What did you do in your garage today..?

Other bearing is already out. Remaining bearing is already smashed apart.

The issue is that the inside diameter of the still-pressed-in outer race, is bigger than the lip in the wheel casting inboard of the bearing. A straight object inserted from the other side rests on the cast lip and doesn't touch the bearing race, so I can't punch it out from the other side.

An inverted-cone - the end bigger than the shaft - or something bent sharply at the very tip might be able to get in where the bearing's seal normally sits, but I don't have anything like that.

Had a similar issue.I dremeled two tiny notches just inside of the outer race (material was a lot softer) and used a long skinny punch after heating the hub.

The easiest way to remove a seated bearing is to with a socket and hammer. Put as large a socket as will fit into the backside opening, a few good whacks and both bearings should start to move.

The important thing is to start there - that way the spanner and other bearing help keep things together, less chance of blowing up the seated bearing.

Why can’t you get it from the back? I get the seat lip is bigger - why not hit the inner raceway? or if that’s gone and balls are out, a punch inserted from the back should catch the outer edge of the ball race.

Anything straight inserted from the other side will miss the outer race completely because of the smaller ID of the lip inboard of the bearing.

Anyhow, it's out. One of the other local retired folk was a tool and die maker and still has some machine shop equipment. He made a special tool with a recess to clear that lip. That, plus heating the area with a torch, plus a lot of beating on it with a hammer, got it out. There was a fair bit of crapola jammed between the outer race and the housing, probably corrosion and powdered metal from the self-destructing bearing. It's all cleaned up and the new bearings are doing time in the freezer.

Evotech block off plates came in, so I pulled the pillion pegs.
Stuck on the tank grips. Things were a little slippy on throttle.
Finally got around to downloading the stock ECU so I can do the stage 1 BT Moto tune.
