With regards to the bearings, the tolerances are machined to be quite tight - so with that in mind, if a bearing cannot go on to a shaft or into its seated position then:
1. Make sure that any burr or turned in edges on the mating part is removed. We saw this in a earlier thread with regards to not being able to get a bearing onto a drive shaft - the reason was burr on the drive shaft.
Keep in mind that all aluminium parts get put through a process to remove sharp edges - this in turn may result in edges being turned in and needing a clean up before a bearing will fit.
2. The bearing must be placed square onto the matting part - if it at a slight angle it may look/feel like it should fit, but it will not.
I always (possibly incorrectly) that everyone stepping up to one of these projects understood that a bearing of any sort had to be properly aligned with the cavity it was to be mounted in before using excessive force to get it in.

Somewhere, in a scrap pile there's the result of quite impatient youth who tried to force a far too large bearing into a diy project some 55+ years ago. One old Fafnir bearing died an honorable death in the process of teaching that youngster that observation and patience win out over brute force!
