Working on a friends 2001 sxr 700, pretty sure this bearing was never changed. Had a cheap 3 jaw gear puller on it with heat on collar and snow on shaft, pentrating oil and tight as we could get it with 2 combo wrenches put together for leverage, nothing bent the bolts that connect arms to body on puller. Found a puller in my drawer that has two arms that grab about an inch on each arm and has allen bolts that hold it together right up by the bearing 24" and 18" pipe wrenches tight as possible NOTHING! Finally cut a hole with paddle bit in the plastic (the same size as plugs for suspenion bolts) impact on puller and it fought the whole way but it worked. Plus now the sled is symetrical 2 holes on each side! Win Win.
