Rear Wheel Bearing cover

[big r]

I JUST USED A DRIFT AND HAMMER . IF YOU PRY THE SPACER OVER YOU CAN JUST GET THE EDGE OF THE DRIFT ON THE BEARING AND THEN WORK YOUR WAY AROUND THE BEARING TO DRIVE IT OUT. ONCE YOU HAVE ONE OUT THE SECOND ONE IS EASY BECAUSE THE SPACER IS OUT OF THE WAY. I USED A LARGE SOCKET TO DRIVE THE NEW BEARINGS IN, MAKING SURE THAT THE SOCKET IS JUST A SMIDGE SMALLER THAN THE BEARING. DON'T FORGET TO MAKE SURE THAT YOU PUT THE SPACER BACK IN BEFORE YOU DRIVE THE SECOND BEARING IN.

With most bearings, temperature is your friend.
On wheel bearings, put the bearing into the freezer, IN THEIR PACKAGING, until just before you're ready to install.
Heat the bearing socket with a hair dryer or heat gun then get your frozen bearing, unwrap it, and it will seat in the socket with only a very gentle tap.  Still use a socket or other drift to make sure you get it in 'square'.

Heating the bearing and hub with a heat gun also will help when removing the old bearing.

Cheers,

Darn.  Wish I had asked earlier, two of the three are out of the packaging.  But I will freeze the last one.

You can freeze any bearing, in or out of the package. If you are worried you can put in a baggy or ziplock

Make sure it is air tight, you don't want to get freezer burn.

Just wanted to update the thread with my results.  First off, Thanks for all the help in the thread.  The part numbers and freezing tip where invaluable...

The bearing part numbers where dead on and I ordered new Yamaha seals from one of the many part sites.  They killed me on shipping, probably could have found someone better but it was late and I was tired and did not care.  The old seals came out with a small flat head screw driver.   I went and purchase a large socket just for banging out the bearings and putting in the new ones.  Of course banging out the old bearing , with the large socket, seemed like a good idea but really physics was going to stop that idea.  The wheel is grooved, so the bearings can only go so far into the wheel which solved my question on how I would know how far to put the bearing into the wheel.  I ended up using a large phillips head screw driver to bang out the bearings from the opposite side.  There is enough of a lip on the bearing, just take your time and you will have them out in five minutes.  The froozen bearings and a large socket made putting in the bearings very easy.

Again thanks to everyone and I hope this helps someone else.
