Rather than replace a noisy draft inducer with an expensive new inducer ($800-$1000 just for NEW parts), I decided to try to replace the 608 ball bearing. The bearing was less than $3 online. I replaced the original double shielded bearing with a double sealed bearing. Hopefully, this will do a better job of resisting water penetration. The inner race diameter of the new bearing seemed to be oversized but I failed to take an accurate measurement of the shaft and bearing. The bearing was a slip fit onto the motor shaft when it should have been a press fit. This is a popular skateboard bearing size but try to avoid skateboard bearings.
Be sure to check out my original video showing how I simply put a few drops of oil into the failing bearing to get my furnace running temporarily for a week+ until I could receive the replacement bearing [ Ссылка ]
