Lets see if I got this right Bill.
outer:
MBS 909001R:………Bore=19.057mm/ Diameter= 52.8320mm
Ball Bearing [B01]: Bore=19.044mm/ Diameter= 52.8447mm
I can see how this would work, the roller ID is only .0005” bigger
and the OD is only .0005” smaller.
But I would still use a drop or two of Locktite bearing mount just to be safe.
Inner:
MBS 909052R:………Bore=32.550mm/ Diameter=72.2600mm
Ball Bearing [B40]: Bore=31.760mm/ Diameter=65.1256mm
The ID according to those dimensions is a full 1/32” bigger than the stock ball bearing, even
the bearing mount won’t make up for that much clearance so that would be a pretty sloppy fit
even with help.
Now the OD, if your numbers are correct, is .282” bigger than the ball and there is now way
that would fit unless the hub was bored out.
Don’t think I would like to mess with that one unless of course the numbers are off by a bunch.
