Topic tags/keywords: band saw bearings lower shaft delta

As many of you know I have been restoring an old Delta band saw (28-207) and will soon but up to putting in new lower bearings. I received new ones from Accurate Bearing today.
First, one side of this bearing protrudes beyond the outer race. Does this point in or out?
Second, what is the sequence for putting the shaft and bearings back in the saw? The upper bearings seem pretty much straight forward. Except, again, does the protruding part of the bearing go inward or outward?
Third, where do those two washer things that feel out when I removed the shaft go.
Hope you can help me here. Thanks in advance.

I know it doesn’t help now but I find it can be really useful to take lots of pictures as things are taken apart.

LOL, Yes, I know Mark. Funny thing is I have pictures of every phase of the tear down on this machine…...except for the removal of the lower drive shaft part. Live and learn I guess.

Right now the only thing that I am not totally clear about is the bearing inner race protruding part. I think it goes inward because when I tore the lower part down I don’t remember any inner race sticking outward. The other kind of mystery is that spring washer thing. I think it goes right before the pulley side bearing. I have seen the many drawings say there are two of those. I only have one.

Update on my last entry. I forgot I do have a couple of pictures of that part of the saw. Only problem is they don’t show the right angle. However I do have one photo of the shaft after I removed it.

As you can see this photo clearly shows the protruding race. This tells me that either the PO installed a bearing backwards or it is actually correct. Or my photo is a little misleading because of the angle.
