How to replace swing arm bearings
This coveres pretty much all swing arm bearings in utility atv's, I can't speak for sport atv's ?..maybe they are the same ?. here is a run down on how to go about replacing swing arm bearings. tapered bearings..or any swing arm bearings for that matter are pressed in the swing arm. as for after market tapered bearings ?..they are a 2 piece bearing..they have an outter race..and the inner race where the bearing rollers are. you will need to get the old bearing race or bearing out ..depends on what is in there now ?. once they are out..then you put the backing plate in..then the outter race..then the inner roller race..then the dust seal. unless you have a blind bearing puller ??..it's not gonna be easy to get the old races out..this is for sure !..lol. and this blind bearing puller tool is very high dollar to purchase !!. soooo..lets do this the easy way..( my cheaper way ). remove the swing arm, pry out the dust seals. remove whatever is left in the swing arm that you can get out. i'm almost sure your old races will still be in there !. most service manuals will not tell you how to remove them..other than the tool way they want you to do ?..sooo....try doing it my way..tonssssssssss cheaper..lol. ok..first off..some swing arms have it set up..where you can access both swing arm bearings from both sides..and some do not..because Honda was stupid enough to make it hard on us self mech's !..lol. they welded the swing arm solid..so you can not get to the other side completely through one of the bearing sides ?..if they did ?..then you could hammer the other side bearing race out from the opposite side !, butttttttttt..seeing how they welded the swing arms solid on a lot of models now ??. it's very hard to do it this way. soooooooooo..this is how I do it ----> as I said..remove the swing arm..and anything that can be removed..now your looking at the race and the grease tin plate behind the race ( if it's still in there ? ). some after market kits come with everything you need...including the tin grease cap. sooo..your first task is to remove the outter race..this is where you will need that tool Honda wants you to buy ?..orrrrrrr , you do it my way..which requires a dremel with the re-enforced cut-off wheel. now your thinking..how the heck am I gonna get that wheel to go straight across the race while its inside the swing arm ...right ???..lol. very simple...YOUR NOT !!..LOL. first..you have the cut-off wheel sticking out as far as you can have it in the dremel ?..then you angle the cut-off wheel so you can slice through the race..you may or may not cut alittle deep...and cut into the swing arm a tad ??..but it won't hurt it..you won't cut that much from the cut-off wheel to weaken it !!!. ok..now you got a cut in the outter race..now what ??..well..you can go about this two ways..either make another cut right next to where you made the first cut about 1/4 inch away..and hammer and chisel the sliced piece out..this will make the rest of it pry out easier. orrrr..you can just try heating it with a propane torch...and then hammering it out in pieces..PLEASE MAKE SURE YOU WEAR SAFTEY GLASSES AND LONG SLEAVED SHIRTS !!!!..THESE BEARING RACES ARE VERY HARD..AND VERY...VERY SHARP WEN THEY SHATTER !!!!!!. once the races are out..tap in the new grease tin seal, grease the bearing hole up in the swing arm..drive the new outter race down into the swing arm with a hammer and socket about the same size as the outter race...MAKE SURE WHEN YOU GO TO HAMMER THE RACE DOWN EVEN ALL AROUND THE SIDES..OR YOU WILL GET IT IN A BIND..AND IT WILL BE MESSED UP TRYING TO GET IT STRAIGHT DOWN IN FROM THERE !..LOL. once the outter race is hammered down in..grease the inner race up real good..lay it in the swing arm..then more grease..then tap the dust seal in, all done.
