What kind of puller?

[Jeeper]

Getting a new alternator for this Toyota Avalon I am working on but I decided to see if I could pull apart the old alternator before I return it as a core. One question I use was what type of puller do you use to remove the following bearing. It's the end away from the pulley. There is not a lot of room because of the metal lip. Any ideas?

Hydraulic press?

How does the fan with the lip come off? It would seem to me the bearing should come off that end.

It doesn't. It's part of the rotor. Tack welded to it.

I don't know if you'd be able to get the jaws of a thin bearing puller in the space you have. An alternative is to cut off the outer race and use a 2 or 3 jaw puller on the inner race.

OTC makes a small hand screw type 2 jaw puller. It may fit between the bearing race and the dust cover towards the rotor. The real tool would be on the likes of a power steering pulley puller. 2 halves slip down over the bearing, a tube fits over the 2 halves so the pieces don't come apart, then a top hat and screw pull off the bearing. The fan is spot welded to the rotor half. the little tin cover under the slip ring is a dust slinger. The tin cover is press fit on. The bearing is also only press fit. If you are really interested in the proper tool, call Vensel Enterprise, they can help you with the proper tooling to do these in multiples. Hope this helps.

I have a SO alt pulley puller for older Chrysler alternators that might work on that. If not , I would also cut the bearing and pull on the inner race,

I watched that video. Sort of disappointed that he cut the bearing off and cut though part of that dust slinger. Firgured it would be more professional. Workable yes but figured there was a better way.

What were you watching ???!!!

At 10:01 he pops the bearing of with 2 pry bars !

By bad. Thought it was the video I linked below. Same guy. The one you link to doesn't have that dust lip around the bottom of the bearing. So if you try pry bars, it would bend the lip and more if the force would be pushed in on the shaft vs pushing the bearing up.

The link below has the style of rotor that I pictured above. At 35:50 he just cuts the bearing off. Works but not he cleanest.

I'd weld nuts to the old bearing to give something to grab with a regular 2 jaw puller.

I have had good success removing the dust shied and using a puller like in the video.

That Simatool puller setup appears well thought out.

That is a very neat (and expensive) tool. I like it!

 

[shawhite]

we actually have the skf version of this tool It was s little cheaper.

What about a battery terminal puller? I just replaced the alternator in my wife's Av as well but didn't have the time yet to break the old one apart to see the inerts.

Good idea but they they just don't have the reach.

Would a bearing separator fit in there?

Otherwise, if I really had to get this bearing off I'd weld nuts to it or grind down a set of puller jaws to fit.

No dice. Bearing splitter won't fit with that lip there.

My first thought was to use a couple of pry pars to lift it using the fan shroud as a fulcrum. What are you trying to salvage here? Or just taking it apart for grins? I've always worked under the assumption that a bearing pulled by the outer race is not to be reused.

no neat sig line

Wouldn't the 1 or 2 copper armature pieces have to come off first. Then hold the bearing in a vise, and use a brass punch to drive the shaft through the bearing

Just a quick glance, you would think it comes apart from the fan end
