on the end of your huge power bar, I bought a 6 sided impact deep well socket after shearing off a smaller socket. Then if you can't get that to budge, throw on a piece of three foot pipe or so and break that bolt free. That's the process that ultimately worked for me. Very frustrating. When using pipes to increase leverage be very careful, you are now able to exceed the intended load limit on many tools you wouldn't ordinarily think you could break. Plus you run the risk of shearing the bolt threads which would result in a probable end to your timing belt change. Just make sure everything has good contact/seating before turning the power bar and turn it slowly. I moved the bolt about 1/8th of a turn with the pipe then the rest of the way just the power bar.
The drive pulley sits on tooth, so you can still turn the crank when the crank bolt is removed. Use blue locktite when putting everything back together. Enjoy and breath.
