1.) 08206-9002 Honda PS Fluid (x4 replace the entire system w/ cooler, probably only x2 if you just want to rebuild the pump)
2.) 91347-PY3-000 O-RING (16.8X1.9)
3.) 91348-PY3-000 O-RING (54.0X1.9)
4.) 91349-PY3-000 O-RING (68.5X1.9)
5.) 91249-P02-003 SEAL, POWER STEERING PUMP
There's also another minor o-ring for the feed housing and the shaft bearing that can be replaced. It's typically the seal that leaks and the bearing that dies, so the o-rings are optional really. The bearing I had was okay, but the seal had a dirt trail that probably meant it was leaking fluid from the seal. I replaced it just because I didn't want to deal with the mess if it did leak after installing it.
1.) Lubricate the inside of the pump housing and outside of the seal. Drive seal into pump housing with the outside of the seal facing the bearing.
2.) Install washer with radiused side facing the seal.
3.) Set the bearing/shaft assembly onto/into the pump housing.
4.) Using the 27mm impact deep socket I have and a hammer, drive the bearing/shaft assy into the housing until it bottoms out into the housing and is completely below the circumferential groove for the snap ring.
5.) Install snap ring.
6.) Flip the housing around and install the spring.
7.) Install the long dowel pin.
8.) Lubricate and replace the two o-rings (not shown). Install the bottom plate.
9.) Install the short dowel pin.
10.) Install the rotor/vane housing. I installed it with the side with the two dimples facing the back of the pump housing. I can't remember which way it came out, but that's the way I put it back in and it works fine. Also, the shorter dowel pin isn't round...it's more of an oval shape, and so are the subsequent holes in every piece that goes on after this one.
11.) Install the rotor on the splined portion of the shaft, and insert each of the vane blades with the radiused ends facing outwards against the rotor housing.
12.) Install the last o-ring and mount the housing's rear plate.
13.) Insert the flange bolts and torque to spec.
14.) Install the drive pulley and torque the LH threaded nut to spec (I torqued it after installing it back on the car).

Can i ask how did you manage to get it out ?
I've tried to tap gently from the rear side with a rubber hammer, no luck... didn't want to break someting.
Could someone help with this matter ?
Were you able to remove the shaft? I tried to place a piece of wood over the shaft tip and hammer it with a metal hammer, but no matter what it just wouldn't budge. I just gave up at that point and replaced all the easily accessible seals that I could get to. Anybody want to offer some tips?
The dimple on the rotor is supposed to be facing out towards the cover if you want to do it right, but it doesn't really matter. You don't need an expensive snap ring pliers to remove the bearing retaining ring, any cheap sharp point pliers will do the job; I used a 3$ one from home depot.
