Wheel Hub Cone Removal
Submitted by SpotHound on Fri, 2019-12-13 21:30
For the life of me I can't get the cones/cups/races or whatever you call them out of my hubs to change bearings.
I'm hitting it with a 1/2" mild steel rod and a 2 pound gympie hammer and they never move.
The hub is sitting on concrete.
Any tips?
Can I cahnge bearings without changing the cones?

When you get one out cut through one side with an angle grinder
and use it to hammer the new one in and it wont get stuck.

You need something heavier
You need something heavier than 1/2 inch rod and bigger diameter. I've had some pipe turned down as my bearing race removal/ install kit. Makes life a lot easier.

How
How do you get a socket through the small end to punch out the large cup?

If you have access to a welder, run a bead around the inside diameter of the old bearing cup. Let it cool, cup will shrink and should then come out easily.

1/4" punch and small taps
1/4" punch and small taps with the hammer. Trick is to rotate the punch around the bearing in at least 3 spots (side to side like doing up wheel nuts) so to keep the bearing coming out evenly. Big hits wont knock it out, just twist it and bind up. Been my preferred method for a few decades.

Force
Don't use force, get a bigger hammer. As stated above, give it a hit one side then one one the other side so that it comes out evenly.
Don't throw the old cones away, use them to knock the new ones in with

yeah, bigger hammer, weight beats hitting something hard.
4lb gympie. I use a large punch, as others have said, work your way around the circumference, don't expect it to move if you only concentrate on one or two spots. I have seen Loctite products used to fit them , totally unnecessary unless the cone is a really loose fit. If this has been used, heat may be needed. Once you have them out, put them on a bench grinder to make them a loose fit, to fit the new ones nice and square. then keep them in the tool box for next time.
