Piece of bearing stuck on spool shaft

[FatTuna]

I have a reel that had a badly corroded bearing seized onto the spool shaft. It's a Senator 114H. I was trying to pull it off with a pair of vice grips. When I applied pressure, the bearing literally exploded in to pieces. The inner part of the bearing still remains on the shaft. It's really stuck on there. Any ideas?

Nothing magic, but a long (overnight) soak in penetrating oil might help. Also cycling between hot and cold can take advantage of the different coefficients of thermal expansion of the different metals, that might free it up. Last ditch effort would be to grind carefully with a dremel.

I'm pretty decent with a dremel tool. I might have to resort to that.

I tried soaking it in mineral oil.

I'll try the hot/cold trick.

Thanks Sid.

I concur with Sid and Joe. Good soak in penetrating oil first. After that, hot and cold are your friends. Get that bearing race good and hot (but not red-hot) on the stove (provided it's gas) then sandwich the shaft between two ice cubes (be careful of steam). This works.
Good luck

Good advice from the guys above.
I usually pop the outer race, this allows me to grab the inner race and turn it back and forth.



It has worked for me, but if it still didn't budge, I would grab the dremel.


Oops, I just noticed that you did remove the outer race, disregard my comment.
Good luck!

Thanks guys. I'll let you know how it goes.

I think Joe hit it.  If you grind it with an abrasive bit it may get so hot that it pops off before it cuts through.  Trying to heat it with a flame would be scary and not very focused.  You can wrap a piece of wet paper towel around the shaft to pull heat away from the shaft while you grind on the bearing race.

Dremel and cut-off wheel will usually do the trick.
I usually try a micro flame gas torch (very precise) then plunge shaft and bearing into cold water (or ice bath)
If your dealing with baitcaster size components I protect delicate areas with a plumbers soldering mat then hit it with the micro flame.

To echo the hot and cold procedure already mentioned...

Plumbers pliers were used to crush the outer race, cage and balls - captured inside a plastic bag - leaving only the inner race behind:







Three cycles of heat (applied by an eagle jet torch) and ice, followed by a drop or two of oil and the inner race was gripped with plumbers pliers and removed with minimal fuss:

I have used a small vice grip to clamp on the race and twist after using penetration oil and let sit for a day. Then twist the spool.

I like Bryan's suggestion, and have used this method many times with successful results.

Heat. That works!
