Had to replace the busted bearing on my bike before I could rebuild I was given all the parts to do it when I got the bike I was just waiting to use a press and then I decided that I was sick of waiting and just used an angle grinder :0 (carefully!) to hack off the broken bearing and the sleeve.
I had nicked the main shaft 2 times but its still good.. froze it all in my freezer and after 2 hrs took it out , used my heat gun to expand the bearing and dropped it on the shaft.. It worked well but was bit off so I had to tap it down on the inside of the bearing now its good.. put it all back together now I gotta get some blue lock-tight and close the bottom end
I’m thinking of doing a port match and polish along with valve lap along the way any suggestions or tips would be appreciated , thanks!August 15, 2012 at 5:31 am #733Scott KuceraParticipant
Nicely done! Now I know I can tackle my own gearbox rebuild this winter if I need to.

I would suggest doing it with a dremal and a hammer with a chisel to finalize the break in the broken bearing and the collar to be more precise but I just used a grinder with a grinding disk and went a little bit at a time … Also if you do it In a vice it would be much better.
If you don’t have a heat gun you could use a hot plate I think it was around 120 f when it expanded to fit the shaftAugust 16, 2012 at 4:51 am #738Scott KuceraParticipant
I’ve got die grinders and Dremels and a heat gun too. I saw your approach and realized that I can pull it off if I need to. I don’t have a hydraulic press, and I hate paying the machine shop $30 minimum for little tasks like that.

Hi Al. Saw your nice video on replacing main shaft gear bearing. Nicely done.Aint sure bout getting the gearbox opened. Does it mean opening up even engin? Never worked on an Fz 750. Jus acquired it and it has a problem with shifting gears. Thanxx in advace. Keep on with your lessons.I appreciate.September 2, 2012 at 12:18 am #751
hey and thanks , you will need the manual http://anonym.to/?http://depositfiles.com/files/pvwc5luvr or buy one… also yes you need to take it apart from the head to the bottom because of the bolts that are hidden under the head just to split the case! its a big job but I have no experience with bikes and It seems not to difficult.. just study the book.
