Tonight I removed the wheel bearings from the front hub on my 71 Roadster with drum brakes. My questions:
#1
Is the small decorative cover on the left side supposed to have a shoulder on the inside that abuts the bearing spacer? Mine does not, and it looks like it was spinning free of the wheel and scoring the hub itself.
#2 Are the shoulders that the wheel bearings abut in the hub machined in or are they a sleeve that is pressed into the hub? If they are pressed in, is it possible/common for them to shift if the bearings are not installed correctly?
Thanks
 
Thanks-so if that inner sleeve has shifted how do you get it back to its proper position? I would assume mild heat and the proper size drift? Move it enough so the threaded collar bottoms? Will this also affect how the wheel is centered in the forks?
 
I think that's all covered in the 'Workshop Manual'. But go here http://www.oldbritts.com/1971_g17.html and have a look. As I remember the spacer, #10 just sets up the distance from one bearing to the other and to get them out you have to punch one out from the other side. As I say, it's in the book. You know you can get the double row bearing from Walridge and you don't have to machine the hub? But some people don't trust that the bearing is capable. I have one in mine.

And yes, as I remember there's a shoulder on that cover so it doesn't contact anything but the spindle and inner bearing as I remember.

there is no inner sleeve, the bearing outer races sit on the machined hub and the 2 bearing inner races are separated by a spacer.
 
On my Combats the front and rear hub bearings seat by their outter races in the hub bores but the inner races are clamped on the spacer tubes so axle nip up does not bind through the balls, just through inner races as should be, if the spacers are correct length. It was bloody murder for me to get the old rusted bearings out mainly because the spacer tube was a bitch to knock sideways enough to expose inner race lip to beat it out and free the tube to get the other side out. I've cut crude V notches in these spacers so next fella and just put a blunt drift on inner race instead of a sharpned chisel to bit the nil edge exposed in factory spacers. The front spacer of Combats had V shaped additions that centered the spacer on inner races making it so hard to move to the side some.

Thanks-I was pretty sure this was the case. The dust cover has no shoulder left and it rattled around enough on the hub to have worn it to the point the threaded ring stands proud of the hub. Just making sure before reassembling.
Thanks Again
