One or both of the bearings are growling pretty bad. Thought I'd replace them both while I had it apart. The bearing on the shaft end was no problem to remove. What's the best way to remove the bearing from the blind hole at the opposite end? It has no retainer - just appears to be a press fit. Thanks, Paul [Reply]   [No Email]

I'll try the grease first, then the heat, then maybe both. If that doesn't work, I'll go from there. My oldest son is a mechanic, and has every tool imaginable, it seems. I'm sure he has a little puller for pilot bearings, but I don't like to borrow his tools. He makes his living with them, and doesn't need them scattered all over the county. You're right, 36 coupe, I should get the right puller, and I might end up doing just that. I'm a sucker for tools. . . Thanks again to all who responded Paul   [Reply]   [No Email]

If the bearing is still in one piece, that is, with the inner race still in place, this method won't help.   [Reply]   [No Email]

Fill the center of bearing with grease and drive a bolt into the bearing shaft hole. The preasure from the grease will drive the bearing out.   [Reply]   [No Email]

If NOT, a small 3-jaw internal puller would be the tool to use. Lacking that, you can drill a hole from the outside for access to press the bearing out, then cover it with a snap-in button plug. Same motors are made like that from the factory.   [Reply]   [No Email]

The ends are cast iron, which is probably to my advantage over aluminum. If the heat won't do it, I'll drill through the end. I don't have a puller small enough to get inside the shaft hole - 5/8".
