HI everybody first off I should have taken to a mech, but here's what happen I bought a used 700 from a friend, got to ride for about a hour, and one or more rear sprocket bolts came loose and I broke a sprocket. Took the wheel and hub off easy ask my friend how to get the hub off he said just beat it off WRONG answer anyway I bent the fingers on hub. Another friend said that I had to remove an o ring didn't work wound up cutting off with a grinder not easy but got it done. Thinking I got this bought one on e bay used 30.00 bux all new parts 150.00 went with e bay used. Yamaha ordered what I thought was a o ring in the parts pic paid 7.20 waited 7 days came in today its a rubber o ring just what we ordered not what I wanted found out I need a circlip that is not pictured. Cost .57 ordered 2 will this just slide over the axle into the hub from the sprocket side or do i have to remove the brakes and remove the axle? Again I should of taken it to a mech in the first place. I really need some free good advice I hate to go this far and now have to take it to a mech for 90.00 hr please help this newbe wife is already pissed off cuz I broke my toy that I just had to have. You married guys know what that's about lol thanks.
