Hello Steve, Is the outer track of the outer bearing pushed right in ?
As " Litnman" said, The small outer track, There are 2 types of bearing, Some the outer track is thicker,
And you can't get the OP31 through it, Not that you often need to !,
The first bit of the far end of the sleeve is much thicker, I don't think you would dent the sleeve there ?,
Have you a " straight edge " You could line up on the outside of the sleeve, To see if it's bent,
I would not think it was.
If it was I would have a go a making it straight, Holding the far end In a tube Which is thicker and putting a nice fitting tube in the outer end, If it's scrap anyway, Anything is worth a try ??.
So I think it's down to finding a Bright Spot on the inside of the sleeve and Rubbing it with wet and dry paper.
