Can someone please tell me how to go about removing the small rear bearing if it is a tight fit in the Rear Cover of the standard hitachi alternator.

On one alternator that I have the bearing is a tight fit on the rotor shaft. Onthe other the bearing is a tight fit in the Rear Cover.

Thanks for your advice.

How did this happen, can someone please fix it.

The ones I have seen are always on the rotor shaft via a press fit. Odd that the shaft slid out of the bearing.

To remove the bearing from case you will need a small seal puller. The kind with a 90 degree tip. A small slide hammer with inside puller jaws might also fit. The bearing should not be too tight in the case, any tool with a tip to get behind the bearing and tapped, pried or pulled will get it out.

How much room do you have between case and rear of bearing?

The case looks like aluminum and the bearing is steal so heat, about 300>350 degrees F and it will drop out by itself or with gentle taping of the case.

Or use this trick I have used getting clutch pilot bearings out. Find a shaft, punch or whatever will just fit inside the bearing, fill the cavity with grease and drive the punch down into it forcing the bearing out.

Yeah, I had about forgotten about that little trick. It works great too... simple hydralic pressure will knock that bearing right out.

Thanks DriverRider, there is no room at the back of the bearing at all.
