A/C blower motor oiling
Wondering if anyone has ever run across a GE model 5XBPO42D 1/3 HP furnace blower motor. It has stamped on the front to reoil with SAE 10 every (light/medium/heavy): 25000 hrs/3 yrs/1 yr. I don't see any oil ports or plugs, but I might not be looking in the correct spot. Just wanting to know if I have to pull the thing down and disassemble it or if there might be a plug I'm missing. Or do we let sleeping dogs lie? It doesn't make any unusual sounds, no smoke, and we only operate it on the hottest summer days. We heat using steam, so it sits turned off all spring, fall, and winter.

Somewhere on the bearing housings — not on the ends — there will be a small hole (may or may not have a cap) which is intended for oil. Without looking at the side of the thing, I couldn't say for sure. But it's there.
A little oil. Don't get carried away.

Are these the oil holes for different orientations or are those for some sort of mount with index pins?

If it says oil then there are usually oil ports one on each end of the motor. They could be behind the resilient motor mounts where you can't see them.
Easiest way would be to take the screws out of both resilient mounts and pull the motor out where you can see things. This would prevent having to unbolt the motor and getting it out of alignment. When you remount the motor position the oil holes at 12 oclock.

If you loosen the screws on the clamps and rotate the motor in place clockwise as you look at the picture, you might see the ports.

Yep, the yellow arrow marked the spot(s) one on each end. Thank you! Last question…is Supco Zoom Spout Oiler MO98 an appropriate oil to use? I can't find it's SAE info. Edit to say, I found another extendable spout one at Grainger that is clearly marked SAE 10 machine oil, so I'll go with that. Buck cheaper too. Thanks again for all your help!

Either one is fine. You can also get sae 20 nodetergent oil at the hardware store as 3 in one motor oil.
Air tool oil is usually sae 10 but it really doesn't mattter here.
