Bearing help

The larger the nose radius the more durable the edge, round inserts
being the largest nose radii. But I did not want to confuse Timmy.

There's an end to the saga!

Friend offered to help me out. A few minutes with a die grinder to cut out the weld and an air chisel to punch the bearing shell out...

Just about good to go and lesson learned.

I don't think you fucked it up too bad... Make sure the bore is smooth with no nicks and the flange is perpendicular to the bore before you press the races in. If you don't have one already you should get a race driver kit...

That race driver set is a perfect lathe learning project for Tim.

Nice job of welding the race to the hub. H'mm I wonder why it wouldn't come out

This 3 ton arbor press that I forgot I owned should be enough to press in the new races, right?

Yep, that'll do it

Before you get carried away, get out the measuring devices and measure the OD of the bearing race and the ID of the bore it's going to be pressed into. Typically those things only have a couple of thousandth's interference fit (.002")
If you have to use 3 tons of force to push that race in, it will either distort the bearing or crack the bore. I put similar races in using a 2 lb copper hammer and the correct sized bearing driver.

Doc, you're no fun, I wanted to see what he did first...

Metal shards to my chest?
