How small of a press have you used for rotor bearings? I'm interested in the same for stat gear bearings, but I'm going to guess that if the press can do rotor bearings it can definitely do stat gear bearings. I'm looking at these:

http://www.harborfreight.com/12-ton-...ress-1667.html

Is 12 ton overkill? Not enough? When I built my first motor I think the yokles at a CarEx told me their press was 30 ton, but they managed to **** it up and I had to take the rotors with the bearings they ruined to a machinist.

I know there are other ways to change these out, but I'd prefer this method. With a proper press tool, changing these should be a hassle free task and I'm all about working smarter, not harder. Plus it gives me an excuse to buy another fun tool that I'll undoubtedly use for other things.

Be sure you have proper rotor and stat gear press tool. The right tool for the riogth job...

They work beautifully. Bearings slide in and out like butta.

PS I'm betting that little 6 ton should work just fine but I can't say for sure. I use a 20 ton at a friends shop.

I'm well aware of this, although I may be able to fabricate my own press tools for a lot less cash. The machinist who did my rotor bearings said he used a piece of an old drive shaft for the press tool, I'm sure I can come up with something effective. I do understand the basic principle of having a landing for the axial press stress and the snug landing that sets in to keep the tool from slipping to the side.

This is kind of a preliminary thing, too. It's possible that I won't even need to do this at all, but I wanted to start getting info in case I did. Waiting a day or more to figure out what tool's needed in the middle of the build is a pita.

The press I have uses a 22ton jack. It did rotor and stat bearings just fine. I have used it for quite a few other projects.. wheel bearings/ motorcycle parts/tranny stuff and it has paid for itself at least five times if not more.

This is pretty much what I have.

Personally I would not go any smaller unless you want it for small stuff. For me personally, the smaller ones are useless.

I have never used any "special tool" for pressing the bearings. All you need is half a brain and an ample supply of junk. Those tools would be a "nice to have" but you dont NEED them.

I got the 12 ton from HF for 100 bucks a few weeks ago! It did everything I asked (all bushings). No complaints here, yet!

Agree. But that was never my point. I've pressed in bearings using an old socket and a bench vise with a pipe extension on the handle to press in bearings. Doesn't mean it's the best nor the easiest way to do it.

Whatever you use as a bearing press tool it should be 1) an exact fit to the bearing and 2) of a material that is softer than the bearing (i.e., brass) so you don't bugger up the bearing face of the bearing. Half-a-brains have at it.

FWIW,

harbor freight press works fine. If you need bearings pressed, you can send it to our shop and we can press em in for you and ship it back
