Sno Tek Roller Bearing-Stuck

Good Morning All,

I'm in the process of removing the roller bearings to change the friction disc on my neighbors Sno Tek (920402) and for the life of me cannot get the roller bearings off so I can slip the axle out to get to the friction disk. I've tried soaking with PB Blaster with no luck. I can try to heat it up but I'm afraid I will cook the bearing. Worse case scenario I can cut them off but would rather do that in a worse case scenario.

Does anyone have any tips to get these off?

Thanks and Happy Saturday!

Let me go look at the schematic for that unit, as I don't have that unit, but that bearing looks to be pressed on, and I highly doubt that would need to be removed just to change a wear item like a Friction Disc.

Update ::

According to the replacement video I posted below, indeed that bearing should slide off. It apparently has seized itself on the shaft, and a puller is what I would use to remove it … just make sure you are in center of the axle, and do not mushroom the shaft end. Some Trizol and a hammer drill or air gun will assist in shocking it as it is drawn off the axle. Make sure you clean it with some fine emery, and apply some NeverSeize before re-assembly.

If you don't have the puller that oneacer suggested, you can try driving the hex shaft out of the bearing with a flat punch and a hammer. Make sure the hex shaft is free to move in the direction you drive it. It's not the best thing to do to a bearing but you probably won't hurt it and at worst you can replace the bearing. Start with light strikes and hit harder as needed but don't bend up the transmission case. You can place some steel bars under the bearing to distribute the force on the transmission case. You can get the owner/operator manual here https://www.snowblowersatjacks.com/Images/Ariens/guides/920402.pdf if you don't have one.

Here is your Parts Manual, you will want to save it if you don't already have a copy :

The bearing should slide off pretty easily, Try tapping it as toromike suggests, Here are the parts from a Sno-Tek I replaced it on and you can see the bearings off. Also it seems many different brands all use the same wheel as I ordered for the Sno-Tek and the package had Snapper on it but was a exact match to the old one.

Sno-Tek Modded, 15"X-Track tires (Now has same X-Track tires but 13"x4" for better fit), 254cc engine LED light and hand warmers.
Snapper 6/22 sold but not forgotten. Was my first.
Ariens ST1027LE workhorse and going strong.
New 2017 Ariens Deluxe completely rebuilt after losing a fight with a forklift.

Thanks for all the replies. I tried all the suggestions and still nothing managed to cut one off and of course it got all of it off except the part the is still stuck on the shaft. I will try to heat it up and pull it off.

You could also use a die grinder, Dremel, etc., … just be careful not to nick the shaft, or just heat it up a bit …. prior to putting the new bearing on, which by the way you should be able to get locally, emery the shaft slightly and use the NeverSeize. I would take this opportunity to check everything in there, and free up any other areas, and lube or NeverSeize everything. As always, pay careful attention, and DO NOT get any lube material on the rubber Friction Disc or the Drive Plate.

I'm currently using a dremel to get it off. Great minds think alike. Pretty slow sledding but ill get it of.
