Inner cam bearings, how far below?
I'm putting new bearings in. Its an 06 ultra classic. I bought the tool from heartland products, I think the tool screwed up my new bearing. Its either pushing it too deep or it has too big of a radius on the inside corner of the installer tool, and its bending the edge of the bearing.
Anyone else had a problem with that tool? I can fix the tool I just need to know how deep it is really suppose to be. good thing I work at a machine shop! Guess I should have made my own tool.

When I did my cams I just used the old cam with the new bearing on the end of it. It works great to lightly guide the bearing in as you tap the end of the cam with a rubber mallet. I'm a shade tree mechanic but I pretty sure the bearing should seat all the way into the hole. You can't push it in too far. I may have heated the case a little bit before putting in the new bearing too. It expands the hole a bit and with some assembly lube they go in surprisingly easy.

The bearings should be installed with the numbers facing out; the leading edge of the bearing cage (inside face) as a slight taper to facilitate starting the bearing into the bearing boss. There is a shoulder on the inside of the case and if you seat the bearings hard against that shoulder, the bearing cage can distort and lock up the rollers so they won't "roll". The bearings should be pressed in past the face of the case by about .025" to avoid a "hard" seat as described above.
Next time freeze the bearings over night, liberally apply assembley lube to the bearing cage and the bearing bore and they should slip right in. You should feel more resistance when the bearing cage is fully seated in the bore. Back off on the tool and check; if not quite inside the bearing bore, use the tool to press it in a little further.
