What should I put inside?

3 posts in this topic

I cracked the case on my 03 wr450, so I have to pull the whole motor apart to replace it. I get all my Yamaha parts at dealer cost so I am trying to figure out all the parts I need to freshen it up. Since I am in there what bearings do I need? Someone told me that some of the bearings are pressed in and they won't come out clean from the old case. Also since I am in there is there anything else I should do? Any help is appreciated. Thanks, Dan

You are better off asking an engine builder, or if you trust your dealership.

I just rebuilt my motor.... a little heat and the (crank) bearings will pop right out.
