Bearing race removal success
Put the hub in the freezer overnight, went to my local hardware store and picked up a USA made 12" long drift punch, a few hits with the ball peen and it came right out. With the right process and the right tools thing are so much easier.

Re: Bearing race removal success
It always worked for me, but with just the drift, not the freezing.

Re: Bearing race removal success
I sometimes run a weld around the inside of bearing race and let cool, the weld tends to srink the diameter of the race, this was a common practice where the race was installed in an aluminum hub. I also used the same method to remove stubborn dry type cylinder liners from diesel engines as to avoid damaging engine blocks from the use of a liner puller .

Re: Bearing race removal success
Use a large diameter drift punch or a round rod to drive them into place.

Re: Bearing race removal success
Like others have said, I just lay a nice thick bead on the race. Let it cool and it will slide right out. Avoids mangling the parts or your fingers.

Re: Bearing race removal success
Re-installation: I have a Harbor Freight hydraulic press - best damn thing I've bought recently (think it was about $200). It was a necessary investment for me to be able to build Banjo Rears, but it comes in handy for a LOT of bearing related activities (both on and off). BUT - it would not have helped me take the race off (in your case) . . . but I'd sure use it to put one back in.
PS: The weld bead trick -- really works in a situation like a banjo housing - where you need to get the race out of the bell side . . . and it would take a LONG punch to do so. Another trick: Sometimes I'll weld a "bar" across an inner bearing race - so I can pull it out. |
