    I used a screwdriver to drive each seal out from the other side. Didn't seem like a big deal since they were changed with new ones. just be carefull not to scratch the surrounding. FWIW I used a socket to drive the bearing in (Gently - go slow).

    I'm a total newbie shadetree mechanic so take my advice with a grain of salt. On the other hand, it worked great. Two rides with no leaks.

Drain your fluid, and go to town, pull off the side cover and follow the manual, just make sure you look at each seal and how it is placed on each side (inside and out) because they hav eto be placed in a specific direction, I would also inspect the bearing. If you plan on having the bike for a whileyou can do like I did on my 04 and switch out the impellar bearing, inner seal and outter seal. You don't need anything special to pull them and if you have new ones just punch out the old one at a time and replace them, super easy. Then put it back together fill up the Rad and start it and let it run, if you put the seals in backwards it will leak... Yeah I know from doing this :oops:

    do you have to pull the clutch off and apart to take the cover off and i don't have a manual i'm doing everything from memory which so far is a pain but i'm trying to fix my truck, car, and get an apartment so i'm trying to spend as little money as possible and spread the cash around

    thank you very much, so im still wondering why you would drill a hole in the impeller what does that really help
