2001 WR426 rear bearing replacement???
Posted August 10, 2002 - 11:59 AM
How hard is it going to be for me to replace my rear bearings, they are making a grinding noise periodically. How much time do I need to set aside for this repair? Any tricks or suggestions will be most appreciated!
Have a great weekend and ride safe!

You should measure how far your bearings set inside the lip of your hub. You can (as I have ) push your bearings in too far >> hence measuring BEFORE starting the removal process.
The most difficult thing is getting the bearing initially pushed far out enough where you can get a better bite on it w/ your punch. I have used a screwdriver in the past to get started, although last time the drift punch worked fine.
Take your time and work your way around the bearing. You may have to go in a 4 bolt per-se pattern when tapping it out ( 0 degrees, 180 degrees, 90 degrees, then 270 degrees ).
For installation, I have put my bearings into the freezer. I myself have never heated the hub for expansion, although I have heard of others doing it. I use a large socket to tap my new bearings into the hub. You must work slowly and keep that bearing going in straight.
Keep those measurement numbers handy when tapping in your new bearing.
I WOULD NOT recommend Yamaha bearings >> too expensive and quality can be improved w/ aftermarket. Go to a bearing supply store w/ your old bearings. They will measure it or cross reference it w/ their bearing book. There are reference #'s on your old bearing.
Good luck but you WILL be fine!!
