Which tool gets the most grip on a stuck bearing race?

---

I have a state of affairs with the outer race of a cartridge bearing that is stuck inside an integrated headset cup. The inner race and ball bearings were completely torn out while attempting to remove the bearing.

I managed to borrow a slide hammer and a bearing puller attachment but the hooks tend to slip out when I utilise heavy strength.
This is what the zipper looks similar:

Has anyone had whatsoever experience with other models of bearing pullers, or this style of bearing remover:

Only a tiny department of the race protrudes from the cup so I demand something that can actually dig into that tight space.

I've tried penetrating oil, but the damn affair is stuck very tightly. I've likewise read about the welding fob, simply unfortunately this is a carbon frame so that's out of the question.

Sure, try the split up "cup remover" tool. But in the stop if it fails bring out the Dremel with a stone and grind away with intendance. And so in the time to come service the unit more frequently and grease the cartridge's out sides each fourth dimension. Andy.

The "Rocket Tool" yous show in your lower photo is THE recommended tool for removing press-in headset cups. If y'all take a stuck race in an "integrated" headset, that'southward a different problem.

Are you sure of the issue? I can't call back of any machinery that would have a headset outer race stuck like that.
What type of headset? Integrated, semi-integrated, conventional?

Whole cup assembly comes out of the frame with the "rocket tool", if the bearing came apart,
and all the balls vicious out , y'all probably accept to re buy the whole headset..

>>the manufactuting was not intending just removing the bearing.. <<

CK?, just ship it to them, they will replace the cartridge.

integrated , they slip out of the machined head tube ..
unless frame damaged or really corroded from riding in bad conditions a lot (due west/o mudguards)..

every bit above :

I have a one inch threaded caput set that has this problem. The upper is fine. On the lower it is a PITA to install/remove the cartridge begetting. The upper and lower bearings are identical. I swapped them and all the same had the problem. So in my case it'due south the lower cup that was machined just a little scrap too small-scale.

Sad, I should have clarified that it's an integrated headset. The problem is identical to this (not my picture):

It's an integrated headset, but the cartridge bearings do press into the cups.

It was a second hand purchase and then not much I could accept done to prevent it, but I certainly will in the future. By "stone" are yous referring to this type of bit?

What should I be trying to exercise with the Dremel? Weakening the race to become information technology to pop out or grinding through to the aluminum cups?

OK, it is indeed an integrated headset and bearings are inserted into cups formed as part of the headtube. The Rocket Tool is not intended for ane of those, it's used to remove separate cups pressed into the headtube.

Wow, never thought of that happening merely could run into information technology on a neglected bicycle or a wintertime driver. Steel cup and aluminum frame.
I estimate you could try warming the frame upward merely below the point that information technology will boil a drop of water and see if it will assistance, maybe an water ice cube on the loving cup at the same time.
Using a Dremel with a cutoff disk, you could brand a small-scale relief for the remover jaws to fit more secure.

If steel expands less than aluminum under heat I can see that working, just I'grand rather hesitant to be boiling carbon fiber.

Unfortunately, the claw ends of the jaws I accept on manus are squared so they wouldn't be able to fit into any relief created within the bearing itself.

I was thinking maybe something that looks more like this where the hook ends are angled could dig in better to the available relief above the bearing. The but affordable place to get i of those seems to be from China off eBay so I wouldn't desire to order ane without whatsoever indication that it works improve.

Since I do have a Dremel on paw, I'm leaning towards some sort of excavation if I can get some feedback from someone who has done it successfully.

Ah, forgot the moving picture wasn't your bike.

Ah Loose Ball Integrated headset .. yea the screwdriver and something to lever confronting < equally shown>
(cone wrenches for their steel,+ being handy in the Shop, not as a wrench)
and work your fashion around a Petty at a time is probably the Plan..

But since thats a picture of some 1 else'due south bike, Its a solution to their issue, may exist non Yours ..

Welp, I finally got it off.

I noticed using the slide hammer that I was getting one side to lift a petty, maybe due to uneven corrosion. But considering of the tight tolerances, getting one side crooked will arrive harder to elevator out. So I repeatedly drenched it in penetrating oil and kept tapping the one side dorsum in and out which must have helped work the oil into the other side, until I could get the whole thing out.

I likewise had the penetrating oil soaking overnight which must have helped get that initial side moving.
