Alternator bearing removal?

[dlundblad]

How does one remove this bearing? It’s pressed in and not accessible from the other side.

Thanks in advance.

Can you get a puller on the other side or is it flush?

Get it nice and hot, pull the bearing out with a pick.

That's a tricky one that looks like a throw away pulley.

On to the spiel...
Take it to a machine shop. Even the ones I've been able to get out end up getting gouged trying to get them out w/non ideal tools. BUT by that time it might be priced out w/waiting to just see if you can buy another new pulley. Let us know what you decide.

Assuming you don't want it back, destructively. The question is what sort of tool will get the outer race without gouging the backside of the pulley. Once you cut a slit in the outer race you can pry it inwards and relieve all pressure and it'll come out. A few nicks in isolated areas of that pulley shouldn't matter.

Use the bread trick...

a slide hammer?

Drill out the backside to then press it out?

Fill that cavity with grease. The use something piston like to push the grease down into the 'bore'. The pressure should force the bearing out. Same as pressing out a clutch pilot bearing that sits in a flywheel.

You can also pull up the brown grease seal with the corner of a razor blade and see if you might be able to get a screwdriver under it and walk it out that way.

Simplest answer. What are a couple 1/4" cosmetic holes? Do two dimetrically opposite if you're concerned about balance.

I can't imagine repairing an alternator in this day and age. Thats just me.

^ Wow, what application would require a $750 alternator? A D8 Caterpillar maybe? Last summer I bought a new ac/delco 180 amp alternator from Rock Auto for $180 shipped with no core charge.

Water cooled alternators in new cars. 48v in some cases.

It’s a little laboratory turn table that happens to use an alternator bearing.

I may go that route. Thanks.
